Abstract
A gas separation and recovery method is provided. Based on the fact that a gas adsorbent has differing adsorption and desorption characteristics depending on the affinities and pressures of gas species, and gases of different species are desorbed at different timings, a target gas component is separated and recovered from a source gas by a pressure swing adsorption process in such a manner that a desorption step is divided into, for example, two time periods and desorbed gases are recovered separately in the respective time periods. In this manner, when gasand gashaving different desorption timings are adsorbed to an adsorbent, a gas rich in gas, and a gas rich in gasmay be recovered separately from each other. Thus, it becomes possible to separate and recover selectively a target gas component with high concentration.
