Hydrocarbon synthesis reaction apparatus, start-up process thereof, and hydrocarbon synthesis reaction system

摘要

This hydrocarbon synthesis reaction device comprises: a synthetic gas supply passage for supplying a synthetic gas compressed by a first compressor; a reaction vessel for containing a catalyst slurry; a gas-liquid separator for gas-liquid separating unreacted synthetic gas and hydrocarbon derived from the reaction vessel; a first recirculation passage for recirculating the unreacted synthetic gas after the gas-liquid separation compressed by a second compressor to the reaction vessel; and a second recirculation passage for recirculating the rest of the unreacted synthetic gas after the gas-liquid separation to a suction side of the first compressor at the time of start up operation when the introduction amount of the synthetic gas is gradually increased.
