How zeolite molecular sieve works for VPSA Plant?
CHEMXIN 5A oxygen zeolite molecular sieves (ZMS) is special designed for VPSA ( Vacuum pressure Swing Adsorption ) oxygen gas generators, When ZMS used in the VPSA process, nitrogen Molecules having a higher diameter than oxygen Molecule that passes through the pores and are adsorbed. Adsorptive air separation is a cyclic process, in which adsorbent material is alternately.
Three stage in the cyclic process:
Purification: The ambient (inlet) air is filtered before being compressed moderately by a blower system.
Absorption: The pre-treated air passes into a vessel containing activated alumina and zeolites to remove any moisture and CO2 and adsorbs the nitrogen while oxygen passes through the vessel outlet. Before the adsorption capability of the zeolite is exhausted the adsorption process is interrupted.
Desorption: The saturated zeolite is regenerated (i.e. the adsorbed gases released) by means of pressure reduction below adsorption pressure. This is achieved by a dry running vacuum pump. The resulting off gas is vented to atmosphere. In order to continue the cycle, a surge tank was installed to maintain a continuous flow of oxygen supply.
