Generally, industries defined in this way will employ simi- lar technologies, have common types of environmental impacts, and will be sup- plying their products for further processing or consumption to the same general population of customers. Each industry is designated a chapter in the catalog. Chapters are numbered consecutively and bound individually. In all* twenty- five chapters are presented in this, the first edition of IPPEU. USES OF IPPEU An environmentally oriented central file of industrial process informa- tion is expected to have many uses. Some of those applications that are readily identified include: 1. A system of cataloging relevant information which has been generated by air, water, and solid waste groups who have been conducting industry studies. t 2. The formation of an industry-process-pollutant matrix that highlights those emissions to air, land, and water that are-most significant and those that are known to be hazardous. 3. The identification of possible new waste stream problems. 4. Provision of process synopses for quick reference and bibliography of sources for more complete information. 5. Means for gaining individual industry and process perspective as well as perspective on industry inter- relationships. 6. A basic knowledge of the processes that will allow the full range of environmental control strategies to be studies and evaluated. 7. Aid in coordinating EPA's research program and efforts in air, land, and water pollution abatement. 8. Identification of process and waste stream information that is not known, resulting in the initiation of more efficient and comprehensive characterization programs. ------- 9. Establishment of research priorities based on source as- sessment of the waste streams from readily identifiable processes. 10. Providing process and waste stream information to help in designing test programs, source sampling equipment, and process control equipment. 11. Use by educators as a research reference source and teaching aid. 12. Use by industrial consultants and designers to broaden the applicability of their knowledge as well as pinpoint their areas of expertise. APPROACH TO CATALOG DEVELOPMENT Early in the program, consideration was given to use of the Department of Commerce's Standard Industrial Classification (SIC) Manual as a basis of defining industries. It was concluded that while some SIC categories seemed to be appropriate, others were not. It was decided that industries would be identified through analysis of present commercial and industrial practices. As a first step, all industrial categories in the SIC were analyzed and the following six industry categories were identified: 1. Fossil fuel extraction - (e.g., oil and gas, coal), 2. Mineral extraction and chemical processing - (e.g., iron and steel petroleum refining* industrial organic chemicals), 3. Agricultural and forest products - (e.g., pulp and paper, grain farming), 4. Compounding and fabrication - (e.g., motor vehicles, machine tools, paint and varnish), 5. Public service industries - (e.g., utilities, sewage treatment), and 6. Public service (trade and commerce) - (e.g., gasoline stations, dry cleaning, auto repair). In development of the catalog to date, primary attention has been given to those industries which process primary raw materials such as ores, non- metallic minerals, coal and oil (category 2 above). The primary raw materials for industries in category 2 are shown in Table 1. After extraction, most of the raw materials are used in one of more of the following three ways: (1) directly and innocuously consumed after a relatively simple pretreatment (sand and gravel, limestone, etc); (2) used after physical processing to ------- Table 1.

Those industries producing metals and chemicals and downstream industries which are in the chain leading to consumer products involve some 12,000 processes which include the industrial activities having greatest potential for environmental impact; hence, these have been given first consideration. Additional subjective bases for selection of industries to be considered for later issues and for assigning priorities in their evaluation were used. For the industries involving food and forest product (category 3) only those whose environmental impacts are considered as bad as or worse than the mineral- based industries were considered. Several activities classified as compounding and fabrication (category 4) were considered desirable for study because of important associated environmental effects. Industries involved with public service activities (categories 5 and 6) were considered beyond the scope of the first edition. High priorities were established for industries involving process materials having published adverse health effects. After identification of the primary raw materials, the usage of products and by-products from the industries consuming the primary raw materials was traced; e.g., the oil and gas production industry supplies feedstocks for the petroleum refining industry which in turn supplies feedstocks for the basic petrochemicals industry and the industrial organic chemicals industry (I.O.C.I.) A significant fraction of the petrochemical industry's output serves as ad- ditional feedstock to the I.O.C.I. This industry produces some 400 chemicals which are the building blocks for many industries such as organic dyes and pigments, pesticides, medicinal chemicals, etc. The complexities of some of these downstream industries can be illustrated by considering that the organic dyes and pigments industry converts some 100 raw materials through approxi- mately 900 intermediate chemicals into more than 2000 color products. Industries to be considered were defined by assessing the commonality of raw materials, products, and markets for populations of companies which were believed to represent a "real world" industry. In some situations this was a relatively simple task as in the cases of the petroleum refinery industry, the iron and steel industry, and the primary aluminum industry. For others such as those involving synthetic organic products the task was more complex. De- finition of industry boundaries in this situation involved first identifying companies primarily in the business of producing organic chemicals for further conversion. The boundaries of the I.O.C.I, were established by starting with 10 basic petrochemical feedstocks and constructing a chemical tree which showed downstream derivative chemicals. The tree was terminated when the chemical species under consideration were shown to be predominately feedstocks for one or more other industries. These other industries involved a significantly different population of companies which converted the industrial organic ------- chemical (i.e., mainly solvents and chemical intermediates) into products for consumption; e.g., organic dyes and pigments, plastics and resins, and synthetic fibers. The high level of integration of the larger companies in the I.O.C.I. with downstream industries made this industry definition task difficult in some instances, but it is felt that the boundaries as presently established are sufficiently precise to (1) permit understanding of the realtionship between products, and (2) identify all processes with significant environmental impact. The industries described in this effort are shown in Table 2. CATALOG FORMAT After identification of an industry the next step was to identify the environmentally significant processes which make up the industry. This was accomplished by considering the kinds of equipment and the nature of the input and output materials for each processing step involved in the conversion of input raw materials into products. Based on this information a schematic process flow sheet of the type shown in Figure 1 for the crude separation segment of the petroleum refining industry was developed. After identifica- tion of industry boundaries and the population of processes of concern, process descriptions were developed. Figure 2 illustrates the format for the process descriptions. The example is process description number 2, Desalting, from the Crude Separation Segment of the Petroleum Refining Industry. The format for each chapter consists of the following elements: • Industry Description raw materials products companies environmental impact bibliography • Industry Analysis Segment A chemical (product) tree process flowsheets process descriptions Segment B, etc. • Appendices raw material list product list company list other pertinent data The industry description discusses the companies, raw materials, products. and environmental impacts in broad terms. These are typically 10-20 pages in ------- Table 2.

EXAMPLE SCHEMATIC PROCESS FLOW SHEET. CRUDE SEPARATION SEGMENT OF THE PETROLEUM REFINING INDUSTRY (CHAPTER 3) ------- CRUDE SEPARATION PROCESS NO. 2 Desalting 1. Function - The desalting unit is generally the first processing unit in a crude oil refining scheme. This process is used to'remove salt, water, and water soluble compounds from the crude, as these compounds can eventually result in equipment fouling, corrosion, or possible catalyst poisoning in downstream processing units. Water 1s added to the incoming raw crude and thoroughly mixed. The wet crude is then heated to break emulsions and the water and dissolved im- purities are separated. Separation is accomo1, ished by physical decanting and electrostatic coalescing. The separated water is collected and sent to the waste water treating system, and the deslated crude is preheated and sent to the atmospheric distillation column. 2. Input Materials - The fuel to the desalting unit is crude oil from storage. 3. Operating Parameters - Temperature: 38-155°C (100-300°F) Pressure: 2.8+ kg/sq cm (40+ psi) 4. Utilities - Thermal Energy: 34,800 kcal per m3 of crude charge (22,000 Btu/bbl) may be obtained by heat exchange with a hot stream from the distillation column or by process heaters Electricity: .063 kWh/m3 - used to run pumps and the coalescer Process Water: 35-60 liters per m3 of crude charged (1.5-2.5.gal/bbl) 5. Waste Streams - Only a liquid effluent is released from this unit. The effluent rate is about 47 liters per m3 of oil processes. The largest waste water contaminants are dissolved solids (average concentration 3700 ppm) which are composed largely of chlorides, sulfates, and bi- carbonates. Oil, phenols, and sulfides are also found, but in lesser concentrations. Average concentrations for these pollutants are 169, 15, and 4 ppm, respectively. 6. EPA Source Classification - None exists. 7.

The industry analysis section presents the process flowsheet and information on individual processes and their interrelationships. Process descriptions typically are 1 to 2 pages long. Information on effluent streams and other environmentally relevant information is presented chiefly for project managers and others interested in process details. The chemical (product) tree gives an overview for material flow through the industry. The appendix presents detailed information on companies, raw materials, products and environmental impacts. Other pertinent data too lengthy to include with the process or industry descriptions are also in the appendix. It is expected that some industry entries will depart from the standard format. For example, the organic dyes and pigments industry is too complex to permit development of industrial process descriptions for each of the several thousand involved. In this situation class descriptions are presented for the more important color products, and the interrelationships within the industry segment involving production of intermediates are depicted by a chemical tree rather than a detailed process flow sheet. "~-v, Boilers represent another special situation in that the types of boilers used will generally be common to many industries. It is anticipated therefore that a special boiler catalog entry will be developed. PRESENT STATUS - FUTURE PROGRAMS This effort contains 24 completed industry catalog entries. An additional 15 will be needed to complete the assessment of those industries based on ex- tracted minerals (category 2). It is anticipated that the ten most offensive industries based on food and forest products (category 3) will be considered. In addition, work will be undertaken to define problems associated with the compounding and fabrication industries. A listing of planned or current in- dustry studies is shown in Table 3. Revision to published entr-'es are antici- pated as the need arises. Computer storage of the data contained in each chapter is possible. This will allow the rapid assembly of data based on a particular emission with its associated processes and industries. The utility of the catalog would be increased by this ability to rapidly identify the known sources of a particular emission. The computer program could be flexible enough to allow the retrieval of data based on a compound, product, process, control device, or industry. :1f not art- Suggestions for improving the catalog are welcome. The usefulness of the catalog to people involved with environmental problems can best be met by feedback from the users of the IPPEU.

The catalog resulted from the work of many contributors from different companies,, Some of the chapters in this first edition employ no- menclature which differs from the definitions listed here = For instance, the word segment is used for the concept defined here as plant or operation. While these variations occur in many chapters, nomenclature is generally con- sistent within each chapter. 1. RAW MATERIALS are feed materials for "processes." They are of two types: primary raw materials that are used in the chemical form in which they were taken from the land, water, or air and secondary raw materials that are produced by other "industries." 2. INDUSTRIES are made up of groups of "companies" that are considered competitors in production.of the same products. Industries have an identifiable population of companies and have a high degree of commonality with respect to raw materials consumed, processes employed, products produced, environmental control problems experienced, pollutants pro- duced and control equipment used. 3. SEGMENTS are separate groups of companies within an industry. The companies within a segment form a subset. They may differ from other companies in the industry in one or more of the elements in the definition for industries. The companies in a segment may also employ processes and produce products that are classified in the industry as a whole or in other indus- tries. 4. PROCESSES can be considered the basic units that collectively describe industries. All industries are in practice made up of sets of processes that have some degree of environmental impact associated with their operation. Processes are em- ployed to produce chemical or physical transformation of input materials into "end products", "intermediate products", secondary raw materials or waste materials. Input materials can include primary or secondary raw materials, waste materials, or intermediate products. 5. PROCESS STEPS are the basic components of a process that utilize process equipment or materials handling equipment. (Process equipment includes only those components essential to economic operation of a process and does not include "control equipment.") 6. SOURCES are process steps from which significant amounts of emissions to the environment occur. 7. CONTROL EQUIPMENT is equipment whose primary function is to reduce emissions to the environment. Its presence is not es- sential to the economic viability of the process. 12 ------- 8- COMPANIES include corporate subdivisions that have a product slate similar to other companies in an industry. 9. PLANTS OR OPERATIONS are comprised of collections of processes to produce the products associated with their industry. Indi- vidual plants within an industry may employ different combina- tions of processes but all plants will be comprised of some of the processes that are common to the industry. 10. END PRODUCTS include only those process outputs that are marketed for use or consumption in the form that they exit from the process. After use, an end product becomes a "waste material." 11. INTERMEDIATE PRODUCTS are process output streams that go either to other processes in the same industry in which they are pro- duced, or to other industries where they become secondary raw materials. 12. WASTE MATERIALS are either process outputs that go to a scavenging industry, or are used end products that are disposed of or processed to recover reusable constituents. 13. WASTE STREAMS are a non-product discharge to the ambient air, water, or land from an energy system or industrial process. 13 ------- TECHNICAL REPORT DATA (Please read'Instructions on the reverse before completing) 1.

ABSTRACT The catalog was developed to aid in defining the environmental impacts of U.S. indus- trial activity.'" Entries for each industry are in consistent format and form separate chapters of the catalog. Chapter 1 is an introduction to the catalog and identifies a number of expected uses for the information contained in the various chapters. It explains the approach to catalog development, as well as the basic catalog format. It provides examples of typical information to be found in subsequent chapters, along with definitions for specific catalog nomenclature. It presents plans for future programs for the assessment of industrial processes and their impact on the environ- ment. 7.
