Zomera za nayitrogeni zoyera zakhala zofunikira kwambiri m'mafakitale angapo monga mankhwala, zamagetsi, ndi ntchito zamankhwala. Nayitrojeni ndi gawo lofunikira kwambiri pafupifupi m'mafakitale onsewa, ndipo ukhondo wake ndi mtundu wake zimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti zinthu zomaliza zimakhala zabwino. Chifukwa chake, kupanga nayitrogeni wapamwamba kwambiri ndikofunikira kwambiri.
Pressure swing adsorption (PSA) ndiukadaulo womwe ungagwiritsidwe ntchito kuyeretsa nayitrogeni pochotsa mpweya ndi zonyansa zina. PSA imachokera pa mfundo ya kutsatsa kwa gasi pa chinthu cholimba cha adsorbent. The adsorbent amasankhidwa mosankha kutengera luso lake adsorb mpweya mamolekyu chidwi, pamene kulola mpweya wina kudutsa.
Mu chomera choyera kwambiri cha nayitrogeni, ukadaulo wa PSA ungagwiritsidwe ntchito kupanga nayitrogeni kapena mpweya powongolera kutengeka ndi kuwonongeka kwa mamolekyu a gasi. Njirayi imaphatikizapo kukanikiza mpweya kuti ukhale wolimba kwambiri ndikudutsa pabedi la adsorbent. Zinthu za adsorbent zidzakometsa mpweya ndi zonyansa zina, pamene nayitrogeni imadutsa pabedi ndipo imasonkhanitsidwa mu thanki yosungirako.
Zinthu za adsorbent zimatha kubwezeretsedwanso mwa kumasula mphamvu, zomwe zimapangitsa kuti mamolekyu a gasi awonongeke kuchokera kuzinthuzo. The gasi desorbed ndiye kudutsa dongosolo, ndipo adsorbent ndi wokonzeka adsorb mkombero wina wa mamolekyu gasi.
Ubwino wina waukulu wogwiritsa ntchito ukadaulo wa PSA muzomera za nayitrogeni zoyera kwambiri ndizotsika mtengo. Ukadaulo wa PSA ndiwothandiza kwambiri ndipo sufuna zida zovuta kapena anthu apadera kuti agwire ntchito. Kuonjezera apo, ili ndi ndalama zochepa zogwirira ntchito, chifukwa sichifuna gwero lililonse lakunja la mphamvu kupatula mpweya woponderezedwa.
Ubwino wina ndi wosinthasintha. Tekinoloje ya PSA imatha kupanga nayitrogeni ndi mpweya, kutengera zomwe zasankhidwa. Mpweya wokhala ndi okosijeni ukhoza kugwiritsidwa ntchito m'mafakitale angapo monga ntchito zamankhwala ndi kuwotcherera, momwe mpweya wambiri umafunikira.
Komabe, kupanga nayitrogeni kapena mpweya wabwino kwambiri kudzera muukadaulo wa PSA kumafuna kusankha mosamala zinthu za adsorbent. Zinthu zopangira ma adsorbent ziyenera kukhala ndi kusankha kwakukulu kwa ma molekyulu a gasi osangalatsa ndipo ziyenera kukhala zoyenererana ndi momwe zimagwirira ntchito pazomera za nayitrogeni. Kuphatikiza apo, kukula ndi mawonekedwe a zinthu za adsorbent ziyenera kukonzedwa bwino kuti muchepetse kutsika ndikuwonetsetsa kutsatsa koyenera.
Pomaliza, ukadaulo wa PSA ndi njira yabwino kwambiri komanso yotsika mtengo yopangira nayitrogeni yoyera kwambiri kapena mpweya muzomera za nayitrogeni zoyera kwambiri. Imakhala ndi maubwino angapo, kuphatikiza kusinthasintha komanso kutsika mtengo kwantchito. Komabe, kusankha mosamala zinthu za adsorbent ndikofunikira kuti zitsimikizire chiyero chomwe mukufuna komanso mtundu wa nayitrogeni kapena mpweya wopangidwa. Ndi maubwino ake ambiri, ukadaulo wa PSA ndi njira yowoneka bwino yamafakitale omwe amafunikira mtundu wapamwamba kwambiri, wodalirika wa nayitrogeni.
