I-CE Delft, inhlangano yamaDashi yocwaningo kanye neyokubonisana, isanda kukhipha umbiko wakamuva ngomthelela wesistimu ye-EGCS yasolwandle (exhaust gas purification) esimweni sezulu.Lolu cwaningo luqhathanise imiphumela ehlukene yokusebenzisa i-EGCS nokusebenzisa amafutha asolwandle anesulfure ephansi endaweni ezungezile.
Umbiko uphetha ngokuthi i-EGCS inomthelela omncane emvelweni kunamafutha aphansi e-sulphur olwandle.Umbiko uveza ukuthi uma kuqhathaniswa ne-carbon dioxide ekhiqizwa lapho uhlelo lwe-EGC lusebenza, ukukhishwa kwe-carbon dioxide okukhiqizwa ukukhiqizwa nokufakwa kohlelo lwe-EGC kuncane.Ukukhishwa kwe-Carbon dioxide kuhlobene kakhulu nesidingo samandla samaphampu ohlelweni, okuvame ukuholela ekwenyukeni ngo-1.5% kuya ku-3% wengqikithi yokukhishwa kwe-carbon dioxide.
Ngokuphambene, ukukhishwa kwe-carbon dioxide okuvela ekusetshenzisweni kwezibaseli ezikhishwe yi-desulfurized kudinga ukucabangela inqubo yokucwengwa.Ngokwezibalo zethiyori, ukususa okuqukethwe kwesulfure kuphethiloli kuzonyusa ukukhishwa kwe-carbon dioxide kusuka ku-1% kuya ku-25%.Umbiko ubonisa ukuthi akunakwenzeka ukufinyelela isibalo esiphansi kulolu hlu ekusebenzeni kwangempela.Ngokufanayo, amaphesenti aphezulu azofinyelelwa kuphela uma izinga likaphethiloli lingaphezulu kwezidingo zasolwandle.Ngakho-ke, kufinyelelwa esiphethweni sokuthi ukukhishwa kwe-carbon dioxide okuhlobene nokukhiqizwa kwamandla aphansi e-sulphur olwandle kuzoba phakathi kwalezi zindinganiso ezidlulele, njengoba kuboniswe esithombeni esinamathiselwe.
UJasper Faber, oyimenenja yephrojekthi yakwa-CE Delft, uthe: Lolu cwaningo lunikeza umbono obanzi womthelela wesimo sezulu wezinhlelo ezahlukene zokunciphisa ukukhishwa kwesibabule.Kubonisa ukuthi ezimweni eziningi, i-carbon footprint yokusebenzisa i-desulfurizer iphansi kunaleyo kaphethiloli ophansi wesulfure.
Lolu cwaningo luphinde luveze ukuthi ukukhishwa kwesisi esingcolisa umoya embonini yemikhumbi kukhuphuke ngamaphesenti angaphezu kuka-10 kule minyaka emihlanu edlule.Kulindeleke ukuthi ukukhishwa kwegesi kukhuphuke ngamaphesenti angama-50 ngo-2050, okusho ukuthi uma umgomo we-IMO wokunciphisa kakhulu ukukhishwa kwesisi esingcolisa umoya kule mboni kufanele kufezwe, zonke izici zemboni kufanele zibuyekezwe.Esinye sezinyathelo ezibaluleke kakhulu ukunciphisa ukukhishwa kwe-carbon dioxide ngenkathi kuhambisana ne-Annex VI ye-MARPOL.
