摘要：This invention provides a process for the production of methanol whichcomprises steps of
(a) reacting hydrocarbon with steam to generate synthesis gas composed ofhydrogen, carbon monoxide and carbon dioxide as main components,
(b) reacting the synthesis gas on a methanol synthesis catalyst to synthesize crudemethanol, and
(c) feeding the resultant crude methanol directly to a distillation column and distillingthe crude methanol to separate prified methanol and an effluent water containing all orpart of low boiling organic compounds, high boiling organic compounds and organicacids,
the above step (c) being a step for the distillation and separation carried out withoutadding any alkali compound to neutralize the organic acids in the crude methanolobtained in the above step (b),
the process including a step of bringing the effluent water resulting from the abovestep (c) into contact with gaseous hydrocarbon to humidify the hydrocarbon,< P>
the humidified hydrocarbon being used as a material for hydrocarbon and steam used
in the above step (a).
