ABSTRACT:
A process to reduce emissions discharged from a natural gas processing system wherein the processing system includes a glycol dehydrator for absorbing water, moisture and absorbable hydrocarbons, a reboiler for heating water rich glycol, a still column in communication with the reboiler and a reflux condenser. The process includes the steps of directing vapors and gases from the still column and reflux condenser to a condenser in order to condense vapors to liquid. The gases and liquids from the condenser are directed to a condensate separator in order to separate by gravity. Non-condensible vapors and water from the condensate separator are delivered to a vaporization chamber immersed in the reboiler. Water is re-vaporized into steam and permitted to mix with non-condensible vapors in the vaporization chamber. The steam and non-condensible vapors are inducted into a combustion zone in a firetube in the reboiler. The hydrocarbons in the vapors are combusted in the firetube.
