  • Process for recovering hydrocarbon from hydroprocessed gaseous stream
    Patent number: 11028331
    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.
