ABSTRACT:
The present invention is a set of improvements in deethanizing and depropanizing fractionation steps in NGL processing. The several embodiments of the present invention apply component distribution to multiple columns, interreboiling, intercondensing, thermal coupling and "thermo-mechanical" coupling to the commonly practiced deethanizer/depropanizer fractionation sequence of NGL processing.
