1. Ijenereyitha yenitrogen yokwahlula umoya weCryogenic
I-cryogenic air yokwahlula i-nitrogen generator yindlela yemveli yokuvelisa i-nitrogen kwaye inembali ephantse ibe ngamashumi eminyaka. Ukusebenzisa umoya njengento ekrwada, emva koxinzelelo kunye nokucocwa, umoya unyibilika ube ngulwelo lomoya ngokutshintshiselana kobushushu.
Umoya olulwelo ubukhulu becala ngumxube weoksijini engamanzi kunye nenitrogen engamanzi. Ngokusebenzisa umahluko kumanqaku abilayo phakathi kweoksijini elulwelo kunye nenitrogen engamanzi (kwi-1atmosphere yoxinzelelo, indawo yokubilisa yangaphambili yi--183° C kwaye le yokugqibela yi -196° C), initrogen ifumaneka ngokuhlukana kwe-liquid air distillation. Izixhobo zokuvelisa i-nitrogen batch cryogenic ziyinkimbinkimbi, zihlala kwindawo enkulu, zineendleko eziphezulu zokwakha, zifuna utyalo-mali olukhulu lwexesha elilodwa kwizixhobo, zineendleko eziphezulu zokusebenza, zivelisa igesi ngokukhawuleza (iiyure ezili-12 ukuya kwii-24), zineemfuno eziphezulu zofakelo kunye nomjikelo omde. Ukuthathela ingqalelo izinto ezahlukeneyo ezifana nezixhobo, ufakelo kunye nolwakhiwo, kwisixhobo esinomthamo we-3,500 Nm3/h okanye ngaphantsi, isikali sotyalo-mali lweeyunithi zePSA ezicaciswe ngokufanayo ngama-20% ukuya kuma-50% ngaphantsi kunaleyo yeeyunithi zokwahlula umoya we-cryogenic. Isixhobo sokuvelisa initrogen ye-cryogenic sifanelekile kwimveliso yenitrogen yemizi-mveliso emikhulu, kodwa ayinoqoqosho kwimveliso yenitrogen ephakathi kunye nencinci.
2. Ijenereyitha ye-nitrogen yesihluzo semolekyuli:
Ukuveliswa kwe-nitrogen ye-PSA yindlela esebenzisa umoya njengezinto eziluhlaza kunye ne-carbon molecular sieves njenge-adsorbents. Yamkela umgaqo we-adsorption yoxinzelelo lwe-swing kwaye isebenzisa i-adsorption ekhethiweyo ye-carbon molecular sieves ye-oxygen kunye ne-nitrogen ukwahlula i-nitrogen kunye ne-oxygen. Le ndlela luhlobo olutsha lweteknoloji yokuvelisa i-nitrogen eyaphuhliswa ngokukhawuleza kwi-1970s.
Xa kuthelekiswa neendlela zemveli zokuvelisa initrogen, ibonisa inkqubo elula, iqondo eliphezulu lokuzisebenzela, ukuveliswa kwegesi ngokukhawuleza (i-15 ukuya kwimizuzu eyi-30), ukusetyenziswa kwamandla aphantsi, ukucoceka kwemveliso ehlengahlengiswayo ngaphakathi koluhlu olubanzi ngokweemfuno zomsebenzisi, ukusebenza ngokufanelekileyo kunye nokugcinwa, iindleko zokusebenza eziphantsi, kunye nokufaneleka kakuhle kwesixhobo.
3. Ijenereyitha yokwahlula umoya we-membrane
Ukusebenzisa umoya njengento ekrwada, phantsi kweemeko ezithile zoxinzelelo, i-oksijini kunye ne-nitrogen kunye nezinye iigesi ezineepropati ezahlukileyo ziyahlukana ngokuthatha inzuzo yamazinga azo ahlukeneyo okungena kwi-membrane.
Xa kuthelekiswa nezinye izixhobo zokuvelisa i-hydrogen, ineenzuzo zesakhiwo esilula, umthamo omncinci, akukho valve yokutshintsha, ukugcinwa okuphantsi, ukuveliswa kwegesi ngokukhawuleza (imizuzu emi-3), kunye nokwandiswa kwamandla okulungeleyo. Ifanelekile ngokukodwa kubasebenzisi abancinci kunye nokucoceka kwe-nitrogen ye-98%. Kwelinye icala, xa ucoceko lwenitrogen lungaphezulu kwama-98%, ixabiso liya kuba ngaphezulu kwe-15% ephezulu kunelo lomatshini wokuvelisa i-nitrogen we-PSA wenkcazelo efanayo.
