Abstract:
1. A process to reduce emissions discharge from a natural gas processing system, wherein said processing system includes a glycol dehydrator for absorbing water, moisture and absorbable hydrocarbons, a reboiler for heating water rich glycol to produce vapors, a still column in communication with said reboiler, and a reflux condenser, which process comprises: directing vapors and gases from said still column and said reflux condenser to a condenser in order to condense vapors to liquid; directing gases and liquids from said condenser to a condensate separator in order to separate by gravity; removing hydrocarbon liquids from said condensate separator; delivering non-condensible vapors and water from said condensate separator to a vaporization chamber immersed in said reboiler; revaporizing said water into steam and permitting mixing with said non-condensible vapors in said vaporization chamber; inducting said steam and non-condensible vapors into a combustion zone in a firetube in said reboiler; and combusting hydrocarbons contained in said vapors in said firetube.
