SEPARATION OF AROMATICS WITH PERVAPORATION MEMBRANE

Methods and apparatus relate to separating and removing aromatic compounds from a hydrocarbon stream. Splitting of the hydrocarbon stream into constituents as desired relies on a membrane and distillation columns that supply feed into the membrane and receive retentate and permeate streams output fr...

Zusammenfassung:	Methods and apparatus relate to separating and removing aromatic compounds from a hydrocarbon stream. Splitting of the hydrocarbon stream into constituents as desired relies on a membrane and distillation columns that supply feed into the membrane and receive retentate and permeate streams output from the membrane. Configurations employing the membrane and the distillation columns enable benzene recovery and facilitate efficient separation.
