Proceedings of the Gas Research Institute Glycol Dehydrator Air EmissionsConference. Held in New Orleans, Louisiana on July 20-22, 1992

摘要

Emissions of benzene, toluene, ethyl benzene, and the xylene isomers (BTEX) andother volatile organic compounds (VOC) from the reboiler still vent of glycol dehydration units have become a major concern for the natural gas industry as a result of increasing regulatory pressure. The Clean Air Act Amendments of 1990 have provided an impetus for regulating these emissions, and several states are regulating or considering regulation of these units. Because the estimated 20,000-30,000 glycol units in the United States treat virtually all of the domestically produced gas, this issue is of crucial importance to the natural gas industry. To encourage communication and a transfer of regulatory and technical information, the Gas Research Institute sponsored a two and a half day conference on glycol dehydrator air emissions issues. Twenty-two technical papers were presented on regulatory issues and activities, industry approaches to addressing emissions, research and development programs, process and emissions modeling, and control technologies.
