Iyadoo ay yar tahay sahayda oksijiinta caafimaadka ee lagu daweeyo bukaannada Covid-19 ee dalka, Machadka Teknolojiyadda Hindiya ee Bombay (IIT-B) ayaa aasaasay warshad bandhig ah si loogu beddelo matoorada nitrogen ee ku yaal Hindiya oo dhan iyadoo si fiican loo hagaajinayo warshad nitrogen ah oo hore u jirtay oo loo sameeyay matoor oksijiin ah.
Ogsijiin ay warshaddu ka soo saarto shaybaarka IIT-B ayaa la tijaabiyay waxaana la ogaaday inay saafi tahay 93-96% iyadoo cadaadiskeedu yahay 3.5 jawi.
Matoorada Nitrogen-ka, kuwaas oo hawada ka qaada jawiga oo kala sooca oksijiinta iyo nitrogen-ka si ay u soo saaraan nitrogen dareere ah, waxaa laga heli karaa warshado kala duwan oo ay ku jiraan saliidda iyo gaaska, cuntada iyo cabitaanka. Nitrogen-ku waa qalalan yahay dabiiciga waxaana badanaa loo isticmaalaa in lagu nadiifiyo oo lagu nadiifiyo haamaha saliidda iyo gaaska.
Professor Milind Etri, Guddoomiyaha Injineerinka Farsamada, IIT-B, oo ay weheliyaan Tata Consulting Engineers Limited (TCE) ayaa soo bandhigay caddayn muujinaysa fikradda ah in warshad nitrogen ah si degdeg ah loogu beddelo warshad oksijiin.
Warshadda nitrogen waxay isticmaashaa tignoolajiyada nuugista cadaadiska (PSA) si ay u nuugto hawada jawiga, u shaandhayso wasakhda, ka dibna u soo celiso nitrogen-ka. Ogsijiin ayaa dib loogu soo celiyaa jawiga iyadoo ah wax soo saar. Warshadda nitrogen-ku waxay ka kooban tahay afar qaybood: kombaresarada si loo xakameeyo cadaadiska hawada ee la qaato, weel hawo si loo shaandheeyo wasakhda, cutub koronto oo loogu talagalay kala-soocidda, iyo weel kayd ah oo nitrogen-ka kala go'ay la siin doono oo lagu kaydin doono.
Kooxaha Atrey iyo TCE waxay soo jeediyeen in shaandheeyayaasha loo isticmaalo in lagu soo saaro nitrogen-ka cutubka PSA lagu beddelo shaandhooyin soo saari kara oksijiin.
"Warshad nitrogen ah, cadaadiska hawada waa la xakameeyaa ka dibna waa laga nadiifiyaa wasakhda sida uumiga biyaha, saliidda, kaarboon laba ogsaydh iyo hydrocarbons. Intaa ka dib, hawada la nadiifiyey waxay gashaa qolka PSA oo lagu qalabeeyay shaandhooyin kaarboon molecular ah ama shaandhooyin kala sooci kara nitrogen iyo ogsijiin. Waxaan soo jeedinaynaa in shaandhada lagu beddelo shaandho kala sooci karta ogsijiin," ayuu yiri Etry, oo ah khabiir ku takhasusay cryogenics-ka iyo agaasimaha cilmi-baarista iyo horumarinta ee IIT-B.
Kooxdu waxay beddeshay shaandhada kaarboonka molecular-ka ee warshadda nitrogen-ka PSA ee Shaybaarka Qaboojiyaha iyo Shaybaarka Cryogenics iyadoo adeegsanaysa shaandhada molecular-ka ee zeolite. shaandhada molecular-ka ee zeolite waxaa loo isticmaalaa in lagu kala saaro oksijiinta hawada. Iyagoo xakameynaya heerka socodka ee markabka, cilmi-baarayaashu waxay awood u yeesheen inay warshadda nitrogen-ka u beddelaan warshad wax soo saar oksijiin ah. Injineerada Spantech, oo ah soo saaraha warshadda nitrogen iyo oksijiinta ee magaalada, ayaa ka qayb qaatay mashruucan tijaabada ah waxayna ku rakibeen qaybaha dhirta ee loo baahan yahay qaab baloog ah IIT-B si loo qiimeeyo.
Mashruuca tijaabada ah wuxuu higsanayaa in xalal degdeg ah oo fudud loo helo yaraanta oksijiinta ee xarumaha daryeelka caafimaadka ee dalka oo dhan.
Amit Sharma, Agaasimaha Maamulka ee TCE, ayaa yiri: "Mashruucan tijaabada ah wuxuu muujinayaa sida xal wax soo saar oksijiin oo degdeg ah oo cusub oo la adeegsanayo kaabayaasha jira uu uga caawin karo dalka inuu ka gudbo dhibaatada hadda jirta."
"Waxay nagu qaadatay qiyaastii saddex maalmood inaan dib u qalabeyno. Tani waa hab fudud oo si dhakhso ah loo dhammaystiri karo dhowr maalmood gudahood. Warshadaha Nitrogen-ka ee dalka oo dhan waxay isticmaali karaan tiknoolajiyadan si ay dhirtooda ugu beddelaan warshado oksijiin," ayuu yiri Etry.
Daraasadda tijaabada ah, oo lagu dhawaaqay subaxnimadii Khamiista, ayaa soo jiidatay dareenka siyaasiyiin badan. "Waxaan xiiso ka helnay mas'uuliyiin badan oo dowladeed oo aan ahayn oo keliya Maharashtra laakiin guud ahaan dalka oo dhan oo ku saabsan sida tan loo ballaarin karo loona hirgelin karo warshadaha nitrogen ee jira. Waxaan hadda hagaajinaynaa geeddi-socodkeenna si aan uga caawinno dhirta jirta inay qaataan qaabkan." Atrey ayaa raaciyay.
