Nekushomeka kwemidziyo yekurapa yekurapa varwere veCovid-19 munyika, Indian Institute of Technology Bombay (IIT-B) yakagadzira fekitori yekuratidzira kushandura majenareta enitrogen ari muIndia yese nekugadzirisa fekitori yenitrogen iripo yakagadzirwa sejenareta yeoxygen.
Okisijeni yakagadzirwa nechirimwa ichi murabhoritari yeIIT-B yakaedzwa uye yakawanikwa kuti yakachena ne93-96% pakumanikidzwa kwemhepo ye3.5.
Majenareta enitrogen, anotora mhepo kubva mumhepo oparadzanisa okisijeni nenitrogen kuti agadzire nitrogen yemvura, anowanikwa mumaindasitiri akasiyana-siyana anosanganisira mafuta negasi, chikafu nezvinwiwa. Nitrogen yakaoma uye inowanzoshandiswa kuchenesa nekuchenesa matangi emafuta negasi.
Purofesa Milind Etri, Sachigaro weMechanical Engineering, IIT-B, pamwe chete neTata Consulting Engineers Limited (TCE) vakapa humbowo hwepfungwa yekushandura nekukurumidza chirimwa chenitrogen kuita chirimwa cheoxygen.
Chigadzirwa chenitrogen chinoshandisa tekinoroji yepressure swing adsorption (PSA) kusveta mhepo yemuchadenga, kusefa tsvina, uye wozodzosera nitrogen. Okisijeni inodzoserwa mumhepo sechinhu chimwe chete. Chigadzirwa chenitrogen chine zvikamu zvina: compressor yekudzora kumanikidzwa kwemhepo inopinda, mudziyo wemhepo wekusefa tsvina, unit yemagetsi yekuparadzanisa, uye mudziyo webuffer uko nitrogen yakaparadzaniswa ichapihwa nekuchengetwa.
Zvikwata zveAtrey neTCE zvakaronga kutsiva mafirita anoshandiswa kuburitsa nitrogen muPSA unit nemafirita anogona kuburitsa oxygen.
"Muchirimwa chine nitrogen, kumanikidzwa kwemhepo kunodzorwa uye kunocheneswa kubva mutsvina yakaita semvura, mafuta, kabhoni dioxide nemahydrocarbon. Mushure meizvozvo, mweya wakachena unopinda mukamuri rePSA rakashongedzwa nemasefa ecarbon molecular kana mafirita anogona kuparadzanisa nitrogen neokisijeni. Tinokurudzira kutsiva sefa nesefa inogona kuparadzanisa okisijeni," akadaro Etry, nyanzvi mu cryogenics uye director we research and development kuIIT-B.
Chikwata ichi chakatsiva ma "carbon molecular seeves" mu "PSA nitrogen plant" yeInstitute's Refrigeration and Cryogenics Laboratory ne "zeolite molecular seeves". Ma "Zeolite molecular seeves" anoshandiswa kuparadzanisa okisijeni nemhepo. Nekudzora mwero wekuyerera kwemvura muchikepe, vaongorori vakakwanisa kushandura "nitrogen plant" kuita "oxygen production plant". Spantech Engineers, kambani inogadzira "PSA nitrogen and oxygen plant" muguta, vakapinda muchirongwa ichi chekuedza uye vakaisa zvikamu zve "plant" zvinodiwa muchimiro cheblock paIIT-B kuti zviongororwe.
Chirongwa chekuedza ichi chakanangana nekutsvaga mhinduro dziri nyore uye nekukurumidza dzedambudziko rekushomeka kweokisijeni zvakanyanya muzvipatara munyika yese.
Amit Sharma, Mutungamiriri Mukuru weTCE, akati: "Chirongwa ichi chekuedza chinoratidza kuti mhinduro itsva yekugadzira okisijeni yekukurumidzira uchishandisa zvivakwa zviripo inogona kubatsira sei nyika kutsungirira dambudziko riripo."
"Zvakatitorera mazuva matatu kuti tigadzirise patsva. Iri ibasa riri nyore rinogona kupedzwa nekukurumidza mumazuva mashoma. Zvivakwa zvenitrogen munyika yese zvinogona kushandisa tekinoroji iyi kushandura zvirimwa zvavo kuita zvirimwa zveoxygen," akadaro Etry.
Chidzidzo chekuedza, chakaziviswa neChina mangwanani, chakakwezva pfungwa dzevezvematongerwo enyika vakawanda. "Takagamuchira kufarira kubva kuvakuru vehurumende vakawanda kwete muMaharashtra chete asiwo munyika yese pamusoro pekuti izvi zvingawedzerwa sei uye zviitwe sei muzvirimwa zvenitrogen zviripo. Pari zvino tiri kugadzirisa maitiro edu kuti tibatsire zvirimwa zviripo kushandisa muenzaniso uyu." Atrey akawedzera.
