摘要:
A gas adsorption separation apparatus includes a plurality of adsorption vessels through which a gas mixture is passed to be brought into contact with an adsorbent to adsorb at least one gas component in the gas mixture, the plurality of adsorption vessels performing, by turns, an adsorption step and a desorption step, or an adsorption step, a rinsing step and a desorption step, wherein each adsorption vessel has a vertical cylindrical shape, the interior of each adsorption vessel is divided into five regions in parallel in a horizontal direction, and of these regions, a central region constitutes a gas inflow region A, regions adjacent to the gas inflow region A on opposite sides thereof constitute gas adsorption regions B 1 and B 2 , and outermost regions adjacent to the respective gas adsorption regions B 1 and B 2 constitute off-gas outflow regions C 1 and C 2 .

A blast furnace gas discharged from a blast furnace is separated into gases containing various components using two-stage gas separation and refinement apparatuses. First, the blast furnace gas is separated into a gas containing H 2 , N 2 , and an unavoidable impurity gas component, a gas containing N 2 and an unavoidable impurity gas component, a gas containing N 2 , CO, CO 2 , and an unavoidable impurity gas component, and a gas containing CO, CO 2 , and an unavoidable impurity gas component with a gas separation and refinement apparatus of a first stage. Then, of these separated gases, the gas containing CO, CO 2 , and the unavoidable impurity gas component is separated into a gas containing CO and an unavoidable impurity gas component, a gas containing CO 2 and an unavoidable impurity gas component, and a gas containing CO, CO 2 , and an unavoidable impurity gas component with a gas separation and refinement apparatus of a second stage.

摘要:
A method for treating drain in hydrogen production includes steps of gasifying in a gasifier (1), reforming in a reformer (2), gas-liquid separation in a gas-liquid separator (4), PSA gas separation in a PSA separator (5) and evaporation in a drain treatment unit (6). In the gasifying, a mixed material containing methanol is heated and gasified. In the reforming, reformed gas containing hydrogen is produced from the mixed material by reforming reaction of methanol. In the gas-liquid separation, a liquid component is separated from the reformed gas and discharged as drain. In the PSA gas separation, hydrogen-rich gas and offgas are extracted from the reformed gas by PSA separation using an adsorption tower. In the gasifying, the offgas is burned, and the mixed material is heated by using the combustion gas as heat source. In the evaporation, drain is evaporated using the combustion gas after heating the mixed material as heat source.
