ABSTRACT:
A process for purifying a raw natural gas stream is provided by contacting the gas stream with an absorbant to remove water and hydrocarbon impurities, separating the water and hydrocarbon impurities and absorbant from the gas stream, separating the absorbant from the water and hydrocarbon impurities to provide a liquid absorbant stream and a water vapor and hydrocarbon vapor stream, condensing the water vapor and a portion of the hydrocarbon vapor stream to provide a mixed liquid/vapor stream, passing the mixed stream through a pump capable of pumping a mixed stream, and disposing of the thus-reduced volume, higher pressure, mixed stream. One aspect of the invention provides for the reintroduction of the mixed stream to the process with the raw natural gas, thereby eliminating volatile organic compound disposal concerns.
