GAS-ADSORBING SEPARATION EQUIPMENT

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 .
