Management of Air Emissions from Glycol Dehydrators in Canada

摘要

Glycol dehydrators are used to remove water from natural gas, and to prevent hydrates and corrosion in natural gas pipelines. There are an estimated 3,500 glycol dehydrators installed at gas from glycol dehydrators may include greenhouse gases, VOC's, aromatic hydrocarbons, and hydrogen sulphide. New criteria for controlling benzene emissions from glycol dehydrators in Canada are expected to be published in late 1997.
