Nitrogen kugadzira molecular sieve

Mundima yeindasitiri, jenareta renitrogen rinoshandiswa zvakanyanya mu petrochemical, gasi rechisikigo liquefaction, simbi, chikafu, mishonga uye zvemagetsi indasitiri. Iyo nitrogen zvigadzirwa zve nitrogen jenareta zvinogona kushandiswa sechiridzwa gasi, asiwo semaindasitiri mbishi zvinhu uye refrigerant, inova inodiwa yeruzhinji michina mukugadzirwa kwemaindasitiri. Iyo nitrogen jenareta inonyanya kukamurwa kuita marudzi matatu: yakadzika inotonhora mhepo yekuparadzanisa nzira, membrane yekuparadzanisa nzira uye molecular sieve pressure shanduko adsorption nzira (PSA).
Yakadzika inotonhora mhepo yekuparadzanisa nzira ndeye kushandisa iyo yakasiyana yekubikira poindi yeokisijeni uye nitrogen mumhepo, uye kugadzirwa kwemvura nitrogen uye yemvura okisijeni kuburikidza nemusimboti wekumanikidza, firiji uye yakaderera tembiricha distillation ". Iyi nzira inogona kuburitsa yakaderera tembiricha yemvura nitrogen uye yemvura okisijeni, chiyero chikuru chekugadzira; iyo yakashata ndeyekudyara kukuru, kunowanzo shandiswa muitrojeni neokisijeni kudiwa muindasitiri yemakemikari nesimbi.
Membrane separation method imhepo seyakabikwa, pasi pemamwe mamiriro ekumanikidzika, uchishandisa okisijeni nenitrogen mu membrane ine mwero wakasiyana wepermeability kugadzira oxygen nenitrogen kupatsanurwa?. Iyi nzira ine zvakanakira chimiro chakareruka, hapana switching valve, vhoriyamu diki, nezvimwewo, asi nekuti iyo membrane zvinhu zvinonyanya kuenderana nekunze, mutengo wazvino unodhura uye mwero wekupinda wakaderera, saka inonyanya kushandiswa kune zvakakosha zvekuyerera kudiki, senge mobile nitrogen kugadzira muchina.
Molecular sieve pressure adsorption method (PSA) ndiyo mhepo seyakabikwa, carbon molecular sieve as adsorbent, kushandiswa kwepressure adsorption principle, kushandiswa kwecarbon molecular sieve for oxygen and nitrogen adsorption and oxygen and nitrogen separation method ". Iyi nzira ine hunhu hwekuyerera kwakareruka, dhigirii yakakwira yekushandiswa uye yakakwira nitrogen. mhepo inopinda mushongwe yemunhu, mvura iri mumhepo inofanira kuomeswa kuti ideredze kukukurwa kwemvura pa molecular sieve uye kuwedzera hupenyu hwesevhisi hwema molecular sieve, shongwe yekuomesa inowanzoshandiswa kubvisa mwando mumhepo.
