Summary

PRESSURE SWING ADSORPTION (PSA) AIR PURIFICATION/VAPOUR RECOVERY WAS STUDIED BY EXPERIMENTS AND MODEL SIMULATIONS USING DIMETHYL METHYLPHOSPHONATE (DMMP) VAPOUR AND ACTIVATED CARBON. COMPLETE CLEANUP OF THE PRODUCT EFFLUENT RESULTED WHEN STARTING FROM A SATURATED BED EVEN FOR THE VERY STRONGLY ADSORBED VAPOUR, DMMP. AT THE SAME TIME, A CONCENTRATED DMMP VAPOUR WAS PRODUCED AT THE EXHAUST EFFLUENT. THEREFORE, PSA CANNOT ONLY BE USED TO PURIFY AIR, IT CAN ALSO CONCENTRATE THE VAPOUR FOR MORE EFFICIENT RECOVERY OR ABATEMENT. ALSO, 2 CYCLIC STEADY STATES WERE DEMONSTRATED BOTH EXPERIMENTALLY AND THEORETICALLY. WHEN STARTING FROM A CLEAN BED, THE CONCENTRATION WAVE PENETRATED THE BED VERY SLOWLY WHILE A CYCLIC STEADY STATE WAS BEING APPROACHED AND MUCH OF THE BED REMAINED UNUSED.
