Shaandhooyinka molecular ee Zeolite waxay door muhiim ah ka ciyaaraan PSA (Cadaadiska Swing Adsorption) geeddi-socodka soo saarista hydrogen, iyo sifooyinkooda xayeysiinta ee xulashada ayaa fure u ah helitaanka nadiifinta hydrogen si hufan. Soo saarista hydrogen ee PSA waa geeddi-socod xayeysiis jireed, waa habka kala-soocidda gaaska oo adeegsata awoodaha xayeysiiska kala duwan ee gaasaska kala duwan ee shaandhada molecular.
Sidee buu u yahay Geedi-socodka Sifaynta Hydrogen?
Sida hydrogen lagu dabaqo qaybo badan oo warshado iyo tamar ah, gaar ahaan unugyada shidaalka iyo warshadaha elektaroonigga ah, waxay leeyihiin shuruudo aad u adag, kaliya hydrogen daahirsanaantiisa ayaa buuxin kara shuruudahan.
Laakiin hydrogen-ka laga soo saaro alaabta ceeriin inta badan waxaa ku jira uumiga biyaha iyo wasakhda sida carbon monoxide, carbon dioxide, methane, nitrogen gas iyo sulfides. Biyahan iyo wasakhdaasi waxay sumayn karaan kicinta, yaraynta waxtarka falcelinta, daxalka qalabka, waxayna keeni karaan khataro badbaado. Sidaa darteed, hababka la xidhiidha nadiifinta hydrogen waxay inta badan diiradda saaraan qalajinta iyo ka saarista wasakhda.
Wax-soosaarka Hydrogen PSA iyo Nadiifinta
Soo saarista hydrogen ee PSA waa mid ka mid ah hababka sifaynta hydrogen ee inta badan loo isticmaalo warshadaha. Waxay si gaar ah ugu habboon tahay nadiifinta hydrogen{1} oo ay ku jiraan gaasyo isku dhafan sida gaaska foornada coke iyo syngas (dib u habaynta gaasta dabiiciga ah, gaasta dhuxusha).
Sifaynta hydrogen ee PSA waxay isticmaashaa awoodaha kala soocida kala soocida ee shaandhada molecular ee cadaadis sare saaran, si ay hydrogen uga soocdo gaaska isku dhafan. Cabbirrada daldaloolada isku midka ah ee shaandhada molecular waxay u oggolaanaysaa inay dabin ku sameeyaan unugyo wasakh ah oo yaryar, oo ay sii daayaan unugyo hydrogen oo waaweyn.
Cabbirkan -Qaabka ka-saarku waxa uu xaqiijiyaa ka saarida wax ku oolka ah ee biyaha iyo wasakhda, soo saarta ultra{1} hydrogen saafi ah oo ku habboon codsiyada muhiimka ah. Iyo shaandhada molecular zeolite waxay noqdeen tiirarka tiirka geeddi-socodkan.
Cadaadis sare, wasakhda ayaa la isku dhejiyaa, halka hydrogen-ka uu dhex maro. Cadaadis hooseeya/vacuum hoostiisa, shaandhada molecular-ku way qurxiyaan (dib u soo nooleeyaan), iyagoo sii daaya wasakhda. Marka la beddelo cadaadiska, hydrogen-nadiifinta sare ayaa si joogto ah loo heli karaa.
Sifooyinka molecular ee Nadiifinta Hydrogen
Daawaynta ka hor ee hawada soo gelisa - ka hor: Kahor inta aan qulqulka gaaska isku dhafan (ka kooban hydrogen, uumiga biyaha, carbon monoxide, carbon dioxide, methane, nitrogen gas, iwm.) ayaa galin nidaamka PSA, nooca 3A ama 4A seeolite shaandho molecular (ama alumina firfircoon) ayaa looga baahan yahay inay marka hore ka saarto biyaha.
Adsorption cadaadis sare: wasakhda (sida carbon monoxide, carbon dioxide, methane, nitrogen gaaska, iwm) waxaa lagu dhejin karaa nooca 5A zeolite shaandho molecular, iyo mararka qaarkood nooca 13X zeolite shaandho molecular ayaa sidoo kale loo isticmaali karaa isku darka.
