Igesi yezimboni iqukethe inqwaba yamagesi alahlwayo ane-hydrogen ehlukahlukene. Ukuhlukaniswa nokuhlanzwa kwe-hydrogen nakho kungomunye wemikhakha yokuqala yezimboni yobuchwepheshe be-PSA.
Umgomo wokuhlukaniswa kwe-PSA kwengxube yegesi ukuthi amandla e-adsorption e-adsorbent ezingxenyeni ezahlukene zegesi ashintsha ngokushintsha kwengcindezi. Izingxenye zokungcola kugesi elingena ngaphakathi zisuswa i-high-pressure adsorption, futhi lokhu kungcola kuhlanjululwa ngokunciphisa ingcindezi nokukhuphuka kwezinga lokushisa. Inhloso yokukhipha ukungcola kanye nokukhipha izingxenye ezihlanzekile kufinyelelwa ngokucindezela noshintsho lokushisa.
Ukukhiqizwa kwe-hydrogen ye-PSA kusebenzisa i-JZ-512H ye-molecular sieve adsorbent ukuze ihlukanise i-hydrogen ecebile ukuze ikhiqize i-hydrogen, eqedwa ngokushintsha kwengcindezi yombhede we-adsorption. Ngenxa yokuthi i-hydrogen inzima kakhulu ukukhangiswa, amanye amagesi (angase abizwe ngokuthi ukungcola) kulula noma kulula ukukhangiswa, ngakho-ke igesi ecebile nge-hydrogen izokhiqizwa uma isiseduze nomfutho we-inlet wegesi ehlanziwe. Ukungcola kukhishwa ngesikhathi sokuncibilika (ukuvuselelwa), futhi umfutho wehla kancane kancane ube yi-desorption pressure.
Umbhoshongo we-adsorption wenza inqubo ye-adsorption, ingcindezi. Equalization kanye desorption ukufeza ukukhiqizwa okuqhubekayo hydrogen. I-hydrogen ecebile ingena ohlelweni ngaphansi kwengcindezi ethile. I-hydrogen ecebile idlula embhoshongweni we-adsorption ogcwele i-adsorbent ekhethekile ukusuka phansi kuye phezulu. I-Co / CH4 / N2 igcinwa ebusweni be-adsorbent njengengxenye ye-adsorption enamandla, futhi i-H2 ingena embhedeni njengengxenye ye-adsorption. I-hydrogen yomkhiqizo eqoqwe kusukela phezulu kombhoshongo we-adsorption ikhishwa ngaphandle komngcele. Lapho i-adsorbent embhedeni igcwele i-CO / CH4 / N2, i-hydrogen ecebile ishintshelwa kweminye imibhoshongo ye-adsorption. Enqubweni ye-adsorption desorption, ingcindezi ethile yomkhiqizo we-hydrogen isasele kumbhoshongo we-adsorbed. Le ngxenye ye-hydrogen ehlanzekile isetshenziselwa ukulinganisa kanye nokushaya enye imibhoshongo elinganisa ingcindezi esanda kususwa. Lokhu akwenzi kuphela ukusetshenziswa kwe-hydrogen esele embhoshongweni we-adsorption, kodwa futhi kunciphisa isivinini sokuphakama kwengcindezi embhoshongweni we-adsorption, kunciphisa izinga lokukhathala embhoshongweni we-adsorption, futhi kufeza ngempumelelo inhloso yokuhlukaniswa kwe-hydrogen.
Isisefo se-molecular JZ-512H singasetshenziswa ukuthola i-hydrogen ehlanzekile.
