ABSTRACT:
A method and system for reducing emissions from glycol dehydrators which employ a vapor-liquid contactor operated under ambient conditions to treat the organic vapors and liquids exiting from a condenser attached to the vapor vent of the glycol reboiler. A stream of the organic liquids is passed to the top of the contactor and allowed to descend in counter-current relation to the upward moving gas introduced at the bottom portion of the contactor. Liquids containing a relatively high content of hydrocarbons may be recovered from the bottom of the contactor, and vapors having a reduced content of organic emissions can be emitted directly to the atmosphere from the top the contactor.
