Abstract
A start-up method of a fractionator which fractionally distills FT synthesized hydrocarbons produced by the Fischer-Tropsch synthesis reaction, the method includes: 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 the outside; cooling down the light FT synthesized hydrocarbons discharged from the FT reactor for liquefaction; supplying the liquefied light FT synthesized hydrocarbons to the fractionator; and heating the light FT synthesized hydrocarbons and circulating the light FT synthesized hydrocarbons to the fractionator.
