METHOD OF REMOVING HEAVY HYDROCARBONS

摘要

In the present invention, when an FT off-gas is used as fuel for a tubular reformer in a GTL process, blockage of a heating burner tip by deposition of a heavy hydrocarbon contained in FT off-gas is prevented. The heavy hydrocarbon contained in FT off-gas is removed by being put into contact with absorber oil, introduced into a distillation column, and aerated with a coolant or an absorbent, and the FT off-gas from which the heavy hydrocarbon has been removed is used as fuel for the tubular reformer. With this configuration, prolonged stable operation of the tubular reformer becomes possible and effective use of the FT off-gas as a fuel can be ensured.
