Abstract
A process for recovery of C5+ hydrocarbons from a stripper gaseous hydroprocessed stream by contacting it with a stripper liquid stream. The stripper liquid stream absorbs C5+ hydrocarbons predominantly over other hydrocarbons thereby increasing C5+ yield and enabling the stripper gaseous stream to meet hydrocarbon limits. The rich absorbent stream may be sent to recovery with the stripper liquid from whence it came.
Claims19
A process for recovering hydrocarbons comprising:
- hydroprocessing a hydrocarbon feed stream in a hydroprocessing reactor to provide a hydroprocessed effluent stream;
- stripping a hydroprocessed stream taken from said hydroprocessed effluent stream to provide a stripper gaseous stream and a stripped liquid stream;
- and
- absorbing C5+ hydrocarbons from said stripper gaseous stream by contact with an absorbent stream to provide a C5+-rich absorbent stream, wherein said absorbent stream is taken from said stripped liquid stream.

A process for recovering hydrocarbons comprising:
- hydroprocessing a hydrocarbon feed stream in a hydroprocessing reactor to provide a hydroprocessed effluent stream;
- stripping a hydroprocessed stream taken from said hydroprocessed effluent stream to provide a stripper gaseous stream and a stripped liquid stream;
- condensing a stripper overhead stream;
- separating said stripper gaseous stream from a stripped liquid overhead stream;
- scrubbing acid gases from said stripper gaseous stream by contact with a solvent to provide a scrubbed stripper gaseous stream and
- absorbing C5+ hydrocarbons from said scrubbed stripper gaseous stream by contact with an absorbent stream taken from said stripped liquid stream to provide a rich absorbent stream.
