Nitrogen yin gwangwani kwayoyin

A cikin masana'antu filin, nitrogen janareta ne yadu amfani a petrochemical, halitta gas liquefaction, karafa, abinci, Pharmaceutical da kuma Electronics masana'antu. Ana iya amfani da samfuran nitrogen na janareta nitrogen azaman iskar gas, amma kuma azaman albarkatun masana'antu da firiji, wanda shine mahimman kayan aikin jama'a a cikin samar da masana'antu. Tsarin janareta na nitrogen an raba shi zuwa nau'ikan uku: Hanyar rabuwa mai zurfi mai sanyi, hanyar rabuwar membrane da hanyar canza yanayin matsin lamba (PSA).
Hanyar rabuwar iska mai zurfi shine yin amfani da ka'idodin tafasa daban-daban na oxygen da nitrogen a cikin iska, da samar da nitrogen mai ruwa da oxygen ta hanyar ka'idar matsawa, refrigeration da ƙarancin zafin jiki ". Wannan hanya na iya samar da ƙananan zafin jiki na nitrogen da ruwa oxygen, babban sikelin samarwa; Rashin hasara shine babban saka hannun jari, gabaɗaya ana amfani dashi a cikin buƙatun nitrogen da iskar oxygen a masana'antar ƙarfe da masana'antar sinadarai.
Hanyar rabuwa na membrane shine iska a matsayin albarkatun kasa, a ƙarƙashin wasu yanayi na matsa lamba, ta yin amfani da oxygen da nitrogen a cikin membrane tare da nau'o'in haɓaka daban-daban don yin iskar oxygen da nitrogen? Wannan hanya yana da abũbuwan amfãni daga cikin sauki tsarin, babu sauyawa bawul, kananan girma, da dai sauransu, amma saboda membrane abu yafi dogara a kan shigo da, halin yanzu farashin ne tsada da shigar azzakari cikin farji kudi ne low, don haka shi ne yafi amfani da musamman dalilai na musamman. kananan kwarara, kamar mobile nitrogen yin inji.
Hanyar adsorption matsa lamba na kwayoyin halitta (PSA) shine iska a matsayin albarkatun kasa, carbon kwayoyin sieve azaman adsorbent, yin amfani da ka'idar adsorption matsa lamba, yin amfani da simintin kwayoyin carbon don oxygen da nitrogen adsorption da oxygen da hanyar rabuwa ta nitrogen ". Wannan hanyar tana da halaye na kwararar tsari mai sauƙi, babban matakin sarrafa kansa, ƙarancin amfani da makamashi da ƙarancin ƙarancin nitrogen, kuma shine fasahar da aka fi amfani da ita. Kafin iskar ta shiga hasumiyar tallan ɗan adam, dole ne a bushe ruwan da ke cikin iska don rage zaizayar ruwa a kan simintin ƙwayoyin cuta da kuma tsawaita rayuwar simintin ƙwayoyin cuta.
