"This report summarizes literature on hazardous/toxic air pollutant (HAP) sources and control techniques employed in their reduction and/or destruction. The information was abstracted from an extensive computerized and manual literature search and data base development study. The primary emphasis of the report is on HAP control technology. However, a brief summary of major source categories that emit HAPs is also included. About 70 hazardous/toxic compounds or groups of compounds are covered in this study; most are volatile organic compounds. In the HAP control technology data base, most of the information is for the Synthetic Organic Chemical Manufacturing Industry (SOCMI) source category. However, data also are available for the combustion, solvent use, and metal processing industries. The major add-on control techniques for volatile organic HAPs discussed in this report are combustion, absorption, adsorption, and condensation. Combustion techniques include thermal and catalytic incineration, flaring, and disposal of waste streams in boilers and process heaters. The add-on control devices identified in the literature for control of particulate HAP emissions are electrostatic precipitators, baghouses, wet scrubbers, and cyclones. A list of references identified during this study, along with abstracts of those references, is included in the Bibliography section of the full report." |
