I. INTRODUCTION
Under the Clean Air Act, as amended, the Environmental Pro-
tection Agency is charged with the establishment of perfor-
mance standards for new installations or modifications of
existing installations in stationary source categories which
may contribute significantly to air pollution. A performance
standard is a standard for emissions of air pollutants which
reflects the best emission reduction systems that have been
adequately demonstrated (taking into account economic con-
siderations).
The development of realistic performance standards requires
accurate-data on pollutant emissions within the various source
categories. This report presents the results of the testing
which was performed at the Certain-Teed Asphalt Roofing Plant
in Chicago Heights, Illinois on July 22-23, 1975-
The field test work was directed by John W. Brown, Field Testing
Section, Emission Measurement Branch. The visible emissions
were recorded by John W. Brown of the EPA and Tommy L. Stewart
of Monsanto Research Corporation. Process data was recorded
by Dr. K. P. Ananth of Midwest Research Institute.
The opacity of the exhaust stack effluent from the mist elimi-
nator controlling emissions from the seven storage tanks was
observed. Of the seven storage tanks three contained bulk
asphalt, three contained saturator working material and one
contained coating material. Emissions were observed for a
-------
total of twelve hours and included periods of normal opera-
tions, asphalt transfer and heating. The emission opacity
was determined by using EPA Method 9 as given in the Federal
Register Vol. 39, No. 219, November 12, 1974. During the
testing period, observations were made from three locations,
two using the sky as background and the other the dark colored
coater work tank as background.
This report presents a summary of the visible emission data
with the field observation and data sheets included in the
appendix.
-------
II. SUMMARY AND DISCUSSION OF RESULTS
The visible emission data was recorded for a total of twelve
hours over a two day period, with readings being made every
fifteen seconds as specified in Method 9- Observer John W.
Brown (EPA)., Observer No. 1, was certified at NERC, Research
Triangle Park, N. C. on 3-5-75 and observer Tommy L. Stewart
(MRC), Observer No. 2, was certified'by the Ohio EPA, Colum-
bus, Ohio on 3-27-75- In both cases certification is for a
six month period and therefore were valid for the July 22-23
observation period.
During the period there was only one of the fifteen second
readings (12:36:30 on 7-22) when the visible emission was
observed to be above zero opacity. This reading was an opacity
of 10, and was only recorded by one of the two observers due
to the fact that the smoke seen was essentially an instan-
taneous puff, not judged by one observer to have occurred at
the 15 second reading interval. For all practical purposes,
therefore, no visible emissions were observed for the entire
test period.
Neither the routine tank-to-tank asphalt transfers nor the
periodic backflushing of the control device prefilter pro-
duced any outlet emissions that were visibly detectable.
On the first day the weather was good. Overcast skies pre-
vailed and a very light rain fell for about one hour during
the read-ings on the second day. The undesirable weather
-------
conditions were not considered unacceptable as an alternate
high contrast background was utilized for those readings taken
in the rain.
The physical layout of the plant as far as the storage tanks
and mist eliminator is concerned and the location of the
observation points is shown in Figure 1. A summary of the
time of observation, observation points, pertinent distances,
weather conditions, and opacity is presented in Table 1. The
opacity data for the entire twelve hours of reading time is
shown graphically in Figure 2. The summaries of visible
emissions for each sampling period and each observer are
included in this section following Figure 2.

III. PROCESS DESCRIPTION AND OPERATIONS
Emission tests were conducted at Certain-Teed1s asphalt roofing
manufacturing plant at Chicago Heights to determine the opacity
of stack emissions from the Brink® mist eliminator. The Brink®
mist eliminator was used as the emission control system for
the asphalt storage tanks at the plant. Descriptions of the
process involving the tanks, the Brink® emission control system,
and process operation are presented in the following sections.
Process Description
The physical layout of the tanks, including the blowing still,
their dimensions, and the Brink® mist eliminator at the plant
are shown schematically in Figure 3. Tank 4 was under repair
during the tests and was empty.
Asphalt was transferred from the main storage tanks (ST and SJT
at about 260°F to the flux tank (i.e., Tank No. 5) where it
was heated to about *J75°F prior to being oxidized in the blow-
ing still. The flux tank and the four work tanks were equipped
with closed-loop heaters. Tank No. 4 and the flux tank each
had separate heaters whereas Tanks 1, 2, and 3 shared two
heaters. Figure ^ is a schematic of the asphalt flow system
and tank-heater arrangement. Asphalt was pumped from the work
tanks to the manufacturing lines as required. The level and
temperature of asphalt in the tanks and the temperature of
gases and particulates entering the Brink® control system were
16
-------
monitored at half-hour intervals during the tests and these
values are presented in Table 2.
Emission Control System
Emission sources that were controlled by the Brink® unit were
the two main storage tanks, the flux tank and the four work
tanks. Of the four.work tanks, Tank No. 4 was under repair
and valved off from the Brink® unit.
The Brink® mist eliminator basically consists of a vertical
packed fiber bed retained between two concentric cylindrical
screens. Gases containing mist and spray particles pass in
a horizontal direction through the fiber bed. Clean gases
emerge from the bed and rise upward to exit from the system.
The liquid particulates (mist and spray) are collected on the
fibers in the bed and coalesce into liquid films which are
moved horizontally through the fiber bed by the drag of the
gases and then downward by gravity.
The Brink® mist eliminator at the Certain-Teed plant is
equipped with a pref.ilter made of stainless steel mesh. The
prefilter knocks out water and oil sludge and is cleaned once
a month. The packed fiber bed or the Brink® element itself
is backflushed once every 8 hr with no observed difference in
pressure drop which is usually about 13 in. H20. Details on
the Brink® system, as provided by plant personnel, are shown
below:
Manufacturer: Monsanto Enviro-Chem Systems, Inc.
St. Louis, Missouri
Size No.: 2^96
Design Capacity: 1,000 cfm
Blower horsepower: 10
17
-------
Process Operation
Emission tests were conducted when the process was apparently
normal. The work tanks were operated at their normal oper-
ating capacity of 20,000 gal. and the flux tank at its oper-
ating capacity of 18,000 gal. The actual capacities 'of the
work tanks and the flux tank are 25,000 gal. each.
The Brink® element was backflushed during emission test as
per regular plant schedule and no variation was observed
either in the pressure drop or in the opacity of stack emis-
sions .
The quantity of oil collected from the Brink® and from the
ducts leading to the Brink® was also monitored during the
tests and is recorded in Table 1.
Even though the process was apparently normal, there were cer-
tain limitations in the method of operation and in the-tests.
These limitations are detailed below:
1. Methods to establish the quantity of asphalt
in each tank and the temperature of gases
entering Brink® are not precise. The amount
of asphalt in each tank is estimated only
from a visual observation of the float level.
2. The gas temperature range of 80 to 100°P at
the Brink® inlet seems suspect in light of
the fact that ambient temperatures were only
~1 to 5° below that of the gases. The tem-
perature gauge was replaced with another one
available at the plant, but it did not make
a significant difference in the temperatures
recorded.
18
-------
There were no means of verifying the temper-
ature of asphalt in the two main storage
tanks. It was reported to be 260°F through-
out the test by plant personnel but there
were no temperature sensors and plant person-
nel could not even provide the pressure of
steam used for heating the tanks.
The tests do 'not indicate the extent of control
on gases (i.e., gaseous hydrocarbons). It
would be reasonable to expect more gaseous
matter than particulates to escape from hot
asphalt storage tanks.
