NAPHTHA PRODUCTION FROM REFINERY FUEL GAS

摘要

Systems and methods are provided for upgrading refinery fuel gas and/or production of naphtha from refinery fuel gas. Initially, an olefin-containing feed can be exposed to conventional conditions for removing a portion of C₃+ compounds and a portion of sulfur-containing compounds. The olefin-containing feed can then be exposed to conversion conditions for the oligomerization of olefins present in the olefin-containing feed, producing an effluent that includes C₅+ olefins. The C₅+ olefins can be removed from the effluent, and the effluent can then be subjected to an amine wash to remove sulfur- containing compounds. The resulting product effluent includes a refinery fuel gas product having a controlled energy content.
