Recovery of Carbon Dioxide from Stack Gas by Piston-Driven Ultra-Rapid PSA

摘要: Application of piston-driven ultra-rapid pressure swing adsorption (URPSA) to CO2 recovery from a stack gas was investigated by using model gas. Specific objectives this work are experimentally achieve high capacity CO2, reduction and elucidate the effects moisture contained in on URPSA hydrophilic hydrophobic zeolites. Also, numerical simulations basis simplified mathematical model.CO2 is successfully demonstrated PSA. The accumulated zeolite drastically reduced capacity. However, since accumulation H2O negligibly small case zeolite, should be employed for purpose. production about one order magnitude higher than those conventional PSAs. Still, performance low. It known that decreasing drop adsorbent optimizing sequence control needed improve efficiency. Numerical were successful, developed will useful further investigations.
