Nekushomeka kwezvinhu zveokisijeni zvekurapa kurapa varwere veCovid-19 munyika, Indian Institute of Technology Bombay (IIT-B) yakamisa chirimwa chekuratidzira chekushandura majenareta enitrogen anowanikwa mhiri kweIndia nekugadzirisa zvakanaka chirimwa chenitrogen chiripo chakamiswa sejenareta weokisijeni.
Okisijeni inogadzirwa nechirimwa muIIT-B marabhoritari yakaedzwa uye ikaita 93-96% yakachena pakumanikidzwa kwe3.5 atmospheres.
Majenareta eNitrogen, anotora mhepo kubva mumhepo uye anoparadzanisa okisijeni nenitrogen kugadzira mvura yenitrogen, anogona kuwanikwa mumaindasitiri akasiyana siyana anosanganisira oiri negasi, chikafu nechinwiwa. Nitrogen yakaoma muzvisikwa uye inowanzoshandiswa kuchenesa nekuchenesa matangi emafuta negasi.
Muzvinafundo Milind Etri, Sachigaro weMechanical Engineering, IIT-B, pamwe chete naTata Consulting Engineers Limited (TCE) vakapa humbowo hwepfungwa yekukurumidza kushandurwa kwechirimwa chenitrogen kuita chirimwa cheokisijeni.
Iyo nitrogen chirimwa chinoshandisa pressure swing adsorption (PSA) tekinoroji kuyamwa mumhepo yemhepo, kusefa tsvina, uyezve kudzoreredza nitrogen. Oxygen inoburitswa ichidzokera mumhepo sechigadzirwa. Chirimwa chenitrogen chine zvikamu zvina: compressor yekudzora kupinza kwemhepo, mudziyo wemhepo wekusefa kunze tsvina, yuniti yemagetsi yekuparadzanisa, uye mugaba webuffer apo iyo nitrogen yakaparadzaniswa ichapihwa nekuchengetwa.
Zvikwata zveAtrey neTCE zvakaronga kutsiva mafirita anoshandiswa kuburitsa nitrogen muPSA unit nemasefa anogona kuburitsa oxygen.
"Mumushonga wenitrogen, simba remhepo rinodzorwa uye rinocheneswa kubva kune tsvina yakadai semhute yemvura, mafuta, carbon dioxide uye hydrocarbons. Mushure mezvo, mweya wakanatswa unopinda muimba yePSA yakashongedzerwa ne carbon molecular sieves kana ma filters anogona kuparadzanisa nitrogen neokisijeni. Isu tinokurudzira kutsiva sieve nesefa iyo inogona kuparadzanisa kunze kweokisijeni, "akadaro Etry uye mutungamiriri weIITry tsvakurudzo uye mutungamiriri weTryogenic tsvakurudzo.
Chikwata chakatsiva masefa ecarbon molecular muPSA nitrogen chirimwa cheInstitute's Refrigeration uye Cryogenics Laboratory nezeolite molecular sieves. Zeolite molecular sieves anoshandiswa kupatsanura okisijeni kubva kumhepo. Nokudzora chiyero chekuyerera mumudziyo, vatsvakurudzi vakakwanisa kushandura nitrogen chirimwa mukugadzirwa kweokisijeni. Spantech Engineers, yeguta rePSA nitrogen neokisijeni inogadzira chirimwa, vakapinda muchirongwa ichi chekuyedza uye vakaisa zvinodikanwa zvechirimwa mublock fomu kuIIT-B kuti iongororwe.
Iyo pilot purojekiti ine chinangwa chekutsvaga nekukurumidza uye nyore mhinduro dzekushaikwa kweokisijeni kwakanyanya munzvimbo dzehutano munyika yose.
Amit Sharma, Managing Director weTCE, akati: "Chirongwa ichi chekuyedza chinoratidza nzira itsva yekugadzira okisijeni mhinduro uchishandisa zvivakwa zviripo zvinogona kubatsira nyika kutarisana nedambudziko riripo."
"Zvakatitorera mazuva anenge matatu kuti tigadzirire zvakare. Iyi inzira iri nyore inogona kupedzwa nokukurumidza mumazuva mashomanana. Miti yeNitrogen munyika yose inogona kushandisa teknolojia iyi kuti ichinje zvirimwa zvayo mumiti yeokisijeni, "akadaro Etry.
Ongororo iyi, iyo yakaziviswa neChina mangwanani, yakwezva pfungwa dzevezvematongerwo enyika vakawanda. "Takagamuchira kufarira kubva kuvakuru vakuru vehurumende kwete muMaharashtra chete asi nenyika yese pamusoro pekuti izvi zvingakwidziridzwa sei uye zviitwe muzvirimwa zvenitrogen zviripo. Parizvino tiri kugadzirisa maitiro edu kubatsira zvidyarwa zviripo kutora modhi iyi." Atrey akawedzera.
