syngas manufacturing method and device for Fischer-Tropsch process using natural gas

摘要

PURPOSE: A manufacturing method of synthetic gas for final test process by a compact separation process and a device thereof are provided to be applied in a small and medium GTL (gas to liquid) process, to be compacted and to enhance efficiencies. CONSTITUTION: A manufacturing method of synthetic gas for final test process comprises the following steps: (50) reforming raw gas into synthetic gas which contains carbon monoxide and hydrogen; (52) cooling the synthetic gas; (54) steam isolation step which removes moisture only from frozen synthetic gas; and (56) partially isolating and filtering hydrogen from the synthetic gas in which moisture is removed. The hydrogen isolated from the hydrogen isolation step is used as fuel for the reformation reaction in the reformation reaction step.
