Summary: | The invention belongs to the technical field of gas separation, and particularly relates to a method and a device for guaranteeing field operation power and carbon dioxide supply. The method comprises the following steps: firstly, taking field resource methanol and a water source as raw materials, generating a mixed gas of hydrogen and carbon dioxide through a methanol/water reforming process; then, extracting pure hydrogen from the mixed gas by adopting a membrane separator, and outputting electric power by a hydrogen/air fuel cell so as to meet the electric power requirement of field site construction; meanwhile, using a carbon dioxide purification process based on a pressure swing adsorption technology, and extracting high-purity carbon dioxide gas from the mixed gas; and then liquefying the high-purity carbon dioxide gas into liquid carbon dioxide through pressurization so that the carbon dioxide requirement required by field site construction is met. The raw materials are wide in source, low in price and |
