Isistimu yokwelapha igesi yokukhipha umoya emkhunjini (ikakhulukazi okuhlanganisa i-denitration kanye ne-desulfurization subsystems) iyisisetshenziswa esibalulekile sokuvikela imvelo yomkhumbi okudingeka ukuthi sifakwe yi-International Maritime Organization (IMO) ingqungquthela ye-MARPOL.Yenza i-desulfurization kanye ne-denitration ukwelashwa okungenabungozi kwegesi ephumayo yenjini ye-diesel yomkhumbi ukuvimbela ukungcoliswa komoya okubangelwa ukukhishwa okungalawuleki kwegesi yokukhipha umkhumbi.
Uma kubhekwa ukwanda kokuqwashisa ngokuvikelwa kwemvelo kanye nokuqashelwa okwandayo kwabanikazi bemikhumbi, isidingo semakethe sezinhlelo zokwelashwa kwegesi ephuma emkhunjini sikhulu.Okulandelayo, sizoxoxa nawe ngezidingo zokucaciswa kanye nezimiso zesistimu:
1. Izidingo zokucaciswa ezifanele
Ngo-2016, i-Tier III yaqala ukusebenza.Ngokwaleli zinga, yonke imikhumbi eyakhiwe ngemva kukaJanuwari 1, 2016, enamandla amakhulu okukhipha injini angu-130 kW nangaphezulu, ehamba eNyakatho Melika nase-US Caribbean Emission Control Area (ECA), inani lokukhishwa kwe-NOx ngeke lidlule ku-3.4 g. /kWh.Izindinganiso ze-IMO Tier I kanye ne-Tier II ziyasebenza emhlabeni jikelele, i-Tier III ikhawulelwe ezindaweni zokulawula ukungcola, futhi izindawo zasolwandle ezingaphandle kwale ndawo zisetshenziswa ngokuvumelana nezindinganiso zeSigaba II.
Ngokomhlangano we-IMO wango-2017, kusukela ngomhlaka-1 Januwari 2020, umkhawulo wesulfure ongu-0.5% womhlaba wonke uzosetshenziswa ngokusemthethweni.
2. Isimiso se-desulfurization system
Ukuze kuhlangatshezwane nezindinganiso ezikhulayo zokukhishwa kwesibabule emkhunjini, abaqhubi bemikhumbi ngokuvamile basebenzisa uwoyela wesibabule esinesibabule esiphansi, amasistimu okwelapha igesi yokukhipha umoya noma amandla ahlanzekile (izinjini zikaphethiloli ezimbili ze-LNG, njll.) nezinye izixazululo.Ukukhethwa kohlelo oluthile ngokuvamile kucatshangelwa umnikazi womkhumbi ngokuhlanganisa nokuhlaziywa komnotho komkhumbi wangempela.
Uhlelo lwe-desulfurization lusebenzisa ubuchwepheshe obumanzi obuyinhlanganisela, futhi izinhlelo ezihlukahlukene ze-EGC (I-Exhaust Gas Cleaning System) zisetshenziswa ezindaweni ezahlukene zamanzi: uhlobo oluvulekile, uhlobo oluvaliwe, uhlobo oluxubile, indlela yamanzi olwandle, indlela ye-magnesium, nendlela ye-sodium ukuhlangabezana nezindleko zokusebenza nokukhipha umoya. .inhlanganisela efanele edingekayo.
