Claim 30:
31. A process for separating a natural gas stream, the process comprising:
receiving a inlet fluid stream comprising natural gas into a plant upstream of a second fractionator;
receiving an input stream into a first fractionator, wherein the input stream comprises natural gas, and operating the first fractionator to fractionate the input stream, thereby forming a product stream and a first vapor effluent stream;
directing the first vapor effluent stream into the second fractionator;
operating the second fractionator to form a first liquid stream and a second vapor effluent stream; and
directing at least a portion of the first liquid stream into the first fractionator, wherein said at least a portion of the first liquid stream is fractionated as part of the input stream, and said product stream is formed;
further comprising, prior to directing at least a portion of the input stream into the first fractionator:
splitting the inlet fluid stream into multiple portions, the multiple portions including a portion directed into the second fractionator; and
cooling at least some of the multiple portions of the inlet fluid stream.
