| Abstract: | This article introduces and analyzes the interlock system status and problems of the existing delayed coker unit,including furnace system,hydraulic cutting system,compressor system,heat pump and LPG pump system,as well as the switch valve system. It also proposes the design ideas on sequence logic system of coke drum operation,sequence interlock of furnace start-up operation,interlock between the isolation valve on the discharge of coke drum relief valve and the vent valve,along with LL level interlock of t... |
