Dhaliyaha Nitrojiinku waa qalab wax-soo-saar nitrogen ah oo loo qaabeeyey lana soo saaray si waafaqsan tignoolajiyada PSA. Dhaliyaha Nitrojiinku wuxuu u isticmaalaa shaandho kaarboon molecular (CMS) sidii adsorbent. Caadi ahaan isticmaal laba munaaradood oo isbarbar socda, kontorool waalka pneumatic-ka soo gelaya si toos ah ay u shaqeyso PLC-ga gelisa, beddelka cadaadiska iyo dib-u-soo-noolaynta, kala-soocidda nitrogen iyo ogsijiinta oo dhammaystiran, si aad u hesho nitrogen-nadiifinta sare ee loo baahan yahay.
Walxaha ceeriin ee shaandho molecular kaarboon waa resin phenolic, marka hore la miiray oo lagu daray walxaha salka, ka dibna daloolada firfircoon. Tignoolajiyada PSA waxay kala saartaa nitrogen iyo ogsijiin ee van der Waals oo ah xooga kaarboonka ee shaandhada molecular, sidaas darteed, bedka dusha sare, inta lebbiska ah ee qaybinta daloolka, iyo tirada badan ee daloolada ama subpores, awoodda xayeysiinta ayaa ka sii weyn.
