Iyada oo yaraanta sahayda oksijiinta caafimaadka si loogu daweeyo bukaannada Covid-19 ee dalka, Machadka Teknolojiyadda Hindiya ee Bombay (IIT-B) ayaa dejiyay warshad muujinaya si loogu beddelo koronto-dhaliyeyaasha nitrogen ee ku yaal Hindiya oo dhan iyada oo la hagaajinayo geedka nitrogen ee jira oo loo dejiyay dhaliye oksijiin.
Ogsajiinta ay soo saartay warshadda ku jirta shaybaadhka IIT-B ayaa la tijaabiyay waxaana ay noqotay 93-96% saafi ah cadaadis dhan 3.5 jawi.
Soosaarayaasha Nitrogen-ka, kuwaas oo hawada ka qaada hawada oo kala sooca Ogsajiinta iyo Nitrojiin si ay u soo saaraan nitrogen dareere ah, waxa laga heli karaa warshado kala duwan oo ay ka mid yihiin saliidda iyo gaaska, cuntada iyo cabitaanka. Nitrojiinku dabeecad ahaan waa engegan yahay waxaana caadi ahaan loo isticmaalaa in lagu nadiifiyo oo lagu nadiifiyo taangiyada saliidda iyo gaaska.
Professor Milind Etri, Guddoomiyaha Mechanical Engineering, IIT-B, oo ay weheliso Tata Consulting Engineers Limited (TCE) ayaa soo bandhigay caddayn fikradda ah beddelka degdegga ah ee warshad nitrogen ah oo loo beddelo warshad ogsijiin ah.
Warshada naytrojiinta waxay isticmaashaa tignoolajiyada adsorption swing (PSA) si ay u nuugo hawada atmospheric, u nadiifiso wasakhda, ka dibna u soo kabsato nitrogen-ka. Ogsajiinta ayaa dib ugu soo celisa jawiga sida waxsoosaar ahaan. Warshada nitrogen waxay ka kooban tahay afar qaybood: Compressor si loo xakameeyo cadaadiska hawada qaadashada, weel hawo ah oo lagu sifeeyo wasakhda, unug koronto oo kala soocida, iyo weel kayd ah halkaasoo nitrogen-ka la soocay la keenayo laguna kaydinayo.
Kooxaha Atrey iyo TCE waxay soo jeediyeen in lagu beddelo filtarrada loo isticmaalo in laga soo saaro nitrogen ee unugga PSA shaandhooyin ka soo saari kara ogsijiinta.
"Warshad nitrogen ah, cadaadiska hawada ayaa la xakameynayaa ka dibna laga nadiifiyaa wasakhaha sida uumiga biyaha, saliidda, carbon dioxide iyo hydrocarbons. Taas ka dib, hawada la nadiifiyey waxay gashaa qolka PSA oo ku qalabaysan shaandhada molecular carbon ama filtarrada kala saari kara nitrogen iyo oxygen. Waxaan soo jeedinaynaa in lagu beddelo shaandho shaandho kala sooci karta oksijiinta, "ayuu yiri Etry, khabiir ku takhasusay horumarinta iyo B.
Kooxdu waxay ku beddeshay shaandhooyin molecular kaarboon ah oo ku yaal warshadda nitrogen ee PSA ee Qaboojiyaha iyo Shaybaarka Cryogenics ee Machadka iyagoo isticmaalaya shaandhooyin molecular zeolite ah. Shaleefooyinka molecular ee Zeolite waxaa loo isticmaalaa in lagu kala saaro ogsijiinta hawada. Iyadoo la xakameynayo qulqulka qulqulka markabka, cilmi-baarayaashu waxay awoodeen inay u beddelaan geedka nitrogen ee warshad wax soo saarka oksijiinta. Injineerada Spantech, soo saaraha nitrogen ee PSA ee magaalada iyo warshadda ogsajiinta, ayaa ka qayb qaatay mashruucan tijaabada ah waxayna ku rakibeen qaybaha dhirta loo baahan yahay qaab block ah IIT-B si loo qiimeeyo.
Mashruuca tijaabada ah wuxuu higsanayaa in uu helo xalal deg deg ah oo sahlan ogsajiinta yaraanta ba'an ee xarumaha daryeelka caafimaadka ee dalka oo dhan.
Amit Sharma, Agaasimaha Maamulka ee TCE, ayaa yiri: "Mashruucan tijaabada ah wuxuu muujinayaa sida xal cusub oo soo saarista ogsijiinta degdega ah oo la adeegsanayo kaabayaasha jira ay uga caawin karto dalka inuu qaboojiyo xiisadda hadda jirta."
"Waxay nagu qaadatay ilaa saddex maalmood in aan dib u qalabeyno. Tani waa hab fudud oo si dhakhso ah loo dhamaystiri karo maalmo yar gudahood. Dhirta Nitrogen ee dalka oo dhan waxay isticmaali karaan tignoolajiyadan si ay ugu beddelaan dhirtooda dhirta oksijiinta, "ayuu yiri Etry.
Daraasaddan tijaabada ah oo lagu dhawaaqay subaxnimadii Khamiista, ayaa soo jiidatay indhaha siyaasiyiin badan. "Waxaan ka helnay mas'uuliyiin badan oo dowladeed oo kaliya maahan Maharashtra laakiin dalka oo dhan sida tan loo kordhin karo loona hirgeliyo dhirta nitrogen ee jira. Waxaan hadda hagaajineynaa habkayaga si aan uga caawinno dhirta hadda jirta inay qaataan qaabkan." Ayuu ku daray Atrey.
