Whakaahuatanga

Ko te whakakorenga hau maori (decarbonization) te paheketanga, he taputapu matua mo te purenga hau maori, te maimoatanga ranei.

Ko te ihirangi o te waro hauhaa i roto i te paerewa kounga hau maori kaua e neke ake i te 3%. Na te hauhā i roto i te wai i muri i te maitai he ha'iriiri tino kaha. Mena he rite te uara pH, he nui ake ano te tauwehenga waikawa o te waro hauhaa, no reira ka nui ake ano te tohu waikura o te waro hauhaa ki runga maitai.

Na reira, mo te tono mo te whakakorenga o te hau o te hau, he mea tika kia kaha te kaha o te wera i roto i te tukanga o te whakakore, na te hau taiao i muri i te whakamakuku whakamahana wera kaore e pai mo te whakakore i te hau. Heoi, ki te kore tatou e whai whakaaro ki nga hua o te whakakorenga hau maaori, engari ka mau ki te tikanga o te wehewehenga iti o te pāmahana, ka arahi tika atu ki te pai o te whakamaarama hau. I tenei wa, ka taea e te whakamahi i te maimoatanga hau o te hau maori te hanga tikanga haukini waipiro.

Tūtohi rere

E ai ki nga ahuatanga o te hangarau MDEA, ka hiahiatia he waahanga whakahou mo te whakakorenga hau. I roto ia ratou, ko te hau maori te nuinga o te uru ki roto ki te kaihoroi mai i raro, ka whakapiri atu ki te otinga MDEA mai i runga ki raro i roto i te kaihoroi, engari ko te nuinga o te otinga waro hauhaa i roto i te hau maori kua whakakorehia. Ko te hau mākū mākū te nuinga wehea e te pourewa absorption me te matao, a ka dehydrated. Ko te MDEA mai i te raro o te pourewa absorption e hiahia ana ki te kaha ki te whakauru ki te maimoatanga matewai, me te waahanga o runga o te pourewa absorption ka uru ki te pourewa. Whai muri i te whakahekenga, ka whakatauhia te waro hauhaa ka whakamahana ma te mamaoa i waenganui o te pourewa whakaora. Ma tenei anake ka taea te pupuri i te pāmahana otinga. I muri i te whakamatao o te otinga MDEA mai i raro o te pourewa, ka uru te otinga ki te tihi o te whakaurunga, kia oti ai te katoa o te tohanga o te otinga. I tua atu, kia pai ai te whakarite ka taea te hangarua me te horoi ano i te otinga, me 15% o te otinga mo te tango otinga. Kia mau tonu ai te tukanga whakakore warowaiha o te hau maori, ka whakahouhia te punaha ma te otinga.

Nga waahanga mahi

Ko te kaha o te whakakorenga ma te tikanga MDEA he 99%.
Hei tango i te hauhau waro (CO2) mai i te hau whangai, ko te wairewa wai me te amine waipiro hei tauhohe te whakarewa ki te CO2 i roto i te hau whangai. He iti te mate hau me te nui o te whakapau kaha. Ka taea hoki te whakamahi i te tikanga amine waipiro hei tango i te H2S mai i te hau whangai.
