TECHNOLOGIES FOR COMPREHENSIVE UTILIZATION OF REFINERY GAS

Sinopec Technological

Open publisher page 0 citations

Abstract

Domestic developed technologies for utilization of hydrogen, ethylene, propylene and butylenes in refinery gas are reviewed. These technologies are: hydrogen separation from FCC dry gas with membrane; coker gas hydrotreating for preparing feedstock of steam reforming; ethylbenzene alkylation from FCC dry gas without pretreating; polypropylene, acrylonitrile and isopropyl alcohol productions from propylene; and MTBE, butadiene, isobutylene and methyl ethyl ketone manufacturing from butylenes. Further comprehensive utilization of refinery gas for products with high additional values is still urgently needed.
