초록 ▼

A rapid adiabatic pressure swing process with a total cycle time of less than 30 seconds, at least 8 psig feed gas is introduced to a single adsorbent bed of 20-120 mesh particles and bed length not exceeding three times the feed-reverse flow pressure difference and less than 96 inches, a reverse fl

대표청구항 ▼

In a rapid adiabatic pressure swing process for the separation of a multi-component feed gas by selectively adsorbing at least one component in a single adsorption bed of small particles by introducing feed gas to a first end and discharging at least one component depleted gas at the second end with a repetitive two-step cycle sequence at the first end of feed gas introduction and reverse outward flow of at least one component-depleted purging one component desorbate gas and a total cycle time of less than 30 seconds, the improvement comprising; providing said feed gas at pressure of at least 8 psig. at said first end of said adsorbent bed, said feed gas having a separation factor of at least 2 with said adsorbent for feed pressures only less than 30 psig. and said adsorbent bed comprising particles smaller than 20 mesh but larger than 120 mesh being packed in a first to second end length (in inches) not exceeding three times the difference between feed gas and reverse outward flow pressure (in psig.) and less than 96 inches as said adsorbent bed, providing a first end flow suspension step between said feed gas introduction and said reverse outward flow which is less than ten times said feed gas introduction period and also less than one-half a second period of reverse outward flow, and thereafter performing said reverse outward flow for said second period of at least twice the feed gas introduction first period, with the first and second period and gas flows such that the one component enrichment factor is at least 4.
