Abashakashatsi bo muri kaminuza ya Chung-Ang muri Koreya y’Epfo bariko bariga ingene umuyagankuba ufatwa n’ingene uwukoreshwa bakoresheje imyanda canke ubutunzi bw’ibidukikije nk’ibifungurwa. Ivyo bituma ubuhinga bushobora gutera imbere mu vy’ubutunzi.
Muri iyo nyigisho nshasha, umugwi uyobowe na Porofeseri Sungho Yoon be na Porofeseri wungirije Chul-Jin Lee barasuzumye ukuntu umwuka w’ikirere w’inganda n’umuyagankuba w’amabuye yitwa dolomite ukoreshwa mu guhingura ibintu bibiri bishobora gucuruzwa: calcium formate na magnésium oxide.
Ico cigwa citwa “Guhindura bimwe bikomeye ivyuma vy’i Dolomite bifise agaciro hakoreshejwe umwuka w’ikirere,” carasohowe mu kinyamakuru kimwe (Journal of Chemical Engineering).
Ihinduka ry’ikirere ni ikibazo gikomeye gikeneye kwitwararikwa imbere y’ibindi vyose. Ivyo bituma ibihugu vyo kw’isi yose bitegura amategeko yo kugabanya ingaruka zavyo.
Nk’akarorero, Ubumwe bw’Uburaya burasaba ko habaho ingingo ngenderwako zitomoye zo gushika ku kutagira aho bahengamiye mu bijanye n’imihindagurikire y’ikirere mu 2050. Amasezerano y’Uburayi yerekeye ivyatsi bitotahaye na yo nyene arashimika ku kamaro ko kugabanya imyuka itera ibidukikije.
Ivyo vyatumye abahinga bariko bararondera ubuhinga bwo gufata no gukoresha umwuka w’ikirere nk’uburyo bwiza bwo kwagura ububiko n’ugutunganya umwuka w’ikirere ku giciro gitoyi.
Ariko rero, ubushakashatsi bwo kw’isi yose ku bijanye no gufata no gukoresha umuyagankuba buragarukira ku bihimba nka 20 bihindura.
Kubera ubudasa bw’ibidukikije biva mu CO2, kugira ibintu vyinshi bihurikiye hamwe ni ikintu gihambaye cane.
Ivyo vyerekana akamaro ko kwiga bimwe bigera kure ingene umwuka w’ikirere ufise uburemere buke uhinduka.
Muri iyo nyigisho nshasha, abo bahinga bakoresheje ikintu gitera umuriro (Ru/bpyTN-30-CTF) kugira ngo bongereko ivyuma vy’amazi ku mwuka w’ikirere. Ico vyavuyemwo ni ibintu bibiri vy’agaciro: calcium formate n’oxyde de magnésium.
Calcium formate ikoreshwa nk’ivyo kwongera muri simenti, mu gukuraho urubura, no mu vyo kwongera ku vyo kurya vy’ibikoko, hamwe n’ibindi bikoresho nk’ugukora urukoba.
Ivyo bikoresho vy’iryo tsinda ntibishoboka gusa, ariko kandi biranyaruka cane, bikaba bikora ico kintu mu minota itanu gusa mu bushuhe bwo mu cumba.
Mu bindi, abo bashakashatsi bagereranya ko iyo nzira yoshobora kugabanya ubushuhe bwo kw’isi yose ku rugero rwa 20% ugereranyije n’uburyo bwa kera bwo guhingura calcium formate.
“Hariho ugushimishwa gukomeye kwo gukoresha umwuka w’ikirere kugira ngo umuntu akore ibintu vy’agaciro bishobora gufasha kugabanya ingaruka z’imihindagurikire y’ikirere mu gihe nyene bizana inyungu mu vy’ubutunzi.
Porofeseri Yoon yavuze ati: “Mu gufatanya ibikorwa vy’uguhindura umuyaga w’ikirere n’ivy’uguhinduranya ivyuma, harateguwe uburyo bwo gusukura icarimwe ivyuma vy’umuyagankuba maze bikazana formate y’agaciro.”
Abashakashatsi barasuzumye nimba uburyo bakoresheje bushobora gusubirira uburyo bwo guhingura ibintu buriho ubu. Kugira ngo ivyo babikore, barize ingaruka mbi ku bidukikije no ku butunzi bw’uburyo bwo guhindura CO2 mu buryo buramba.
Porofeseri Yin yasiguye ati: “Twisunze ivyo twabonye, ​​turashobora kuvuga yuko uburyo bwacu ari uburyo bwo guhindura umwuka w’ikirere bushobora gusubirira uburyo bwa kera kandi bugafasha kugabanya umwuka w’ikirere uva mu nganda.”
Naho ivyizigiro vyo guhindura umwuka w’ikirere mu bintu biramvye ari vyiza, ivyo bikorwa ntivyama vyoroshe gutera imbere.
Ivyuma vyinshi vya CCU ntibirashirwa mu bucuruzi kubera ko ubushobozi bwavyo bwo gucuruza mu vy’ubutunzi buri hasi ugereranije n’uburyo bwa kera bwo gucuruza.
Dr Lee yasozereye ati: "Turakeneye gufatanya uburyo bwa CCU n'ugusubira gukoresha imyanda kugira ngo bibe vyiza ku bidukikije no ku bukungu. Ivyo vyoshobora gufasha gushika ku ntego zo kutagira ivyuka bihumanya ikirere muri kazoza."
Innovation News Network irabazanira amakuru mashasha y’ubushakashatsi n’ubuhinga bushasha mu vy’ubuhinga, ibidukikije, inguvu, ibikoresho bihambaye, ubuhinga n’ibinyabiziga bikoresha umuyagankuba.
Ivyiyumviro: Uru rubuga ni urubuga rwigenga kandi ntaco rushinzwe ku birimwo ku mbuga zo hanze. Turabinginze mumenye ko amatelefone yoshobora gufatwa amajwi kugira ngo umuntu amenyerezwe kandi akurikirane. © Ishirahamwe ry’Uburayi ryose Ltd.
