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 rabuwa mai zurfi mai zurfi shine yin amfani da ka'idodin tafasa daban-daban na oxygen da nitrogen a cikin iska, da kuma samar da ruwa nitrogen da oxygen ta hanyar ka'idar matsawa, refrigeration da ƙananan zafin jiki distillation.
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 hanyar tana da fa'idodi na tsari mai sauƙi, babu bawul ɗin canzawa, ƙaramin ƙara, da sauransu, amma saboda kayan aikin membrane galibi ya dogara da shigo da kaya, farashin yanzu yana da tsada kuma ƙimar shigar cikin ƙasa ba ta da yawa, don haka ana amfani da shi galibi don dalilai na musamman na ƙananan kwarara, kamar injin yin nitrogen ta hannu.
Molecular sieve matsa lamba Hanyar (PSA) ne iska a matsayin albarkatun kasa, carbon kwayoyin sieve kamar yadda adsorbent, da yin amfani da matsa lamba adsorption manufa, da yin amfani da carbon kwayoyin sieve for oxygen da nitrogen adsorption da oxygen da nitrogen rabuwa Hanyar ". Wannan hanya yana da halaye na sauki tsari kwarara, babban mataki na aiki da kai, low makamashi amfani da high nitrogen iska mafi yawan amfani da fasahar, kuma shi ne yadu shigar da fasahar, kuma shi ne yadu shigar da mutum iska. Ruwa a cikin iska dole ne a bushe don rage yazawar ruwa a kan kwayoyin sive da kuma tsawanta da sabis na kwayoyin sieve A cikin al'ada PSA nitrogen tsarin, da bushewa hasumiya da aka saba amfani da su cire danshi a cikin iska Lokacin da bushewa hasumiya da aka hura baya da bushe iska don gane da bushewa na bushewa hasumiya.
