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
Process principle:
After the raw material gas enters the adsorption tower of the PSA device, the adsorption capacity of the adsorbent in the tower for ethane (C2) and hydrocarbon components above C2 varies with the change of pressure. Under pressure, C2 and above hydrocarbon impurities in the raw material are adsorbed, and the unadsorbed gas (purification gas) is exported from the adsorption tower as a product. During decompression, the adsorbed impurities are desorbed and desorbed from the adsorbent, while the adsorbent is regenerated. At least four adsorption bed cycles are used to achieve continuous output of purified gas.
