초록

In an adiabatic pressure swing process for separation of feed gas mixtures such as H2 containing CO2 and N2 impurities, at least seven adsorbent beds are employed of which at least two are receiving feed gas during the entire cycle, and with at least three pressure equalization stages.

대표청구항 ▼

In an adiabatic pressure swing process for separation of gas mixtures by selectively adsorbing at least one gas component in each of multiple adsorbent beds by the cycle of introducing feed gas mixture to the bed inlet end at first highest superatmospheric pressure, discharging unadsorbed product effluent from the bed discharge end, releasing initial void space gas from the bed discharge end and introducing the so-released initial gas to the discharge end of another adsorbent bed previously purged of said one component and initially at lower pressure until the two beds are pressure equalized at higher intermediate pressure, releasing gas from the bed inlet end for countercurrent blowdown to lowest pressure, introducing one-component depleted gas from another adsorbent bed to the bed discharge end for desorption of said one component and purging through the bed inlet end, repressurizing the purged bed to said first highest superatmospheric pressure and thereafter repeating the cycle, the improvement comprising at least seven adsorbent beds; simultaneously introducing feed gas mixture to the inlet ends of at least two adsorbent beds in overlapping identical cycles sequentially from the first to the highest numbered bed and thereafter continuously repeating the sequence such that during the initial period of a bed adsorption step the immediately preceding lower numbered bed is also on its adsorption step and during the last period the immediately following higher numbered bed is also on its adsorption step; performing the initial void space gas releasing-pressure equalization in at least three separate phases comprising first pressure equalizing the adsorbent bed having completed its one component adsorption step, with a different previously purged and at least third higher numbered bed initially at lower intermediate pressure so that the two beds are finally at a first equalization pressure; second pressure equalizing the one component-containing adsorbent bed initially at said first equalization pressure with a still different previously purged and at least fourth higher numbered bed initially at still lower intermediate pressure so that the two beds are finally at a second equalization pressure; third pressure equalizing the one component-containing adsorbent bed initially at said second equalization pressure with another previously purged and at least fifth higher numbered bed initially at lowest pressure so that the two beds are finally at a third equalization pressure.
