Te tukanga whakaputa hauwai hau maori tuku iho

E whā ngā wāhanga o te tukanga whakaputa hauwai mai i te hau maori: te maimoatanga hau whāngai, te hurihanga mamaoa, te hurihanga CO2 me te purenga hauwai.

(1) Ko te wāhanga maimoatanga hau whāngai te nuinga o te wā e whakamahia ana mō te tango i te whanariki o te hau māori, ā, ko ngā tango i te whanariki MnO me te ZnO e whakamahia ana hei tango i te H2S me te SO2. He nui te kaha tukatuka o te hau whāngai, nō reira ka tīpakohia he pūwero nui i te wā e pēhi ana i te hau whāngai.

(2) Wāhanga hurihanga mamaoa. Ka whakamahia te mamaoa wai hei waikura hei huri i ngā warowaihā i raro i te mahi a te whakakorikori nikara kia whiwhi ai i te hau hurihanga mō te hanga hauwai. He āhuatanga motuhake te momo me te hanganga o te kaiwhakahou, ā, he rerekē anō hoki te hanganga, te aratau utu wera me te aratau whakatika o ngā kaikohi hau o runga me raro. Ahakoa he rerekē te whakatakotoranga o ngā whakawhiti wera i roto i te wāhanga whakawhiti wera, ka whakamahia ngā tawhā mahi tukanga o te hurihanga pāmahana-tiketike me te ōwehenga waro wai iti i roto i te wāhanga hurihanga mamaoa, he mea whai hua ki te whakapai ake i te hohonutanga hurihanga me te penapena i te whakamahinga rauemi mata.

(3) Wāhanga hurihanga CO. Kei roto i te hau whāngai i tukuna mai i te kaiwhakahou he nui o te Co. Ko te mahi o te hurihanga he mea kia tauhohe te co ki te mamaoa hei whakaputa i te CO2 me te H2 i te aroaro o te whakakorikori. E ai ki te pāmahana hurihanga, ka taea te wehewehe i te tukanga hurihanga ki te hurihanga pāmahana teitei (350 ~ 400 ℃) me te hurihanga pāmahana waenga (iti iho i te 300 ~ 350 ℃). I ngā tau tata nei, nā te aro nui ki te tiaki rauemi, kua whakamahia te tautuhinga tukanga hurihanga e rua-wāhanga o te hurihanga pāmahana teitei CO me te hurihanga pāmahana iti i roto i te tautuhinga tukanga o te wāhanga hurihanga, kia iti ake ai te kai o ngā rauemi mata.

(4) Wāhanga purenga hauwai. I roto i te tukanga, kua whakamahia e ia kamupene whakaputa hauwai te pūnaha purenga me te wehenga pēhanga piu (PSA) me te iti o te whakapaunga pūngao hei whakakapi i te pūnaha tango waro me te purenga me te tukanga matū methane me te nui o te whakapaunga pūngao, kia tutuki ai te whāinga o te penapena pūngao me te whakangawari i te tukanga, ā, ka taea te tiki hauwai me te parakore tae atu ki te 99.9% i te putanga o te wāhanga.
