Abstract: This paper explores the optimization schemes for existing revamping projects of offshore torch gas recovery. Based on the experience of offshore torch gas recovery projects,the on-site equipment and system configurations of two projects are analyzed and optimized by focusing on key aspects including core equipment,instrument configuration,central control integration,and construction safety,so as to reduce the investment in offshore torch gas recovery projects and improve the safety of the recovery system.

Key words: flare gas recovery unit, compressor, water seal tank, safety valve group, programmable logic controller, production process control system, emergency shutdown system
