US Patent:

54535590, Sep 26, 1995

Filed:

Apr 1, 1994

Appl. No.:

8/221616

Inventors:

Christopher L. Phillips - Houston TX
Vijender K. Verma - Sugar Land TX

Assignee:

The M. W. Kellogg Company - Houston TX

International Classification:

C07C 700
F25J 302

US Classification:

585809

Abstract:

A hybrid condensation-absorption process and unit is disclosed for the recovery of olefins. A mixed-component stream containing hydrogen, methane and olefins is compressed and refrigerated against propylene refrigerant to partially condense the stream. The condensate is stripped of volatile components and fed to a fractionation unit such as a deethanizer. The volatile components stripped from the condensate and the non-condensed vapor from the mixed-component stream are fed to a solvent absorption unit to remove olefins which are absorbed in the solvent. The olefins-rich solvent is regenerated to recover olefins and lean solvent. The lean solvent is recirculated to the absorption unit. The olefins recovered from regeneration of the solvent are fed to the fractionation unit along with the pre-stripped condensate. Vapor from the absorption unit is cryogenically processed to recover a crude hydrogen product, a fuel gas product and residual olefins which can be recycled to the absorption unit.
