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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The process of claim 1 wherein C5+ hydrocarbons are a predominant material absorbed from the stripper gaseous stream in the rich absorbent stream. ### Claim 3 (depends on 1) The process of claim 1 wherein said stripping step comprises condensing a stripper overhead stream and separating said stripper gaseous stream from a stripped liquid overhead stream. ### Claim 4 (depends on 1) The process of claim 1 further comprising 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. ### Claim 5 (depends on 3) The process of claim 3 further comprising washing amines from said scrubbed stripper gaseous stream to provide a washed, scrubbed stripper gaseous stream and absorbing C5+ hydrocarbons from said washed, scrubbed stripper gaseous stream. ### Claim 6 (depends on 1) The process of claim 1 further comprising adding said rich absorbent stream to said stripped liquid stream. ### Claim 7 (depends on 6) The process of claim 6 further comprising splitting said stripped liquid stream into an absorbent stream and a remaining stripped liquid stream and said rich absorbent stream is added to said remaining liquid stream. ### Claim 8 (depends on 1) The process of claim 1 further comprising separating said hydroprocessed effluent stream in a separation section comprising a separator to provide a separated liquid hydroprocessed stream comprising said hydroprocessed stream and a separated gaseous hydroprocessed stream. ### Claim 9 (depends on 8) The process of claim 8 wherein said separation step further comprises separating a process stream taken from said hydroprocessed effluent stream in a separator to provide a separated gaseous hydroprocessed stream and a separated liquid hydroprocessed stream and taking said hydroprocessed stream from said separated liquid hydroprocessed stream. ### Claim 10 (depends on 9) The process of claim 9 wherein said separation step further comprises separating said hydroprocessed effluent stream in a hot separator to provide a hot separated liquid hydroprocessed stream and a hot separated gaseous stream comprising said process stream taken from said hydroprocessed effluent stream. ### Claim 11 (depends on 1) The process of claim 1, further comprising at least one of: sensing at least one parameter of the process, and generating or transmitting a signal or data from the sensing. ### Claim 12 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. ### Claim 13 (depends on 12) The process of claim 12 wherein Cb 5+ hydrocarbons are a predominant material absorbed from the stripper gaseous stream in the rich absorbent stream. ### Claim 14 (depends on 12) The process of claim 12 further comprising washing amines from said scrubbed stripper gaseous stream to provide a washed, scrubbed stripper gaseous stream and absorbing C5+ hydrocarbons from said washed, scrubbed stripper gaseous stream. ### Claim 15 (depends on 12) The process of claim 12 further comprising adding said rich absorbent stream to said stripped liquid stream. ### Claim 16 (depends on 15) The process of claim 15 further comprising splitting said stripped liquid stream into an absorbent stream and a remaining stripped liquid stream and said rich absorbent stream is added to said remaining liquid stream. ### Claim 17 (depends on 12) The process of claim 12 further comprising separating said hydroprocessed effluent stream in a separation section comprising a separator to provide a separated liquid hydroprocessed stream comprising said hydroprocessed stream and a separated gaseous hydroprocessed stream. ### Claim 18 (depends on 17) The process of claim 17 wherein said separation step further comprises: separating said hydroprocessed effluent stream in a hot separator to provide a hot separated liquid hydroprocessed stream and a hot separated gaseous hydroprocessed stream; separating said hot separated gaseous hydroprocessed stream in a cold separator to provide a cold separated gaseous hydroprocessed stream and a cold separated liquid hydroprocessed stream and taking said hydroprocessed stream from said cold separated liquid hydroprocessed stream. ### Claim 19 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 taken from said stripped liquid stream to provide a rich absorbent stream, wherein C5+ hydrocarbons are a predominant material absorbed from the stripper gaseous stream in the rich absorbent stream.
