LOW ENERGY CYCLIC PSA PROCESS

The invention is drawn to a cyclic pressure swing adsorption (PSA) process to recover an off-gas stream at high pressure with low energy consumption. Each cycle of said process comprises a blowdown phase consisting in lowering the pressure in an adsorbent bed from Phigh to Plow, wherein said blowdow...

More Information
Summary:The invention is drawn to a cyclic pressure swing adsorption (PSA) process to recover an off-gas stream at high pressure with low energy consumption. Each cycle of said process comprises a blowdown phase consisting in lowering the pressure in an adsorbent bed from Phigh to Plow, wherein said blowdown phase is divided into several partial blowdown phases, wherein the gas streams discharged during the partial blowdown phases are introduced into respective discharge tanks.
