Method of manufacturing methanol |
摘要 |
A natural gas having steam and carbon dioxide added thereto is supplied into a reaction tube of a reformer provided with the reaction tube and a combustion radiation section for heating the reaction tube by combustion of a fuel so as to carry out a reaction between the hydrocarbon contained in the natural gas and the steam added to the natural gas, thereby forming a synthetic gas containing hydrogen, carbon monoxide and carbon dioxide. Then, the synthetic gas is subjected to a reaction in the presence of a methanol synthesizing catalyst. A crude methanol obtained is subjected to a gas-liquid separation. Further, a liquid crude methanol separated in the separation is distilled. In the particular methanol manufacturing process, a part of the purge gas obtained in the separation is recycled into the natural gas having steam and carbon dioxide added thereto in advance.
