Abstract:
A method of manufacturing methanol, comprising the steps of:supplying a raw material gas containing hydrocarbon as a main component and steam into a reformer, said raw material gas being supplied into said reformer through a moistening device, to carry out reaction between said hydrocarbon and steam to form a synthetic gas containing as main components hydrogen, carbon monoxide, and carbon dioxide;performing reaction of said synthetic gas in the presence of a methanol synthesizing catalyst to synthesize a crude methanol; anddistilling a liquid crude methanol recovered in said synthesizing process to separate the crude methanol into a waste liquid material and a refined methanol, said waste liquid material containing low boiling point organic compounds and high boiling point organic compounds,wherein carbon dioxide is supplied to at least one fluid passageway selected from the group consisting of a fluid passageway positioned upstream of said moistening device and another fluid passageway interposed between the moistening device and said reformer.
