A method for producing methanol includes purifying converter gas; mixing purified converter gas with coke oven gas to obtain mixed gas; and using the reaction of the mixed gas to produce methanol. By the method and device for producing methanol disclosed by the present application, the converter gas from the by-product gas produced by steelmaking process is purified in order to mix with the coke oven gas produced by coking process at a suitable proportion. The mixed gas is desulfurated and converted to obtain synthesis gas, where the ratio of hydrogen and carbon conforms to the requirement of theoretical value. The method increases use ratio of useful elements in the raw material, enhances production efficiency, reduces pollution from waste gas to the environment, decreases production cost and increases economic benefit. |
