Abstract
A gas separation apparatus comprises: at least two absorption beds respectively including an absorbent for absorbing certain gas; at least two three-way valves respectively installed on conduits for respectively connecting the absorption beds and outside of the apparatus; and a pump respectively connected to each end of the absorption beds and the three-way valves, for discharging gas absorbed by the absorbent and gas that is not absorbed by the absorbent. Gas that is absorbed by the absorbent and gas that is not absorbed by the absorbent are discharged by the single pump, thereby having a simple structure and reducing an installation space and a fabrication cost.
