Abstract
A method of manufacturing methanol comprises producing a synthesis gas, recovering carbon dioxide from combustion exhaust gas by a carbon dioxide recovery apparatus provided with a carbon dioxide absorption tower and a carbon dioxide-absorbing solution regenerating tower, feeding the carbon dioxide to the upstream side and/or the downstream side of a reformer, allowing reaction of the synthesis gas to produce a reaction product, recovering a liquid crude methanol, and distilling the liquid crude methanol in a distillation apparatus provided with a topping tower, a pressure distillation tower and an atmospheric distillation tower to isolate refined methanol. Bottom liquid of the topping tower is heated and introduced into the pressure distillation tower, and the heat of distilled liquid discharged from this tower is utilized as a heat source for the regenerating tower and as a heat source for the atmospheric distillation tower.
