Abstract:
1. A start-up method of a fractionator which fractionally distills FT synthesized hydrocarbons produced by the Fischer-Tropsch synthesis reaction, the method comprising: discharging light FT synthesized hydrocarbons which exist in a gaseous state in an FT reactor performing the Fischer-Tropsch synthesis reaction from the FT reactor to a vapor-liquid separator; cooling down the light FT synthesized hydrocarbons discharged from the FT reactor for liquefaction; supplying the liquefied light FT synthesized hydrocarbons to the fractionator; heating the liquefied light FT synthesized hydrocarbons; and circulating the heated light FT synthesized hydrocarbons to the fractionator via a circulating line, thereby heating the fractionator.
