Ukuqhathaniswa kwemithombo ye-nitrogen yabakhiqizi be-nitrogen

I-nitrogen ewuketshezi iwumkhiqizo wokuhlukaniswa komoya okubangelwa yi-cryogenic Ukukhiqizwa kwe-nitrogenNgaphansi kwezimo ezijwayelekile, i-1m3 ye-nitrogen ewuketshezi ingafakwa igesi ibe yi-643m3 ye-nitrogen, kodwa izinga lokusetshenziswa langempela ngesikhathi sokusetshenziswa ngokuvamile licishe libe ngu-95%, okungukuthi, i-1m3 ye-nitrogen ewuketshezi ingasebenzisa cishe i-610m3 ye-nitrogen. Njengamanje, intengo yemakethe emaphakathi ye-nitrogen ewuketshezi icishe ibe yi-1,000 yuan/m3, kanti intengo yeyunithi ye-nitrogen ingu-1.67 yuan/m3. Uma usebenzisa i-nitrogen ewuketshezi, abasebenzisi kumele bahlonyiswe ngamathangi okugcina i-nitrogen ewuketshezi, ama-gasifier ahambisana nesilinganiso sokugeleza, kanye nama-valve okulawula ingcindezi ahambisana nengcindezi, okuyizimali zokuqala ezidingekayo.

Ukukhiqizwa kwe-nitrogen yokuhlukaniswa komoya okuhlukaniswa yi-membrane nakho kuyigatsha elisha lokukhiqizwa kwe-nitrogen okungeyona i-cryogenic. Kuyindlela entsha yokukhiqiza i-nitrogen eye yathuthuka ngokushesha kwamanye amazwe ngawo-1980. Isebenzisa umoya njengezinto zokusetshenziswa futhi isebenzisa amazinga ahlukene okugeleza kwe-oxygen ne-nitrogen kuma-membrane e-fiber angenalutho ngaphansi kwengcindezi ethile ukuze ihlukanise i-oxygen ne-nitrogen ukuze ikhiqize i-nitrogen. Uma kuqhathaniswa nezindlela ezimbili zokukhiqiza i-nitrogen ezingenhla, inezici zesakhiwo semishini esilula, usayizi omncane, ama-valve angenawo ama-switching, ukusebenza nokugcinwa okulula, ukukhiqizwa kwegesi okusheshayo (ngaphakathi kwemizuzu emi-3), kanye nokwandiswa kwamandla okulula kakhudlwana.
