METHOD FOR CONTROLLING MIXING IN OF METAL IN APPARATUS FOR MANUFACTURING SYNTHETIC GAS

摘要

PROBLEM TO BE SOLVED: To prevent mixing in of metal components in an apparatus (reformer) for manufacturing synthetic gas used in a GTL (gas-to-liquid) synthetic gas manufacturing step.

SOLUTION: Provided is a method for controlling mixing in of metal in an apparatus for manufacturing synthetic gas in a GTL process that includes a synthetic gas manufacturing step in which synthetic gas is manufactured by a reforming reaction for natural gas and gas that includes steam and/or carbon dioxide in the apparatus for manufacturing synthetic gas. The method for controlling mixing in of metal in the apparatus for manufacturing synthetic gas is characterized by the carbon dioxide in the synthetic gas manufactured in the synthetic gas manufacturing step, being separated and recovered and, when the separated and recovered carbon dioxide gas is recycled into the starting material gas for the reforming reaction in the synthetic gas manufacturing step, the nickel concentration in the recycled carbon dioxide gas is ≤0.05 ppmv.
