Njengoba ukukhathazeka okwandayo emhlabeni wonke ngokuvikelwa kwemvelo, ukunciphisa ukukhishwa kwegesi okuyingozi kuye kwaba yinkinga ebalulekile embonini yokukhiqiza udizili. Ukusetshenziswa kobuchwepheshe bokwelapha igesi yangemuva kubaluleke kakhulu ekunciphiseni ukukhishwa kwegesi eyingozi. Leli phepha lizoxoxa ngokubalulekaigesi yokukhipha ugesiukwelashwa kweamasethi ejeneretha kadizilinokuthi unganciphisa kanjani ngempumelelo ukukhishwa kwegesi okuyingozi.
Okokuqala, sidinga ukuqonda izinto eziyingozi kugesi yokukhipha umoyaamajeneretha kadizili. Amajeneretha kadizilizikhiqiza uhla lwamagesi ayingozi uma zishisa udizili, okuhlanganisa ama-nitrogen oxides (NOx), i-sulfur dioxide (SO2), izinto ezincane (PM) kanye ne-carbon monoxide (CO). Lezi zinto eziyingozi zingalimaza impilo yabantu kanye nemvelo.
Ukuze kuncishiswe ukukhishwa kwegesi okuyingozi,amasethi ejeneretha kadizilikudingeka basebenzise ubuchwepheshe bokwelapha igesi yomsila. Phakathi kobuchwepheshe obuvame kakhulu kukhona ukwehlisa i-catalytic (SCR) kanye nezicupho zama-particulate (DPF). Ubuchwepheshe be-SCR buguqula ama-nitrogen oxide abe yi-nitrogen namanzi angenangozi ngokufaka isisombululo se-urea kugesi yokukhipha umoya. Ubuchwepheshe be-DPF bubamba futhi buhlunge izinhlayiya ukuze zivimbe ukuthi zingangeni emoyeni.
Ngaphezu kobuchwepheshe bokwelapha igesi ekhishwayo, ukusebenza nokugcinwa kwamasethi ejenereyitha kadizili nakho kudlala indima ebalulekile ekunciphiseni ukukhishwa kwegesi okuyingozi. Okokuqala, ukulungiswa njalo nokuhlanzwa kwegesiisethi yejenerethaingaqinisekisa ukusebenza kwayo okuvamile futhi inciphise ukukhishwa kwegesi. Okwesibili, ukukhetha okunengqondo kukaphethiloli kunganciphisa nokukhishwa kwegesi okuyingozi. Ukusetshenziswa kwedizili ene-sulfur ephansi kanye nezithasiselo kunganciphisa ukukhishwa kwegesi ye-sulfur kanye ne-particulate matter. Ngaphezu kwalokho, ukuphathwa komthwalo oqinile kanye namasu okusebenza kunganciphisa nokukhishwa kwegesi okuyingozi.
Ngokuphathelene nokwelashwa kwegesi yokukhipha ugesiamasethi ejeneretha kadizili, ukusekelwa nokuphathwa kukahulumeni kanye nezinhlangano zokuvikela imvelo nakho kudlala indima ebalulekile. Uhulumeni angakha imithethonqubo nezindinganiso ezifanele ukuze kudingekeamasethi ejeneretha kadiziliukusebenzisa ubuchwepheshe bokwelapha igesi ekhishwayo, nokubeka izinhlawulo kumayunithi angahlangabezani nezindinganiso. Izinhlangano zemvelo zinganikeza ukwesekwa kobuchwepheshe kanye nokumela ukukhuthaza intuthuko yeisethi yejenereyitha kadiziliimboni ngendlela enobungani nemvelo.
Ngamafuphi, ukwelashwa kwegesi yokukhipha ugesi kumasethi ejenereyitha kadizili kubalulekile ukunciphisa ukukhishwa kwegesi okuyingozi. Ngokusebenzisa ubuchwepheshe bokwelapha igesi yokukhipha ugesi, ukusebenza kahle nokugcinwa kwamasethi ejenereyitha, kanye nokusekelwa kohulumeni nezinhlangano zezemvelo, singanciphisa ngempumelelo ukukhishwa kwegesi okuyingozi kwamasethi ejenereyitha kadizili kanyevikela imvelokanye nempilo yabantu.
