Abstract
Volatile organic compounds are removed from crude oil by adding heat upstream of a vapor recovery tower. The heat input may either be sufficient to break the emulsion as in a here treater or extra heat may be added to stabilize the crude oil. Produced gas may be recovered as NGL in one or more cooling stages. Produced gas, whether partially recovered or not, may be used as fuel for said heater treater, other combustion device or compressed into a pipeline.
