18、DUCT MARKETING TERMINAL FACILITIES AND PRODUCTS PPMT FACILITIES PPMTs store refined petroleum products and distribute them to wholesale commercial and retail locations. For example, PPMTs distribute gasoline to service stations, heating oil to homes, and aircraft fuel to airports. Although PPMTs may

19、 differ from each other in some respects, the basic equipment at all PPMTs is the same: storage tanks and truck loading racks. Most product storage is in aboveground vertical storage tanks ranging from 10,000 gallons to over one million gallons in capacity. Horizontal tanks are sometimes utilized fo

20、r small volume storage. A large group of storage tanks is known as a tank farm. A variety of methods is used to deliver petroleum products from the refineries to PPMTs. The most common method of delivering bulk product to a PPMT is by pipeline. In a survey of 57 PPMTs, 63 percent use this method (Br

21、own and Caldwell, 1988). Tankers or barges are used by 30 percent. Lube oil (a more viscous product) is usually delivered by railcar or truck. Upon arrivai at the PPMT, product is transferred and stored in the various tanks until needed for delivery. Product is primarily delivered by truck to consum

22、ers. The product is transferred from PPMT storage into trucks at a loading rack consisting of piping, valves and gauging equipment. Loading racks are equipped with containment systems, which collect any spilled product and rainwater and direct it to a holding tank or retention basin. This prevents s

23、oil contamination by stormwater runoff. 2- 1 Other facilities may be present at PPMTs, but the exact combination of ancillary structures varies considerably among locations. The additional structures may include wastewater treatment systems, truck servicing facilities, warehouses, gasoline additive

24、blending facilities, laboratories, and packaging facilities. Packaging facilities handle lube oil, antifreeze, alcohol, and other specialty products. Wastewater treatment systems vary among the surveyed PPMTs, but ail have oil/water separators to treat their effluents and remove oil and grease. Most

25、 PPMTs have installed vapor recovery units to treat or recycle the volatile petroleum vapors. About half the surveyed PPMTs provide truck washing and maintenance services. DISTRIBUTED PRODUCTS The products handled at PPMTs are mainly motor gasolines and middle distillates. Middle distillates are a g

26、roup of products that include jet fuels, kerosene, diesel, and heating oil. At 57 surveyed PPMTs, 90 percent of the combined storage capacity of 18.5 million barrels (bbl) was for gasolines and middle distillates (Brown and Caldwell, 1988). Several octane grades of motor gasoline are handled at the

27、typical PPMT. Other products less commonly stored at PPMTs include aviation gasoline, lube oil, gasoline additives, and specialty products such as antifreeze. No petroleum or chemical production, beyond blending operations, OCCLUS at PPMT sites. PPMT SIZE The physical size of PPMTs varies considerab

28、ly. Smaller terminals may only be a few acres. In a survey of 57 PPMTs, more than 75 percent were less than 20 acres and had fewer than 10 tanks (Brown and Caldwell, 1988). The remaining 25 percent were larger, and typically covered 60 to 80 acres, having about 20 tanks. 2-2 STD-API/PETRO PUBL 4673-

29、ENGL L979 0732290 0616072 849 6 Section 3 WASTEWATER CHARACTERISTICS AND HANDLING PRACTICES WASTEWATER CLASSIFICATION, SOURCES AND VOLUMES PPMT wastewater originates from different sources and can be classified in a variety of ways. In this report, wastewater is classified on the basis of where it i

30、s collected and the likelihood of its contact with PPMT products. For example, stormwater runoff from vegetated areas, and away from tanks, loading racks, or other facilities, would not iikely come into contact with product stored at the facility. This runoff is classified as “noncontact wastewater.

31、” Areas where contact between stormwater runoff and product is possible would include exposed equipment and loading rack pads. This runoff is classified as “possible contact wastewater.” Water that infiltrates storage tank seals, aqueous condensate in storage tanks, water that enters storage tanks a

32、long with product, and water used to wash facilities or test the integrity of tanks and pipelines definitely does come into contact with product. This water is classified as “contact wastewater. The quality of the wastewater stream determines the means by which it is handled, treated and disposed. A

33、dditional information on wastewater classification and handling procedures is presented in Table 3-1. The relative volumes of the three types of wastewaters are presented in Figure 3-1 (Klock, 1994). Noncontact wastewater is by far the largest volume of wastewater, comprising over 98% of wastewater

34、at a typical PPMT. The next highest volume is possible contact wastewater; comprising about 1% of PPMT wastewater. The lowest volume is contact wastewater at less than 1 % of the total wastewater. The volume of noncontact wastewater at a PPMT site depends upon the size of the terminal grounds and th

35、e local climate. The average amount of stormwater discharged in 1986 from the surveyed PPMTs was 20 million gallons per site. This is equivalent to the annual amount of wastewater discharged by approximately 154 households, each containing five people. In most parts of the country, annual precipitat

36、ion is between 10 and 50 inches per year. Assuming 100% 3-1 STD.API/PETRO PUBL Yb73-ENGL 1999 9 0732290 ObLb093 785 e Table 3- 1.

38、asured as, and assumed to be, the oil and grease content of the sample. Total Petroleum Hydrocarbon - This is a measure of hydrocarbons, the principal components of petroleum products. The analysis dissolves material in a solvent and the dissolved material is measured as, and assumed to be, the tota

39、l petroleum hydrocarbon content of the sample. Biochemical Oxygen Demand (BOD) - This is a measure of how much oxygen will be consumed by bacteria, in decomposing wastewater contaminants. The BOD analysis uses bacteria that consume oxygen while degrading (principally) organic wastewater contaminants

40、. Since most aquatic life requires oxygen, the measurement of oxygen demand in the receiving water is important to ensure that oxygen depletion does not occur in the receiving water. Chemical Oxygen Demand (COD) - This is also a measure of total oxidizable material, but this test uses a chemical oxi

41、dizing agent rather than bacteria. - STD.API/PETRO PUBL 4673-ENGL 5779 = 0732290 0636078 2b7 IpI Total Organic Carbon (TOC) - TOC is an indicator of total soluble organic contaminants. It does not measure inorganic carbon (e.g., carbon dioxide). Ammonia - This is a highly water-soluble byproduct of

42、petroleum refining. It is also present in sanitary wastes fi-om households. Ammonia may be toxic to aquatic life if present at high enough concentrations under certain conditions. pH, Acidity, Alkalinity - pH is a measure of a water?s acid or alkaline strength or intensity. Acidity and alkalinity me

43、asure the water?s base and acid neutralization capacity, respectively. TSS - Total suspended solids is a measure of the quantity of undissolved solids in water and includes soil particles found in stormwater runoff. Aromatics - A class of compounds with ring structures. Benzene, toluene, ethylbenzen

44、e and xylene, known as BTEX, are the principal aromatic constituents of gasoline. TDS - Total dissolved solids is generally considered to be an indication of inorganic salt content. Phenol - A water soluble, slightly acidic aromatic compound often found in gasoline. Phenols - A class of relatively w

45、ater soluble aromatics, derived from the parent compound phenol. Phenols are generally found in waters which contact gasoline. Light Non-Aromatic Hydrocarbons - These are paraffhs and olefins of 5 to 9 carbon atoms and are often the main constituents of gasoline. Ethers and Alcohols - These are cons

46、tituents which may be added to gasoline to improve octane or to comply with EPA requirements for sale of oxygenated gasoline in certain areas of the country. 4-2 - STD.API/PETRO PUBL 4b73-ENGL 1999 0732290 Oblb099 IT3 Surfactants - These are very common materials and the primary constituents of soap

47、s and detergents. They are periodically used for cleaning purposes at terminals and are used as fuel additives. Two categories of surfactants are sometimes measured in wastewaters. These include: (1) methylene blue activate substances (MBAS) or anionic surfactants and (2) cobalt thiocyanate active s

48、ubstances (CTAS) or nonionic surfactants. Metals - Metals are commonly found in terminal wastewater in low concentrations and include: lead, arsenic, iron, copper, zinc, chromium and cadmium. Some of these are found in crude oil, others appear to be from corrosion reactions. 4-3 STD-API/PETRO PUBL 4

Lack of data does not necessarily imply that noncontact wastewater is pristine. Industrial and urban stormwa
