摘要： A raw material gas containing hydrocarbon as a main component is supplied together with steam to a reformer (20) through a moistening device (10) to form a synthetic gas containing hydrogen, carbon monoxide and carbon dioxide as main components by the reaction between the hydrocarbon contained in the raw material gas and the steam. In forming the synthetic gas, carbon dioxide is supplied to at least one fluid passageway selected from the group consisting of the fluid passageway (306) positioned upstream of the moistening device (10) and the fluid passageway (301) interposed between the moistening device (10) and the reformer (20). As a result, the excess hydrogen contained in the gas formed in the reformer (20) is effectively utilized without bringing about deactivation of the methanol synthesizing catalyst in the methanol synthesizing step. Also, carbon dioxide is effectively utilized to decrease the amount of carbon dioxide discharged to the outside of the system. Further, it is possible to decrease the amount of steam supplied to the reformer (20).

摘要： A method of manufacturing methanol comprising reacting hydrocarbons with water vapor in a reformer (10) to produce a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide, allowing reaction of the synthesis gas to take place over a methanol-synthesizing catalyst to produce a crude methanol, cooling the crude methanol, separating the cooled crude methanol into unreacted gas and liquid crude methanol, and distilling the liquid crude methanol to separate it into refined methanol and waste water containing low boiling point organic compounds and high boiling point organic compounds. Carbon dioxide in combustion exhaust gas to be discharged from the reformer (10) is recovered in a carbon dioxide-recovering device, and that in feeding the carbon dioxide thus recovered to the upstream side and/or the downstream side of the reformer (10), part of the unreacted gas is utilized as a purge gas, a portion of which being utilized as a fuel for a combustion device (12) of the reformer (10), while the balance of the purge gas being utilized as a fuel for other heating sources and/or as an agent for desulfurizating raw gas.

摘要： A method of manufacturing methanol comprising reacting hydrocarbons with water vapor in a reformer (30) to produce a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide, recovering carbon dioxide from combustion exhaust gas which has been discharged from the reformer (30) by a carbon dioxide recovery apparatus (90) provided with a carbon dioxide absorption tower and with a carbon dioxide-absorbing solution regenerating tower, feeding the carbon dioxide thus recovered to the upstream side and/or the downstream side of the reformer (30), allowing reaction of the synthesis gas to take place over a catalyst to produce a reaction product, recovering liquid crude methanol from the reaction product, distilling the liquid crude methanol in a distillation apparatus (80) provided with a pressure distillation tower and with an atmospheric distillation tower to separate it into refined methanol and waste water containing low boiling point organic compounds and high boiling point organic compounds. Bottom liquid in a topping tower of the distillation apparatus (80) is heated and introduced into the pressure distillation tower in the distillation step, and the heat of distilled liquid discharged from the top of the pressure distillation tower is utilized as a heat source for the carbon dioxide-absorbing solution regenerating tower (93) and as a heat source for the atmospheric distillation tower.
