Pollution petroleum products

The practice of smudging is still carried out in many areas to protect orchards from frost. Petroleum products are burned in pots, producing both heat and smoke. Since the heat is the desirable product, smokeless heaters with return ducts to reburn the smoke are required by most air pollution control agencies. Some control agencies have passed regulations limiting the smoke to 0.5 or 1.0 gm per minute per burner. 

The pollutant ouqiuts from the refining facilities, however, are modest in comparison to the pollutant outputs realized from the consumption of petroleum products by the transportation sector, electric utilities, chemical manufacturers, and other industrial and commercial users. 

Transportation accounts for about one-fourth of the primary energy consumption in the United States. And unlike other sectors of the economy that can easily switch to cleaner natural gas or electricity, automobiles, trucks, nonroad vehicles, and buses are powered by internal-combustion engines burning petroleum products that produce carbon dioxide, carbon monoxide, nitrogen oxides, and hydrocarbons. Efforts are under way to accelerate the introduction of electric, fuel-cell, and hybrid (electric and fuel) vehicles to replace sonic of these vehicles in both the retail marketplace and in commercial, government, public transit, and private fleets. These vehicles dramatically reduce harmful pollutants and reduce carbon dioxide emissions by as much as 50 percent or more compared to gasoline-powered vehicles. 

RH above can represent a very wide variety of xenobi-otics, including drugs, carcinogens, pesticides, petroleum products, and pollutants (such as a mixture of PCBs). In addition, endogenous compounds, such as certain steroids, eicosanoids, fatty acids, and retinoids, are also substrates. The substrates are generally lipophilic and are rendered more hydrophilic by hydroxy-lation. 

Table 1 indicates primary pollutant sources and waste modes, and Table 2 indicates the primary and secondary sources and associated pollutants. The primary sources of soil contamination include land disposal of solid waste sludge and waste-water industrial activities and leakages and spills, primarily of petroleum products. The solid waste disposal sites include dumps, landfills, sanitary landfills, and secured landfills. 

The sulfur compounds that are present in minor quantities in petroleum products also exhibit a typical gas chromatographic fingerprint easily obtained by flame photometric detection. This fingerprint has been introduced to complement the flame ionisation detection chromatogram with the aim of resolving the ambiguities or increasing the reliability in the identification of the pollutants [74].

Atomic absorption spectrometry is one of the most widely used techniques for the determination of metals at trace levels in solution. Its popularity as compared with that of flame emission is due to its relative freedom from interferences by inter-element effects and its relative insensitivity to variations in flame temperature. Only for the routine determination of alkali and alkaline earth metals, is flame photometry usually preferred. Over sixty elements can be determined in almost any matrix by atomic absorption. Examples include heavy metals in body fluids, polluted waters, foodstuffs, soft drinks and beer, the analysis of metallurgical and geochemical samples and the determination of many metals in soils, crude oils, petroleum products and plastics. Detection limits generally lie in the range 100-0.1 ppb (Table 8.4) but these can be improved by chemical pre-concentration procedures involving solvent extraction or ion exchange. 

Considering the composition of petroleum and petroleum products (Speight, 1994, 1999), it is not surprising that petroleum and petroleum-derived chemicals are environmental pollutants (Loeher, 1992 Olschewsky and Megna, 1992). The world s economy is highly dependent on petroleum for energy production, and widespread use has led to enormous releases to the environment of petroleum, petroleum products, exhaust from internal combustion engines, emissions from oil-fired power plants, and industrial emissions where fuel oil is employed. 

Having defined the process products and emission (Chapters 3 and 4), pollution prevention is the operational guideline for refinery operators, process engineers, process chemists, and for that matter, anyone who handles petroleum and/or petroleum products. It is in this area that environmental analysis plays a major role (EPA, 2004). 

Pollution associated with petroleum refining typically includes volatile organic compounds (volatile organic compounds), carbon monoxide (CO), sulfur oxides (SO c), nitrogen oxides (NO ), particulates, ammonia (NH3), hydrogen sulfide (H2S), metals, spent acids, and numerous toxic organic compounds (Hydrocarbon Processing, 2003). Sulfur and metals result from the impurities in crude oil. The other wastes represent losses of feedstock and petroleum products. 

The purpose of this chapter is to present a description of the methods by which petroleum products-effluents-emissions are treated in an attempt to ensure that pollution does not occur and products-effluents-emissions fall within legislative specifications. Indeed, as already noted, enviromnental analysis is the major... 

There are many areas of the chemical industry that are responsible for the release of pollutants into the enviromnent. Petroleum refining is one such industry that has seen inadvertent spillage of unrefined petroleum and petroleum products. Since the beginning of the environmental movement in the 1960s, the continuing question relates to the relative condition of the environment. 

The book will serve as a reference for analysts in detailing the steps required to identify petroleum and petroleum products (although more detailed texts are available for this purpose) and those test methods that should be applied for monitoring and cleanup of petroleum and petroleum products. As such, the book offers a ready guide to the many issues that are related to ecosystems as well as to pollutant mitigation and cleanup. 

The environmental movement is gaining acceptance and importance in many countries, particularly in those countries which have originated after the collapse of the former USSR.Many of these former Soviet Bloc countries have been left with a plethora of environmental problems arising from antiquated manufacturing processes. Built without pollution control equipment to problems arising from the careless disposal of chemicals and petroleum products, to disposal of excess military ordinance.

Polychlorinated biphenyls (PCBs), CFCs, petroleum products, and dioxin are major toxic contaminants in air (Section 3.3.2), soil (Section 3.5.3), and also in water. The readers are referred to Sections 3.3.2 and 3.5.3 for details about PCB characteristics, health effects, treatment technologies, and so on. For water quality management, they have been included in the list of the USEPA priority pollutants [86].
