The adsorption capacity of adsorbents for ethane (C2) and hydrocarbons above C2 varies with pressure after the feed gas enters the adsorption tower of PSA unit. Under pressure, the hydrocarbon impurities above C2 in the feed gas are adsorbed, and the unsorted gas (purified gas) acts from the outlet of the adsorption tower. The adsorbed impurities are desorbed and desorbed from the adsorbent and regenerated at the same time. At least four adsorption beds are circulate to achieve continuous output of purified gas
