ABSTRACT
Air pollutants produced by petrochemical manufacturing practices include sulfur oxides, nitrogen oxides, carbon monoxide, particulates, odors, and a wide variety of hydrocarbons. The US Environment protection act (EPA) in an attempt to determine the significance of air pollution from the petrochemical industry conducted a study to determine industry descriptions, air emission control problems, sources of air emissions, statistics on quantities and types of emissions, and descriptions of emission control devices used. A survey of the air pollution control techniques used in the petrochemical industry in India, along with gaseous pollutant regulations and monitoring techniques, may be found in an article by N. G. Ashar. Treatment of waste air from three air oxidation processes by incineration achieved high removals of hydrocarbon contamination. D. A. Max and S. T. Jones reported on an operation technique that not only reduced air emissions but reduced production costs at an ethylene plant. Control of air pollutants emitted from controlled sources has been well studied.
