Claim 8:
9. The process of claim 1, further comprising, prior to directing the first vapor effluent stream into the second fractionator:
directing the second portion of the first vapor effluent stream through a heat exchanger, and then directing the second portion of the first vapor effluent stream into the second fractionator;
combining the first portion of the first vapor effluent stream with a first 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, wherein the first combined stream and the second portion are fractionated within the second fractionator to form the first liquid stream and the second vapor effluent stream;
directing a second portion of the inlet fluid stream through the heat exchanger, wherein the second portion of the first vapor effluent stream, the first portion of the inlet fluid stream, and the second portion of the inlet fluid stream are passed in thermal communication within the heat exchanger; and
directing the second portion of the inlet fluid stream into the first fractionator.
