Atmospheric Rich/Lean (ARL) Method for Determining Glycol Dehydrator Emissions

In this program, the atmospheric rich/lean sampling and analytical method (ARL method) was used to determine the emissions from the regenerator still vent of triethylene glycol (TEG) dehydrators of natural gas.

Summary:
Increasingly stringent environmental regulations have caused the natural gas industry to be concerned about air emissions from natural gas dehydrators. Of particular concern are emissions of benzene, toluene, ethylbenzene, and xylenes (BTEX) and other volatile organic compounds (VOCs). In this program, the atmospheric rich/lean sampling and analytical method (ARL method) was used to determine the emissions from the regenerator still vent of triethylene glycol (TEG) dehydrators of natural gas. The ARL method was extensively field-tested at ten sites. The method uses the difference between concentrations in the rich and lean glycols along with the glycol circulation rate to determine the emissions of individual compounds. The method was determined to be cost-effective, accurate, and easy-to-use, and was also found acceptable for determining VOC emissions from units with flash tanks and without stripping gas. An appendix contains the Environmental Protection Agency's memorandum on the glycol dehydrator emissions test report and emissions estimation methodology.
