PSA (Pressure Swing Adsorption) masu samar da nitrogen tsarin ne da ake amfani da su don samar da iskar nitrogen ta hanyar raba shi da iska. Ana amfani da su da yawa a masana'antu da aikace-aikace daban-daban inda ake buƙatar daidaitaccen wadatar da tsabtar 99-99.999% nitrogen.
Asalin ka'idar aPSA nitrogen janaretaya haɗa da yin amfani da adsorption da zagayawa na desorption. Ga yadda yawanci yake aiki:
Adsorption: Tsarin yana farawa tare da matsa lamba ta hanyar jirgin ruwa mai dauke da wani abu da ake kira sieve kwayoyin halitta. Sive na kwayoyin yana da babban kusanci ga kwayoyin oxygen, yana ba shi damar zaɓar su yaɗa su yayin barin ƙwayoyin nitrogen su wuce.
Rarraba Nitrogen: Yayin da iskar da aka matse ta ratsa ta cikin gadon siffa ta kwayoyin halitta, kwayoyin iskar oxygen suna adsorbed, suna barin iskar iskar nitrogen. Ana tattara iskar nitrogen da adanawa don amfani.
Desorption: Bayan wani lokaci, gadon siffa ta kwayoyin halitta ya zama cikakke da iskar oxygen. A wannan lokaci, an dakatar da tsarin adsorption, kuma an rage matsa lamba a cikin jirgin ruwa. Wannan raguwar matsa lamba yana haifar da ƙwayoyin iskar oxygen da aka ƙaddamar da su don fitar da su daga simintin kwayoyin halitta, yana ba da damar cire shi daga tsarin.
Farfaɗowa: Da zarar an tsabtace iskar oxygen, matsa lamba yana sake ƙaruwa, kuma gadon simintin kwayoyin yana shirye don wani sake zagayowar adsorption. Matsakaicin madaidaicin adsorption da hawan keke na ci gaba da samar da iskar iskar nitrogen mai ci gaba.
PSA nitrogen janaretaan san su da inganci da amincin su. Suna iya samar da nitrogen tare da matakan tsabta masu girma, yawanci jere daga 95% zuwa 99.999%. Matsayin tsarkin da aka samu ya dogara da takamaiman buƙatun aikace-aikacen.
Ana amfani da waɗannan janareta sosai a masana'antu kamar tattara kayan abinci, masana'antar lantarki, magunguna, sarrafa sinadarai, mai da iskar gas, da sauran su. Suna ba da fa'idodi kamar samar da nitrogen a kan yanar gizo, tanadin farashi idan aka kwatanta da hanyoyin isar da nitrogen na gargajiya, da ikon keɓance matakan tsabtace nitrogen bisa takamaiman buƙatu.
