PROCESS FOR RECOVERY AND PURIFICATION OF C.SUB.3- C IN4 XXHYDROCARBONS USING SEGREGATED PHASE SEPARATION AND DEPHLEGMATION

ABSTRACT A low temperature phase separation, dephlegmation and distillation process is described for resolving a light hydrocarbon gas stream to recover and purify C3+ and/or C4+ hydrocarbons. The phase separation bottoms stream is segregated from the dephlegmation bottoms stream and both streams ar...

Zusammenfassung:ABSTRACT A low temperature phase separation, dephlegmation and distillation process is described for resolving a light hydrocarbon gas stream to recover and purify C3+ and/or C4+ hydrocarbons. The phase separation bottoms stream is segregated from the dephlegmation bottoms stream and both streams are expanded to produce refrigeration for the feed stream. Both streams are then separately introduced into a distillation column for final purification of the heavy hydrocarbon product.
