Evaluation of Benzene-Related Petroleum Processing Operations

摘要

This report describes refinery processing of liquids with high benzene concentrations. Processes which are addressed include aromatics extraction (both sulfolane and glycol solvent processes), toluene dealkylation, and toluene disproportionation. Each process is described and modeled. In addition, a list and characterization of the 45 plants in the United States processing liquids with high benzene concentrations is presented. Characteristics include, where possible, company name, plant location, benzene process, and benzene production rate.
