Title: FULL-TEMPERATURE-RANGE PRESSURE SWING ADSORPTION GAS SEPARATION, REFINEMENT AND PURIFICATION METHOD
Abstract:
A full-temperature-range pressure swing adsorption gas separation, refinement and purification method, comprising the following processes to be carried out sequentially: 1) a pressure swing adsorption concentration process: introducing raw gas into a pressure swing adsorption system by using a process of connecting a plurality of columns in series or in parallel, operating in an alternating manner, dividing the raw gas into intermediate gas and concentrated gas, and then performing follow-up treatment; 2) an intermediate gas treatment process: the intermediate gas being non-adsorbed gas, directly discharging or storing the same, or discharging or storing the same post-refinement; 3) a concentrated gas treatment process: the concentrated gas being absorbed gas, and further recovering the same by using an adsorbate recovery and removal process, or removing adsorbate components from the gas.
