Njengoba kuntulakala izinsiza zezokwelapha ze-oxygen zokwelapha iziguli ze-Covid-19 ezweni, i-Indian Institute of Technology Bombay (IIT-B) yasungula isitshalo sokukhombisa ukuguqula abakhiqizi be-nitrogen abatholakala kulo lonke elaseNdiya ngokulungisa isitshalo se-nitrogen esikhona esisungulwe njengomkhiqizi we-oxygen.
I-oksijini ekhiqizwe yisitshalo elabhorethri ye-IIT-B ihlolwe futhi kwatholakala ukuthi ihlanzekile ngo-93-96% ngokucindezela kwemimoya engu-3.5.
Amajeneretha e-nitrogen, athatha umoya emoyeni bese ehlukanisa umoya-mpilo ne-nitrogen ukuze akhiqize i-nitrogen ewuketshezi, angatholakala ezimbonini ezahlukahlukene okuhlanganisa uwoyela negesi, ukudla neziphuzo. I-nitrogen yomile ngokwemvelo futhi ivame ukusetshenziselwa ukuhlanza nokuhlanza amathangi kawoyela negesi.
USolwazi Milind Etri, uSihlalo woBunjiniyela Bemishini, i-IIT-B, kanye ne-Tata Consulting Engineers Limited (TCE) baveze ubufakazi bomqondo wokuguqulwa okusheshayo kwesitshalo se-nitrogen sibe isitshalo se-oxygen.
Isitshalo se-nitrogen sisebenzisa ubuchwepheshe be-pressure swing adsorption (PSA) ukuze simunce umoya womoya, sihlunge ukungcola, bese sibuyisa i-nitrogen. I-oxygen ikhishwa emuva emoyeni njengomkhiqizo ophumayo. Isitshalo se-nitrogen sakhiwe yizingxenye ezine: i-compressor yokulawula umfutho womoya ongenayo, isitsha somoya sokuhlunga ukungcola, iyunithi yamandla yokuhlukanisa, kanye nesitsha se-buffer lapho i-nitrogen ehlukanisiwe izonikezwa futhi igcinwe khona.
Amaqembu e-Atrey kanye ne-TCE aphakamise ukuthi kufakwe izihlungi ezisetshenziselwa ukukhipha i-nitrogen kuyunithi ye-PSA ngezihlungi ezingakhipha umoya-mpilo esikhundleni sazo.
“Esitshalweni se-nitrogen, umfutho womoya uyalawulwa bese uhlanzwa ekungcoleni okufana nomhwamuko wamanzi, uwoyela, i-carbon dioxide nama-hydrocarbon. Ngemva kwalokho, umoya ohlanziwe ungena ekamelweni le-PSA elihlonyiswe ngezisefo zama-molecule e-carbon noma izihlungi ezingahlukanisa i-nitrogen nomoya-mpilo. Siphakamisa ukuthi kufakwe isisefo ngesisefo esingahlukanisa umoya-mpilo esikhundleni saso,” kusho u-Etry, uchwepheshe we-cryogenics kanye nomqondisi wocwaningo nentuthuko kwa-IIT-B.
Ithimba lishintshe izisefo zama-molecule e-carbon esitshalweni se-nitrogen se-PSA se-Refrigeration and Cryogenics Laboratory ye-Institute ngezisefo zama-molecule ze-zeolite. Izisefo zama-molecule ze-Zeolite zisetshenziselwa ukuhlukanisa umoya-mpilo nomoya. Ngokulawula izinga lokugeleza komkhumbi, abacwaningi bakwazi ukuguqula isitshalo se-nitrogen sibe isitshalo sokukhiqiza umoya-mpilo. Onjiniyela be-Spantech, umkhiqizi wesitshalo se-nitrogen ne-oxygen se-PSA edolobheni, bahlanganyele kulo msebenzi wokuhlola futhi bafaka izingxenye zesitshalo ezidingekayo ngesimo sebhulokhi e-IIT-B ukuze zihlolwe.
Iphrojekthi yokuhlola ihlose ukuthola izixazululo ezisheshayo nezilula zokuntuleka komoya-mpilo okukhulu ezikhungweni zezempilo ezweni lonke.
U-Amit Sharma, uMqondisi Ophethe we-TCE, uthe: “Lo msebenzi wokuhlola ukhombisa ukuthi ikhambi elisha lokukhiqiza umoya-mpilo ophuthumayo kusetshenziswa ingqalasizinda ekhona lingasiza kanjani izwe ukubhekana nenkinga yamanje.”
“Kusithathe cishe izinsuku ezintathu ukuhlomisa kabusha. Lena inqubo elula engaqedwa ngokushesha ezinsukwini ezimbalwa. Izitshalo ze-nitrogen ezweni lonke zingasebenzisa lobu buchwepheshe ukuguqula izitshalo zazo zibe izitshalo ze-oxygen,” kusho u-Etry.
Ucwaningo lokuhlola, olwamenyezelwa ngoLwesine ekuseni, ludonsele ukunaka kwezombusazwe eziningi. “Sithole intshisekelo evela ezikhulwini eziningi zikahulumeni hhayi eMaharashtra kuphela kodwa nasezweni lonke mayelana nokuthi lokhu kungakhuliswa kanjani futhi kusetshenziswe kanjani ezitshalweni ze-nitrogen ezikhona. Njengamanje senza inqubo yethu ibe lula ukusiza izitshalo ezikhona ukuthi zisebenzise lo modeli.” Kunezela u-Atrey.
