ABSTRACT:
A method for decreasing the external energy input to a fractionation system is disclosed. The method utilizes a compression zone communicating with either the overhead fraction or the bottoms fraction from a fractionation zone. The method is directed at regulating the rate of energy addition and/or removal to the fractionation zone by at least one of the fractions returned to the fractionation zone to maintain the separated fractions within the desired limits.
