A method for producing methanol includes obtaining reformed gas by subjecting raw material gas containing methane to partial oxidation reforming by use of oxygen; reducing a CO/COratio in the reformed gas; and obtaining produced gas containing methanol from the reformed gas with the reduced CO/COratio by using any of a fixed-bed reactor and an isothermal reactor.

System and method for producing methanol

A denitrator removes nitrogen oxide in a flue gas generated from a combustion furnace by injecting a reducing agent into the flue gas. The denitrator includes a housing disposed above the combustion furnace. The housing includes a discharge port for the flue gas at one end of the housing. A cross-sectional area of flow of the flue gas gradually increases toward the discharge port. The housing gathers and guides the flue gas to the discharge port. The denitrator injects the reducing agent in another end of the housing.

Included are an ammonia synthesis column that synthesizes ammonia from a raw material gas, a discharge line that discharges a synthetic gas, a water-cooled cooler that cools the synthetic gas with a coolant, disposed in the discharge line, an ammonia separator into which a synthetic gas after cooling is introduced and which separates the ammonia gas and a liquid ammonia from each other, a raw material return line that returns a raw material gas containing the separated ammonia gas to the ammonia synthesis column side as a return raw material gas, and a compressor that compresses the return raw material gas, disposed in the raw material return line. An ammonia concentration in the return raw material gas is 5 mol % or more, and an ammonia synthesis catalyst that synthesizes the ammonia gas in the ammonia synthesis column is a ruthenium catalyst.
