Mpweya wa mafakitale uli ndi mpweya wambiri wotayira ndi haidrojeni yosiyanasiyana. Kulekanitsa ndi kuyeretsa haidrojeni ndi chimodzi mwa madera oyambirira kwambiri a ukadaulo wa PSA.
Mfundo ya kulekanitsa mpweya ndi PSA ndikuti mphamvu ya kulowetsedwa kwa mpweya m'zigawo zosiyanasiyana za mpweya imasintha ndi kusintha kwa mphamvu. Zigawo zodetsedwa zomwe zili mu mpweya wolowera zimachotsedwa ndi kulowetsedwa kwa mphamvu yamagetsi, ndipo zodetsedwa zimenezi zimachotsedwa ndi kuchepetsa mphamvu yamagetsi ndi kukwera kwa kutentha. Cholinga chochotsera zodetsedwa ndikuchotsa zinthu zoyera chimakwaniritsidwa kudzera mu kusintha kwa mphamvu yamagetsi ndi kutentha.
Kupanga kwa haidrojeni ya PSA kumagwiritsa ntchito JZ-512H molecular sieve adsorbent kuti ilekanitse haidrojeni wolemera kuti ipange haidrojeni, yomwe imatheka kudzera mu kusintha kwa kuthamanga kwa bedi la adsorption. Chifukwa haidrojeni ndi yovuta kwambiri kunyamula, mpweya wina (womwe ungatchedwe zonyansa) ndi wosavuta kapena wosavuta kunyamula, kotero mpweya wolemera haidrojeni udzapangidwa ukakhala pafupi ndi kuthamanga kwa mpweya wolowetsedwa. Zodetsa zimatulutsidwa panthawi yochotsa (kubwezeretsanso), ndipo kuthamanga kumachepa pang'onopang'ono mpaka kuthamanga kwa desorption.
Nsanja yotsatsira madzi imachita motsatizana njira yotsatsira madzi, kupanikizika, kulinganiza ndi kusungunula kuti ipange hydrogen mosalekeza. Hydrogen wolemera amalowa mu dongosolo pansi pa kupanikizika kwina. Hydrogen wolemera umadutsa mu nsanja yotsatsira madzi yodzazidwa ndi adsorbent yapadera kuchokera pansi mpaka pamwamba. Co / CH4 / N2 imasungidwa pamwamba pa adsorbent ngati gawo lamphamvu la adsorption, ndipo H2 imalowa mu bedi ngati gawo la adsorption. Hydrogen yopangidwa yomwe imasonkhanitsidwa kuchokera pamwamba pa nsanja yotsatsira madzi imatuluka kunja kwa malire. Pamene adsorbent yomwe ili pabedi yadzazidwa ndi CO / CH4 / N2, hydrogen wolemerayo amasinthidwa kukhala nsanja zina za adsorption. Pakutsuka madzi, kupanikizika kwina kwa hydrogen yopangidwa kumatsalirabe mu nsanja yotsatsira madzi. Gawo ili la hydrogen yoyera limagwiritsidwa ntchito kulinganiza ndikutsuka nsanja zina zotsatsira madzi zomwe zangochotsedwa. Izi sizimangogwiritsa ntchito haidrojeni yotsala mu nsanja yoyatsira madzi, komanso zimachepetsa liwiro la kukwera kwa mphamvu mu nsanja yoyatsira madzi, zimachepetsa kutopa mu nsanja yoyatsira madzi, ndipo zimakwaniritsa cholinga cholekanitsa haidrojeni.
Sieve ya molekyulu ya JZ-512H ingagwiritsidwe ntchito kupeza haidrojeni yoyera kwambiri.
