Abstract:
A process of degasolining and dehydrating a charge of a hydrocarbon gas containing H.sub.2 O, a gasoline fraction and a C.sub.1-4 hydrocarbon fraction, comprising the steps of:a) adding methanol to said gas;b) refrigerating the gas to condense a liquid aqueous phase containing methanol, a hydrocarbon liquid phase containing methanol and a degasolined gas phase;c) separating said three phases in a triphasic separating zone;d) passing the separated liquid hydrocarbon phase containing methanol into a stabilization zone so as to separate a light gas fraction methane and ethane at the top of said zone and to discharge a hydrocarbon liquid phase containing methanol at the bottom of said stabilization zone;e) separating methanol from the discharged hydrocarbon containing methanol liquid phase and recovering said hydrocarbon liquid phase as gasoline;f) contacting said degasolined gas phase with a hydrocarbon liquid fraction to recover methanol from said gas phase; andg) passing the resultant hydrocarbon liquid fraction containing methanol to said stabilization zone.
