Mafuta a sulfure otsika kapena nsanja ya desulfurization?Ndani amakonda nyengo

CE Delft, bungwe la kafukufuku ndi upangiri lachi Dutch, posachedwapa latulutsa lipoti laposachedwa kwambiri la zotsatira za dongosolo la EGCS (exhaust gas purification) pa nyengo.Kafukufukuyu anayerekezera zotsatira zosiyana za kugwiritsa ntchito EGCS ndi kugwiritsa ntchito mafuta otsika a sulfure pa chilengedwe.

Lipotili likuti EGCS ili ndi mphamvu zochepa pa chilengedwe kusiyana ndi mafuta ochepa a sulfure a m'nyanja.Lipotilo likusonyeza kuti poyerekeza ndi carbon dioxide yomwe imapangidwa pamene dongosolo la EGC likugwiritsidwa ntchito, mpweya wa carbon dioxide wopangidwa ndi kupanga ndi kukhazikitsa dongosolo la EGC ndi lochepa.Kutulutsa kwa carbon dioxide kumakhudzana makamaka ndi kufunikira kwa mphamvu zamapampu mu dongosolo, zomwe nthawi zambiri zimabweretsa kuwonjezeka kwa 1.5% mpaka 3% ya kuchuluka kwa mpweya woipa.

Mosiyana ndi izi, mpweya woipa wa carbon dioxide umachokera ku ntchito ya mafuta osungunuka umayenera kuganizira njira yoyenga.Malinga ndi mawerengedwe ongoyerekeza, kuchotsa sulfure zili mumafuta kumawonjezera mpweya woipa wa carbon dioxide kuchokera 1% mpaka 25%.Lipotilo limasonyeza kuti n'zosatheka kufika pa chiwerengero chochepa mumtundu uwu mu ntchito yeniyeni.Mofananamo, chiwerengero chapamwamba chidzafikiridwa kokha pamene ubwino wa mafuta ndi wapamwamba kuposa zofunikira zapanyanja.Choncho, zimaganiziridwa kuti mpweya woipa wa carbon dioxide wokhudzana ndi kupanga mafuta otsika a sulfure m'nyanja udzakhala pakati pa zinthu zoopsazi, monga momwe tawonetsera mu chithunzichi.

Jasper Faber, woyang'anira polojekiti ya CE Delft, adati: Kafukufukuyu akupereka chithunzithunzi chokwanira cha momwe nyengo imakhudzira ndondomeko zosiyanasiyana zochepetsera mpweya wa sulfure.Zimasonyeza kuti nthawi zambiri, carbon footprint ntchito desulfurizer ndi wotsika kuposa mafuta otsika sulfure.

Kafukufukuyu akuwonetsanso kuti mpweya wowonjezera kutentha kwa makampani otumiza katundu wakwera ndi 10% pazaka zisanu zapitazi.Zikuyembekezeka kuti mpweya uwonjezeke ndi 50% pofika chaka cha 2050, zomwe zikutanthauza kuti ngati cholinga cha IMO chochepetsa kwambiri mpweya wowonjezera kutentha m'makampaniwa chikwaniritsidwa, mbali zonse zamakampaniwo ziyenera kuwunikiranso.Chimodzi mwazinthu zofunika kwambiri ndikuchepetsa kutulutsa mpweya wa carbon dioxide pamene mukutsatira MARPOL Annex VI.
