Ujeeddo: Shaleefo molecular Kaarboon waa xayeysiis cusub oo la sameeyay 1970-meeyadii, waa walxo kaarboon ah oo aan dabaylaha ahayn, Kaarboon Molecular Sieves (CMS) oo loo isticmaalo in lagu kala saaro nitrogen-ka kobcinta hawada, iyadoo la adeegsanayo heerkulka qolka cadaadiska hooseeya habka nitrogen, marka loo eego qabow dhaqameed qoto dheer oo sarreeya. Nidaamka nitrogen cadaadisku wuxuu leeyahay kharashyo maalgashi oo yar, Xawaaraha wax soo saarka nitrogen ee sarreeya iyo kharashka nitrogen yar. Sidaa darteed, waa adsorption ee warshadaha ee injineernimada ee doorbiday cadaadiska lulid (PSA) hawada kala soocidda nitrogen adsorbent qani, nitrogen this waxaa si ballaaran loo isticmaalaa in warshadaha kiimikada, warshadaha saliidda iyo gaaska, warshadaha elektarooniga ah, warshadaha cuntada, warshadaha dhuxusha, warshadaha dawooyinka, warshadaha cable, biraha daaweynta kulaylka, gaadiidka iyo kaydinta iyo dhinacyo kale.
