I-5A ye-sieve ye-pore ubungakanani be-5A, ngaba i-adsorption ingaphantsi kobubanzi bayo nayiphi na i-molecule, isetyenziswa kakhulu ekwahlukaneni kwe-hydrocarbon eyahlukileyo, uxinzelelo lwe-swing adsorption, ukwahlulwa kwe-adsorption kunye namanzi kunye ne-carbon dioxide, esekwe kwiimpawu zokusebenza kwesicelo se-5A thina ekuvelisweni kwe-5A yokusefa yemolekyuli khetha ukubekwa phezulu kwe-adsorption, isantya se-adsorption, ngakumbi efanelekileyo kuxinzelelo lwe-adsorption, inokuziqhelanisa nazo zonke iintlobo zobungakanani beoksijini, i-hydrogen, ikharbon diokside kunye nezinye izixhobo zegesi. iimpahla kumzi mveliso woxinzelelo lwe-swing adsorption (PSA).
