Dhaliyaha nitrogen-ku waa tignoolajiyada sare u kaca ee gaasta.Shaleefo kaarboon molecular molecular oo tayo sare leh oo la soo dhoofiyo (CMS) ayaa loo isticmaalaa sidii adsorbent, iyo gaasta nitrogen-nadiifinta sare leh waxaa lagu diyaariyaa iyadoo la kala saarayo hawada heerkulka caadiga ah iyada oo la raacayo mabda'a adsorption lulid cadaadis (PSA).
Heerarka faafidda ogsijiinta iyo unugyaraha gaaska nitrogen ee dusha sare ee shaandhada molecular way kala duwan yihiin.Unugyada gaaska ee leh dhexroor yar (O2) waxay leeyihiin xawaare fidin degdeg ah, in badan oo ka mid ah micropores-yada galaya shaandhada molecular kaarboon, iyo heerka faafidda unugyada gaaska dhexroorka weyn (N2).Si tartiib ah, waxaa jira micropores yar oo galaya shaandhada molecular carbon.Farqiga adsorption ee u dhexeeya nitrogen iyo oxygen by shaandho molecular ee kaarboon waxay keentaa tayeynta Ogsajiinta marxaladda adsorption muddo gaaban gudaheed, kobcinta nitrogen ee wajiga gaaska, si ay Ogsajiinta iyo nitrogen u kala soocaan, iyo wajiga gaaska la hodmo. nitrogen waxaa lagu helaa xaalada PSA.
Muddo ka dib, xajinta ogsijiinta ee shaandhada molecular waa mid dheellitiran.Marka loo eego awoodda adsorption ee kala duwan ee shaandhada molecular carbon ee gaaska adsorbed ee cadaadisyo kala duwan, cadaadiska ayaa hoos loo dhigayaa si loo demiyo shaandhada molecular carbon, iyo geeddi-socodku waa dib u soo kabashada.Marka loo eego cadaadiska dib-u-soo-nooleynta ee kala duwan, waxaa loo qaybin karaa dib-u-soo-nooleynta vacuum iyo dib-u-soo-nooleynta cadaadiska hawada.Dib-u-soo-nooleynta jawigu waxay sahlaysa dib-u-soo-nooleynta dhamaystiran ee shaandhada molecular, taasoo sahlaysa in la helo gaasas nadiif ah oo sarreeya.
Matooriyaha nitrogen-ka ee lulaya cadaadiska (oo loo yaqaan PSA nitrogen-generator) waa aalad soo saarta nitrogen oo loo qaabeeyey lana soo saaray iyadoo loo eegayo tignoolajiyada xayeysiinta lulida cadaadiska.Caadi ahaan, labada munaaradood ee adsorption waxay ku xiran yihiin si isbarbar ah, iyo nidaamka xakamaynta tooska ah ayaa si adag u xakameynaya waqtiga iyadoo loo eegayo taxane barnaamij gaar ah, si beddel ah u fuliyaa adsorption cadaadis iyo dib u soo kabashada, dhamaystirto kala soocida nitrogen iyo oksijiinta, waxayna helaysaa gaaska nitrogen-nadiifinta sare.
