PREFACE
The development of the ASPEN steam stripper model was funded as a cooperative project by
EPA's Control Technology Center (CTC) and EPA's Office of Air Quality Planning and Standards
(OAQPS).
The CTC was established by EPA's Office of Research and Development (ORD) and OAQPS
to provide technical assistance to State and Local air pollution control agencies. Three levels of
assistance can be accessed through the CTC. First, a CTC HOTLINE has been established to provide
telephone assistance on matters relating to air pollution control technology. Second* more in-depth
engineering assistance can be provided when appropriate. Third, the CTC can provide technical guidance
through publication of technical guidance documents, development of personal computer software, and
presentation of workshops on control technology matters.
The technical guidance projects, such as this one, focus on topics of national or regional
interest that are identified through contact with State and Local agencies. In this case, the CTC became
interested in developing an easy-to-use computer model of a steam stripping column equipped with an
appropriate air emission control device. An ASPEN "expert system" was the result of this effort, and it
requires no knowledge of programming to use. This document leads the reader, step-by-step, through
the design and cost estimation procedures in the ASPEN steam stripper model.
OAQPS is developing guidance on controlling emissions from wastewater handling and
treatment. Steam stripping the wastewater is the technology under consideration. However, evaluating
the feasibility of using a steam stripper can be tedious. Therefore, OAQPS and the CTC have
coordinated this effort to provide State and Regional EPA personnel with a tool for quickly and easily
evaluating steam strippers.

1.O INTRODUCTION
1.1 ASPEN STEAM STRIPPER MODEL
The ASPEN process simulation software, VAX/VMS version 7.0, is available to EPA/OAQPS
for evaluating the performance and cost of waste treatment processes. ASPEN is an acronym
representing "Advanced System for Process ENgineering," a software package designed to aid in
engineering calculations. A number of features make ASPEN suitable for modeling waste treatment
systems: (1) modular construction of flowsheets; (2) built-in thermodynamic routines; and (3) ability to
add user models developed for specific applications. Material and energy balance results are used by
ASPEN to size and cost the major pieces of process equipment and calculate the utility and operating
costs. The user has the choice of a "grass-roots" design (design mode) or a simulation that rates an
existing process under new operating conditions (rating mode).
Using these features, an ASPEN model of a steam stripper has been developed. A schematic of
the process is shown in Appendix A. In addition to the tower, the stripper system consists of waste
storage tanks and other vessels, a feed preheater, and a primary water-cooled condenser for the overhead
vapor leaving the stripper.
The overhead product from the steam stripper is condensed and decanted, with the aqueous
condensate routed back to the waste storage tanks. This is done to meet the general objective of
discharging only "clean" residuals from the battery limits of the process. Recovered organics are either
recycled, reused, or incinerated. The treated bottoms from the steam stripper is relatively clean hot
water. It is used to preheat the waste feed to the stripper in a heat exchanger and is then discharged.
Additional unit operations (e.g., catalytic oxidation, vapor-phase carbon adsorption, and
condensation) can be selected by the user for optional control of vapor emissions from the primary
condenser. Simulations with no control option are also possible. Dilute aqueous wastes containing up to
20 chemicals can currently be represented by the ASPEN model.
-------
12 MODEL ASSUMPTIONS. - .,i-^; .
A vertical packed column is a simple device consisting of a cylindrical shell containing a
support plate for the packing material and a liquid- distributing device designed to provide effective
irrigation of the packing. Steam strippers commonly have more than one equilibrium stage for
vapor/liquid mass transfer (Reference 1). The wastewater enters at the top of the column and flows by
gravity countercurrent to the steam. As the wastewater passes down through the column, it contacts
rising vapors that contain progressively less of the volatile organics compounds.
Stripping occurs because the dissolved organics in the wastewater tend to vaporize into the
steam until their vapor and liquid concentrations reach thermodynamic equilibrium. For aqueous
mixtures of volatile organics, the distribution of a pollutant between the vapor phase and water can be
described adequately by Henry's Law (Reference V).
The major parameters affecting a steam stripper performance are the Henry's law constant
for each VOC, the liquid loading rate, and the steam to liquid ratio. The steam and liquid loading
rates and various physical properties affect the mass transfer coefficients for each VOC, whereas, the
Henry's law constant affect the concentration driving force for each of the VOC. The height of a steam
stripper is designed for a certain desired VOC removal efficiency and the column diameter is designed
from flooding correlations to provide a desired pressure drop. In the ASPEN steam stripper model a
pressure drop of 0.5 in - H2O/ft [0.41 kPa/m] of packing (1" stainless steel saddles random dumped
packing) is assumed for column design calculations.
In addition to the above specifications, a number of engineering assumptions were used in
the tower design:
Operating pressure of 1 atmosphere
Isothermal column operation
Constant molal overflow (one mole of aqueous phase vaporized
for each mole of steam condensed)
Linear equilibrium and operating equations
-------
The assumption of linear equilibrium implies that Henry's Law is valid for each volatile
organic at the concentrations encountered, in the stripping column. Air-water Henry's law constants at
25 ฐC are a part of the database for the ASPEN steam stripper model. These are extrapolated to the
column operating temperature using the Clausius-Clapeyron relationship (Reference 2).
The mass transfer model of Onda et al. (Reference 3) is used in the ASPEN model to
calculate an overall liquid-phase mass transfer coefficient. This coefficient is needed to determine the
column height and/or desired removal efficiency. The overall mass transfer coefficient is based on the
two- resistance theory, which states that the total resistance to interphase mass transfer is the sum of a
gas-phase and a liquid-phase resistance. Physically, Kj^a may be thought of as a first-order rate
constant (based on the liquid- phase driving force) which is the product of an overall coefficient, KL
(m/min), times the specific interfacial mass transfer area, a (m ).
The steam stripper model predicts the packing height, Zj, in terms of the operating
parameters and the VOC percent removal:
ZT = (L/KLa)
HTU NTU
Where:
E = VOC removal efficiency expressed as a percentage,
3 2
L = liquid loading, (m of liquid)/m /min,
KLa = overall mass transfer coefficient, min
R = "stripping factor", the operating volumetric G/L ratio
divided by the minimum G/L ratio required for 100
percent removal in an ideal column,
HTU = height of a transfer unit, m,
NTU = number of transfer units.

The ASPEN steam stripper model allows a user a packed or tray column option in both
rating and design modes. In the design mode, auser needs torspecify_a:design^VO.G,component: and s.
its target removal efficiency. - .: -
In a tray column simulation mode Kremser .equations..are: used..to ^relate number of
theoretical trays to the VOC removal efficiency .(Reference 4). A murphree efficiency of 0.& is used to
determine the actual number of trays from theoretical number of trays. When a simulation run is
made in packed colum mode the simulation results also provide an equivalent number of trays
required to achieve the same degree of removal of the design component. Likewise, an equivalent
packing height is calculated for a tray column simulation mode.
1.3 EMISSION CONTROL OPTIONS
Three air emission control technologies are available to the user in the ASPEN steam
stripping model: refrigerated condensation (referred to as a secondary condenser), catalytic oxidation,
and fixed-bed carbon adsorption. The secondary condenser treats the vapor stream leaving the primary,
water- cooled condenser, and it consists of a shell-and-tube heat exchanger equipped with a brine chiller
unit. Catalytic oxidation is a low-temperature (approximately 1100ฐF) incineration unit that uses
methane as an auxiliary fuel to maintain the combustion temperature for dilute organic vapors. Because
no carbon adsorption model currently exists in the ASPEN library, it was necessary to develop and install
a user model for such calculations.
The ASPEN carbon adsorption model is based on a Polanyi-type "universal isotherm"
developed by Calgon Corporation to estimate equilibrium capacities for various carbon adsorbents. For
a given type of carbon, in this case a Calgon BPL (4 x 10 mesh), a single measured isotherm for n-butane
serves as a reference for predicting the equilibrium capacity of any chemical on that same adsorbent.
This reference isotherm is called the characteristic curve for the adsorbent, and its theoretical relationship
to the "adsorption potential" of the adsorbate is well established (Reference 5). By accounting for a
chemical's adsorbed (liquid) density and polarizability, its isotherm can be predicted from the adsorbent's
characteristic curve without experimental data.
Assumptions in the carbon bed-user model .include: (l)-additivity of the equilibrium capacities
of the challenge contaminants, which neglects .competitive-adsorption effects; (2) an overall "working
factor", provided by the user, that accounts for mass transfer"effects and unused bed capacity; (3) sizing
the required carbon mass from the instantaneous organic flows and assumed time of online operation;
and (4) computing the costs for carbon regeneration as well as for periodic carbon replacement.

1.4 PHYSICAL PROPERTIES- -
The steam stripper simulation model requires physical property data to calculate mass and
energy balances. Although ASPEN has a large physical property library for over 400 organic and
inorganic chemicals, additional properties (e.g., Henry's law constant and refractive index) must be
supplied to the model. Henry's law constants are needed for some equilibrium calculations, and
refractive index is related to the polarizability of a chemical in adsorption calculations. A supplementary
library of these properties has been prepared as a part of the steam stripping model so that the user does
not have to supply physical property data for any of the ASPEN- recognized chemicals.

2.0 ASPEN "EXPERT SYSTEM"
2.1 OVERVIEW
In this section, the procedure for creating and running an ASPEN simulation is outlined.
Figure 1. shows the suggested sequence of steps. The user Gist enters information about the problem at
hand into a "front-end" program that converts the user's responses into an ASPEN software file. This
ASPEN file, written to a personal computer disk, is then uploaded to a VAX mainframe and executed. A
report of the simulation results is generated as a VAX file, in standard ASCII format, that can be
downloaded to a personal computer and printed. Each of these steps is described in the following
paragraphs.
2.2 INTERACTIVE FRONT-END PROGRAM
Although ASPEN is a very powerful simulation tool, getting data into an ASPEN input
program and preparing it to run is often a tedious task. Data must be typed manually in a fixed format,
and great care is required in preparing the input information. To make ASPEN easier to use, a "front-
end" program for a personal computer has been developed that will read a general ASPEN input file
(e.g., template), modify it according to information supplied by the user, and then create a new input file
tailored to the problem at hand.
A marker/index system was created for entering information into the general steam stripping
template. In the template, a marker is placed wherever a piece of information may change according to
the user's input. When the front-end program reads the template file and encounters the marker string,
the appropriate piece of information is inserted at the marker.
The new input file can then be uploaded to the VAX and executed according to the ASPEN
run procedure described later. With this "expert system" approach, the ASPEN steam stripping model
can be used without knowledge of ASPEN programming.

23 INSTALLATION AND START-UP PROCEDURES
The Croat-end "expert system" is a Basic computer program that can.be run on an IBM-
compatible (MS-DOS) personal computer equipped with 640K of RAM (random access memory). Color
(RGB/CGA/EGA) and black-and-white (B/W) monitors are supported in a single executable file named
"ASPSTM-EXE". At startup, the program asks the user which type of monitor is installed.
The front-end software has interactive menus and onscreen help and instructions, making
most operations self-explanatory. To run the program from a floppy disk, the following steps should be
performed:
1) Insert the program disk into the designated drive and change the DOS drive
prompt to the appropriate letter (e.g., A>);
2) Type the command "ASPSTM" at the DOS drive prompt and press [Return]
to execute the program;
3) Select a dataset (or set of default values) according to the onscreen start-up
instructions;
4) Follow instructions as they are displayed onscreen and supply information as
requested.
To operate the program from a hard disk instead of a floppy disk, create a hard disk directory
(at the "C > " prompt) with the DOS command "md c:\ASPEN". (This illustration assumes a directory
name of "ASPEN"; any other choice acceptable to DOS will also work.) Then place the original program
diskette into drive A and enter the following DOS command at the "C>" prompt: "copy a:*.*
c:\ASPEN". To run the program, enter the DOS command "cd \ASPEN" at the "C > " prompt and type
"ASPSTM". The program should then run normally according to the above instructions for floppy disk
operation. When duplicating the original program diskette, copy the contents of the entire diskette since
the ASPSTM program uses all of the Gles in the startup directory.
-------
2.4 ENTERING INFORMATION
- The first screen displayed by the front-end program allows the- user to -load-an-eristing-dataset -
or choose the set of default values. The first time the software disk is used; the user must load the default
values from STEAMDAT. During subsequent uses the user may load other datasets he has created and
saved. After loading these values, the Main Menu is displayed. Each menu item flashes when it is
selected with the up/down cursor keys. A reproduction of the Main Menu is shown in Figure 2. Note that
the currently loaded dataset is displayed along with the chosen air emission control option and the choice
of rating/design mode. The user simply selects the items of interest, in any order, from the Main Menu
and enters information about the problem at hand by modifying the entries in the selected dataset. The
program always returns to the Main Menu when data entry for a given item is complete. When all data
has been entered, the user can save his work and create an ASPEN input file at the Main Menu with the
"W" option.
When entering data with the front-end software, each input screen will first be displayed with
default values (in brackets to the right of the screen) for the user to review. A highlighted question at the
bottom of the screen asks if any changes are necessary. If the current entries are acceptable, no further
action is needed and the [Return] key (or "[N]o") displays the next screen. Changes in the displayed
values are made by entering "fY]es" at the bottom of the screen and supplying data at the cursor prompt.
The cursor will begin at the first item, and pressing [Return] at any cursor location will choose the default
value already loaded and move the cursor to the next position. Any entry made by the user will replace
the displayed default value and advance the cursor. Pressing [Esc] at any time (or finishing the data
inputs) will return the user to the bottom of the screen where there will again be an opportunity to review
and/or change the entered information.
Another type of information entry is by a menu with a movable cursor bar. An example is the
chemical selection option available on the Main Menu as item "C". As shown in Figure 3, this item first
displays the default chemical list and provides the user with three options: (1) to delete one or more
chemical's from the default list; (2) to add more chemicals; and (3) to make no changes. A toggle key,
[Fl], alternately displays the component numbers above 10 and below 10, respectively, if more than 10
are loaded. Deletions are updated immediately on the screen.

Adding chemicals causes a scrolling list of chemical names to appear onscreen (see Figure 4),
and the [T] and [U] keys can be used to [T]ag and [U]ntag selected chemicals. In the unlikely event that
a chemical of interest is not present in the ASPEN library, it is recommended that a- surrogate chemical
with similar structure and properties be selected from the available list. When the chemical selection is
complete, the user then has the option of reviewing and modifying the Henry's law constants available for
the chosen compounds.
2 J CREATING A CUSTOM ASPEN INPUT FILE
Referring again to the Main Menu (see Figure 2), the "S" selection saves the user's
information entries in a named dataset file (with a ".dat" extension) for future recall. It is recommended
that this feature be used frequently when creating a simulation to protect the work against accident. As a
precaution, the user is reminded by the front-end program to save his work before leaving the program
with the Main Menu "Q" selection.
The "W" selection in the Main Menu will both save the current dataset and create a custom,
ready-to-run ASPEN input file (with a ".inp" extension). A third file, with a ".prl" extension, is also
created by the "S" and "W" main menu commands as a summary report of the data entered by the user.
The user supplies a name that is used for the dataset, input file, and input data report (e.g.,
"example.dat", "example.inp", and "example.prl"). This naming convention is useful for determining
which dataset was used to create a particular input file and input data report.
While preparing a dataset to be used to create an ASPEN input file, the user will be prompted
to supply a 4-character run identification string (referred to in the guide as RNID). It is important that
the name selected for the dataset not begin with the RNID. The use of the RNID is discussed further in
Section 4.2.

3.0 USING ASPEN ON THE VAX
Use of the ASPEN steam stripper model involves using a personal computer (PC) as a
computer terminal to connect to the EPA National Computer Center (NCG) VAX Cluster; transferring
computer files from the personal computer to the VAX, and executing the ASPEN model through the
computer terminal. The procedures given below are to be followed to ensure proper execution of the
ASPEN program.
Questions relating to the use of the ASPEN program can be directed to Mr. Robert Blaszczak.
Control Technology Center, U.S. EPA at (919) 541-5432. This user's guide has been written to provide
enough information for user to complete an ASPEN run. However, information regarding the services
provided by and operations of NCC are contained in the publication titled Guide to NCC Services.
published by U.S. EPA, Office of Administration and Resources Management, National Data
Processing Division. A copy may be requested from user support services at the telephone number
listed below. The "VAX Cluster Ready Reference" section in the guide provides essential information
for users of NCC's VAX computers. Basic descriptions of procedures, utilities, languages, and software
are included in the VAX online documentation. The NCC comprehensive user support service may be
reached at (FTS) 629-7862 or (919)541-7862, or (800) 334-2405 for users outside North Carolina.
3.1 SETTING UP A USER ACCOUNT
Currently, the APSEN steam stripper model is available on the VAX Cluster located at NCC.
Research Triangle Park, North Carolina. Each new user must obtain a user ID and account code to
gain access to the computer. Users who already have these items and know how to use them at their
own computer terminals may proceed immediately to Subsection 3.2.
Obtaining an account on the VAX computer at NCC requires submission of a user
registration form for approval by the EPA account manager or ADP coordinator. This form, EPA
Form N258, is used whether or not the new user is an EPA employee. A sample Form N258 is included
in Appendix B.
For EPA users, the form is signed and submitted by the Automatic Data Processing (ADP)
Coordinator of the user's EPA organization and sent to the Time Sharing Services Management System
(TSSMS) Office at the address shown on the form. Non-EPA users must be in an organization that has
established an Inter-agency Agreement (IAG) with EPA. If the IAG is with a Regional Organization
(RO), the form is submitted to one of the 10 regional ADP Coordinators as shown in Table 1.

3.2 ACCESSING THE VAX USING PERSONAL COMPUTERS
After receiving an account code, user-ID, and password from TSSMS, and creating a custom
ASPEN input file on a personal computer with the front-end software as described in Subsection 2.5, the
next step is to connect the personal computer with the NCC VAX Cluster. The personal computer is
used as a terminal to upload the ASPEN input file and to run the ASPEN program on the NCC VAX.
The following procedures are used for personal computers because they are capable of both generating
the ASPEN input file and serving as a computer terminal. In the following text, prompts from the VAX
system are enclosed by " ", and response to a prompt is enclosed by < >, and specific keys to be
pressed are enclosed by [ ]. It is not necessary to type these symbols in the operations.
Using a personal computer as a terminal, a user can dial-up the NCC VAX Cluster by a
modem through a telephone line. Since there is a wide variety of communication packages and modems
that can be used, users should refer to their hardware and software documentation for specific
instructions. There are, however, some general guidelines that apply to all types of communications
with the VAX:
Connection can be made at either 1200 or 2400 baud.
Communication software should be set to emulate a VT-100 type terminal. - . -
Communication parameters should be 7 data bits, 1 stop bit, and even parity (An
example of communication parameters setting for Crosstalk communication .software
is included in Appendix C).
Local users in Research Triangle Park, North Carolina can dial up the Port Selector switch
directly at (919) 541-4642 or (FTS) 629-4642 for 1200 baud, or at (949) 541-0700 or (FTS> 629-0700 for-
2400 baud. When the connection is made, press [Enter] once to display the Port Selection menu as
shown in Figure 5.

332 Transferring Files from a Personal Computerto the=VAX
Before using the ASPEN software, it is necessary to upload the ASPEN input file,
XXXXJNP, created with the front-end program described in Subsection 2.5, to the VAX. First
time users also need to upload a LOGIN.COM file which is supplied along with the front-end
software. File transfers are accomplished using the Kermit file transfer protocol on the VAX and
the PC. The following steps would be used for a personal computer using Crosstalk
communication software.
1. At the "$" prompt, type < KERMIT > [Enter] and wait for a "Kermit-32>"
prompt to appear.
2. At the "Kermit-32>" prompt, type. [Enter].
(XXXX is the file name and YYY is its extension you give to the file you are
going to transfer from the personal computer and store on the VAX.) At this
point, the VAX will pause and wait for the file transfer to be initiated from the
user's personal computer.
3. Press [Home] to display Crosstalk's command line at the bottom of the screen
(e.g., "Command?") and type [Enter] to
start the file transmission. (DISKDRIVE may be any disk drive or a directory
on a hard disk drive, XXXX.YYY is the name of the ASPEN input file with the
extension JNP or LOGIN.COM file.)
4. Paced, error-checked transmission of the ASPEN input file or LOGIN.COM
file then begins. When the transfer is complete the message "file transmission
complete" will appear on the screen for Crosstalk. Other communication
software will display messages such as "more to come . . . press ENTER" or
supply a sound signal prompt to indicate the file transfer is complete.
During file transfer an error indication may appear on the screen. Most
communication software will retransmit the portion of the file in which the
error occurred, therefore correcting the error automatically. If too many
errors occur (number varies according to software specification) the transfer
will terminate in an error condition. In this case go to step 5 and repeat step 2
through 4 for the same file.

5. Press [Enter]* thenpIomeJ^en^EnterJtO'Obtaaiihe 'AKeE^t^x?* prompt.-
6. If more than one file is being transferred, repeat steps 2 through-5 for each file.
7. When all files are transferred, type to return to the "$" prompt on
the VAX.
333 Copying Library Files to User Account for First Time Users
New users using ASPEN for the first time should copy two library files from another
directory on the VAX before making any run on the ASPEN program. These files can be copied
as follows:
1. At the "$" prompt, type
[Enter], then wait for the "$" prompt.
2. At the "$" prompt, type
[Enter], then wait for the "$" prompt.
33.4 Running the ASPEN Steam Stripper Program on the VAX
First time users, should have 4 files on the VAX under their directory. These are:
USERLIB.OLB, USERUB.OPT, LOGIN.COM, and the ASPEN input file XXXX.INP.
(XXXX is the file name assigned to the file with the specific extension ".IMP" for the input file.)
When the LOGIN.COM file is initially uploaded from the PC, the file should be executed once
using the command in step 1 below. Otherwise, proceed to step 2.
1. At the "$" prompt, type < ฉLOGIN.COM > [Enter] to execute the login
command file one time, then wait for the "$" prompt.
-22-
-------
2. At the "$" prompt, type [Enter] to check if all the
necessary files are present If not, return to Subsections 33.2 or 333 and
follow the procedures to upload or copy the needed files.
3. At the "$" prompt, type < ASPEN > [Enter] and respond to the prompt
"Please enter input file name (? for help)" with [Enter], or
type < ASPEN XXXX> [Enter] directly to initiate the ASPEN program.
4. At this point, a screen prompt asks whether the input file contains inserts or
user libraries. Respond with [Enter],
5. At the "$" prompt, the VAX will respond with the message "Job XXXX
(queue aaaa, entry nnn) started on bbbb_bbb", then followed by another "$"
prompt.
6. When the run is completed, the VAX displays a message "Job XXXX (queue
bbbb_bbb, entry nnn) completed" at the "$" prompt. This will be followed by
another "$" prompt.
7. Type [Enter] to check if the result files for a
successful run are generated. These should include: ZZZZ.HIS, ZZZZ.LOG,
ZZZZ.PRM, and ZZZZ.REP files. In this case ZZZZ is the RNID specified
in the input file (see Section 4.2).
8. If the result files are not generated, type [Enter] to
list the log file which will contain any error messages that might have been
issued by the ASPEN software or VAX system software. You may press
[CtrI] + [S] simultaneously to pause the display, [Ctrl] + [Q] to resume
scrolling, or press [Ctrl] + [C] or [Ctrl] + [Y] to exit from scrolling.
3.3.5 Transferring Output Files from the EPA-VAX to a Personal Computer
The result files generated by the ASPEN program can be downloaded from the VAX
to a personal computer if desired. The procedures for downloading are identical to those in
Subsection 3.3.2 for uploading, except steps 2 and 3 are replaced by the following two steps.
-23
-------
2. At the "Kermit-32>" prompt, type ~[Ehter].~ (XXXX"
is the file name ancbYYY-is its extension-thatyou:are jomg4ordownload-from-r
theVAX.)
3. Press [Home] to display Crosstalk's command line at the bottom of the screen
(e.g., "Command?") and type [Enter] to
start the file transmission.
Downloading XXXXJPR2 file will take about 1 minute at 1200 baud.
3.3.6 Logging Out Procedures
1. At the "$" prompt, type < LOGOFF > [Enter] to disconnect your personal
computer from the VAX. The screen will show "NO CARRIER" after a short
message.
2. Press [Home] to display Crosstalk's command line at the bottom of the screen
(e.g., "Command?") and type to exit from Crosstalk.
At this stage, you have completed the operation of running ASPEN on the VAX
through a personal computer. Word processing software or a text editor can be used on a
personal computer to view or print the downloaded ASPEN output flies.

4.0 SIMULATION RESULTS -
The procedures used to estimate capital and annual costs for this simulation are
intended to be of preliminary "study" estimate quality. Study estimates are accurate -to -_+. -30
percent and are used to estimate economic feasibility of a project with a relatively low cost for
estimate preparation and based on minimum data (Reference 2). The algorithms-and
compound data used to compute estimated stripping column heights or estimated column
performance for specific chemicals yield approximate results. To prepare a stripper design or
rate column performance for purposes of obtaining vendor guarantees, many more details on
specific site conditions such as feed variability, steam quality, and annual variations in cooling
water temperatures are required.
4.1 COST CALCULATIONS
The steam stripper model contains costing procedures developed by EPA/OAQPS,
Economic Analysis Branch (EAB) and published in the EAB Control Cost Manual (Reference
6). The cost results are indexed for convenience to January 1986 and can be adjusted to any
desired year using an appropriate Chemical Engineering Plant Cost Index. Figure 7 summarizes
the main components of the total annual cost. Currently, no organic recovery credit is included
in the cost calculations. A cost summary like the one presented in Appendix A is generated as
part of the ASPEN report output.
The Total Annual Cost (TAG) is the sum of the direct annual costs (e.g., utilities, labor,
and maintenance) and the indirect annual costs (e.g., overhead, property taxes, insurance,
administrative charges, and capital recovery). Annualized capital costs are combined with fixed
operating costs to give a levelized yearly expenditure that can be compared directly to that of
other processes.
4.2 REPORT OUTPUT
Prior to creation of a custom ASPEN input file, the front-end program asks the user for
a 4-character run identification string (referred to in this discussion'as RNID). -The ASPEN
system uses this run ID to create files in the VAX disk directory where the simulation is
executed. Several of these files are worth noting because they contain error messages,
intermediate calculations, or simulation results. A severe error in input file syntax or format

severe errors and warnings, as well as intermediate calculations, can be found in a file named
"RNID.HIS" (called the ASPEN History File). Tfie final report for-the simulation is mamed
"RNID.REP" (called the ASPEN Report File).- : ~-
NOTE: Because ASPEN creates a large number of output files (particularly
for runs that abort prematurely), an ASPEN utility program called
"GETRIDOP' is available on the VAX to erase unwanted
simulation results. For example, the command "GERTRIDOF
TST1" would delete all VAX files beginning with the run ID 'TST1".
To avoid accidental file erasures, NEVER give the custom ASPEN
input file (or any other file you want to keep!) a name that begins
with the RNID.
A report from a simulation run consists of three parts: background material, a summary of
input data prepared by the front-end program from the user's inputs, and a performance and
economic analysis generated by ASPEN. The background material consists of a process schematic and
a general narrative description of the ASPEN model. Copies of these are kept on file for each of the
possible process configurations.
The second and third sections of the report are stored in files with the same base name as
the parent dataset/input file and extensions of ".prl" and ".pr2" respectively. The input data summary,
"example.prl", is created by the front-end program on a personal computer (with either the "S" or
"W" main menu options) and can be routed to a printer with any of several DOS commands (for
example, "copy example.prl Iptl:", where Iptl: is a line printer connected to parallel port 1). This is
done after exiting the front-end program to generate a "hard copy" of the data that has been entered.
An ASPEN results summary, "example.pr2'Y is created as a VAX file during the course of the
simulation run and can be downloaded to a personal computer (for printing) according to the
procedures outlined earlier.
Put together, these parts provide a complete report of the. simulation-results, including
background information and a schematic of the process being modeled: -As an example, Appendix A
contains a case report created for a steam stripper equipped with a vapor-phase carbon adsorber for
control of steam emissions. Finally, the History and Report Files on the VAX can be downloaded
and/or printed, if necessary, to provide supporting calculations suitable for technical reference.

APPENDIX A
A Sample Case Study

-------
STEAM STRIPPER MODEL BACKGROUND; .
U.S. EPA-Office of A1r Quality Planning and Standards (EPA-OAQPS), has
sponsored development of an ASPEN user model to describe the process of steam
stripping of the volatile organic chemicals from wastewater feed stream. In
addition a completely Interactive software has also been developed to allow a
user running an ASPEN steam stripping simulation without any knowledge of
ASPEN programming. ASPEN is an acronym representing "Advanced System for
Processing Engineering," a software package available commercially for
chemical process design and simulation. ASPEN allows modular building of
flowsheet blocks to represent a steam stripper with or without air emission
controls. It also contains an extensive physical property library and costing
routines.
The process simulated by the steam stripping model is shown schematically
in Figure A-l. This model can be run in one of two modes: rating mode and
design mode. In the rating mode a specific, known steam stripper design can
be evaluated by inputting basic design parameters such as flow rates,
concentrations, and tower dimensions and then comparing the predicted
performance results with observed ones. Similar information would also be
required for any existing air emission control device. The rating mode also
allows "what if..." calculations by changing the operating parameters such as
steam/water ratio and influent concentrations.
In the design mode one needs to provide only the wastewater flow rate,
influent concentrations, desired removal rates or effluent concentrations, and
the air emission control selected. The model will calculate the necessary
optimum tower design to achieve the specified effluent limits, and provide
sizing information for the selected control equipment. In both modes the
steam stripper ASPEN model determines the capital and operating costs
-------
associated with the stripper as well as.-the control equipment. >The output for .
each mode 1s provided 1n units typically^ used in. .describing equipment
dimensions, flows, and concentrations. _-,.: ,
The ASPEN steam stripper model allows three, options-for controlling the
VOC air emissions: 1) condensation of additional vapors using a refrigerant
in a secondary condenser, 2) adsorption on a fixed bed of activated carbon,
and 3) catalytic oxidation of the VOC's at an appropriate temperature to
assure complete destruction of the VOC's. A model has also been developed for
describing adsorption of the VOC's on carbon based on Polanyi's 'generalized
isotherm' concept. The catalytic oxidation operation uses an auxiliary fuel
such as natural gas to maintain the desired temperature of the catalytic
combustor.

16. ABSTRACT
ASPEN is an acronym representing "Advanced System for Process Engineering," a
software package designed to aid in engineering calculations. Using these features,
an ASPEN model of a steam stripper has been developed. Steam stripping is the
technology under- consideration-by-the EPA for- con-trol-ling emissions from-wastewater. -
Although ASPEN is a powerful tool, it is difficult and tedious to use. The
purpose of this diskette and user's guide is to provide State and Federal EPA personnel
th an easy to use front-end program for evaluating steam strippers. The program
prompts'the user for inputs and creates an ASPEN input file that can be uploaded to
a VAX matin frame and executed.
