Abstract: The C2 hydrogenation charging system is renovated through adding a temperature regulating cross-line in the process side of the feed cooler of the C2 hydrogenation reactor.The control mode of anti-surge valve in the fifth stage of cracking gas compressor is optimized to meet the requirement of the reactor at the initial stage of start-up when the feed amount is low.Through such renovation and the optimization of start-up control mode,the steam consumption of the feed heater in the C2 hydrogenation reactor is reduced,and the time needed by acetylene at the outlet of the C2 hydrogenation reactor reaching qualification is shortened.
