The report describes a study of atmospheric emissions resulting from the manufacture of acetone and phenol from cumene. The air emissions from such manufacture consist only of hydrocarbons (HC). Emission factors are given for each species emitted to the atmosphere from each source within a typical plant. Emissions data are used to calculate several factors designed to quantify the hazard potential of the emissions. Industry contributions to atmospheric HC emissions from stationary sources are estimated to be: 0.023% for the Nation, 0.0049% for California, 0.013% for Illinois, 0.050% for Kansas, 0.084% for Louisiana, 0.034% for New Jersey, 0.049% for Ohio, 0.084% for Pennsylvania, and 0.081% for Texas. A variety of HC emission control methods are used, depending on the emission and the emission point. The two process technologies in use in the U.S. for oxidizing cumene to cumene hydroperoxide and for cleavage of the cumene hydroperoxide to acetone and phenol are discussed and compared. Process descriptions and flow sheets for these technologies are presented. Economic and production trends in the phenol industry and in the industries that use phenol, acetone, and the other byproducts are discussed and analyzed.
