Abstract
A process for recovering liquid hydrocarbons from a gaseous stream containing the liquid hydrocarbons, the process comprising (a) providing a dehydrated gaseous stream including carbon dioxide, methane, ethane, propane, and C4 and heavier hydrocarbons; (b) cooling the dehydrated gaseous stream to form a condensate stream including C4 and heavier hydrocarbons; (c) separating at least a portion of the carbon dioxide, methane and ethane from the condensate stream; and (d) distilling the condensate stream to thereby form a liquid hydrocarbon stream.

A process for recovering liquid hydrocarbons from a gaseous stream containing the liquid hydrocarbons, the process comprising:
- (a) providing a dehydrated gaseous stream including carbon dioxide, methane, ethane, propane, and C4 and heavier hydrocarbons;
- (b) cooling the dehydrated gaseous stream to form a condensate stream including C4 and heavier hydrocarbons;
- (c) separating at least a portion of the carbon dioxide, methane and ethane from the condensate stream;
- and
- (d) distilling the condensate stream to thereby form a liquid hydrocarbon stream.
A method for recovering liquid hydrocarbons from a gaseous stream containing the liquid hydrocarbons, the process comprising:
- (a) providing a hydrated gaseous stream including water, carbon dioxide, methane, ethane, propane, and C4 and heavier hydrocarbons;
- (b) cooling the hydrated gaseous stream to condense a portion of the water within the hydrated gaseous stream to thereby form a cooled hydrated gaseous stream;
- (c) separating the condensed water from the cooled hydrated gaseous stream to provide a partially dehydrated stream;
- (d) dehydrating the partially dehydrated stream to provide a dehydrated gaseous stream including carbon dioxide, methane, ethane, propane, and C4 and higher hydrocarbon;
- (e) cooling the dehydrated gaseous stream to thereby form a condensate stream including C4 and heavier hydrocarbons;
- (f) separating a portion of the carbon dioxide, methane, ethane, and propane from the condensate stream;
- and
- (g) distilling the condensate stream to thereby form a liquid hydrocarbon stream.
