Claim 5:
6. The process of claim 1, further comprising, prior to directing the first vapor effluent stream into the second fractionator:
receiving an inlet fluid stream comprising natural gas upstream of the second fractionator,
directing the second portion of the first vapor effluent stream and at least a portion of the inlet fluid stream comprising the natural gas through a heat exchanger, wherein the second portion of the first vapor effluent stream and the portion of the at least a portion of the inlet fluid stream comprising the natural gas are in thermal communication within the heat exchanger;
combining the first portion of the first vapor effluent stream with the at least a portion of the inlet fluid stream comprising the natural gas exiting the heat exchanger to form a first combined stream, and directing the first combined stream into the second fractionator; and
directing the second portion of the first vapor effluent stream into the second fractionator, wherein the first combined stream and the second portion of the first vapor effluent stream are fractionated within the second fractionator to form the first liquid stream and the second vapor effluent stream.
