STARTING-UP METHOD OF FRACTIONATOR

摘要

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 (30) PERFORMING THE FISCHER-TROPSCH SYNTHESIS REACTION FROM THE FT REACTOR (30) TO THE OUTSIDE; COOLING DOWN THE LIGHT FT SYNTHESIZED HYDROCARBONS DISCHARGED FROM THE FT REACTOR (30) 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.
