Ka taea te tukatuka i te hau hiku mai i te umanga purenga hau māori mā te tukanga mimiti whakaiti. Ko te kaupapa o te tukanga mimiti me te whakaiti ko te whakahāngai i te hau hiku ki te hauwai, te whakaiti i ngā wāhanga whanariki i roto i te hau hiku ki te H2S, te mimiti i te H2S i hangaia mā te tikanga amine, ā, i te mutunga ka hanga hou, ka tango rānei i te hau, kātahi ka whakauru ki te wae Claus mō te tauhohenga tohanga. He nui te haumitanga me te utu whakahaere o te tukanga whakahāngai hauwai. Heoi, ka taea e ia te whakatutuki i te hua whanariki tino teitei, pērā i te neke atu i te 99.8%, e whakamahia whānuitia ana i roto i ngā whenua me ngā rohe he nui ngā whakaritenga tiaki taiao.
Ko te tikanga mimiti whakaiti e whakauru ana i ēnei tukanga matua: Te tukatuka Scot, te tukatuka HCR, te tukatuka resulf, te tukatuka bsrp me te tukanga RAR.
Ko te tukanga Scot, e kiia nei ko Scot, e pā ana ki te hangarau maimoatanga hau hiku o te tipu whanariki Claus o Dutch Shell. I te nuinga o te wā, ko te tukanga Claus tuku iho (e rua ngā wāhanga, e toru rānei ngā wāhanga) e whakamahia ana mō te whakaora whanariki. Ko te tere whakaora whanariki o tēnei tukanga he tata ki te 95% ~ 97%. I roto i te hapori o ēnei rā, he teitei ake ngā whakaritenga mō te tiaki taiao, ā, he iti iho te tukunga e whakaaetia ana. Mena he nui te kaha o te wae whakaora whanariki, he tino teitei te tere whakaora (99% neke atu rānei). I tēnei take, me whakaaro ki te pūnaha maimoatanga hau hiku super Claus, Scot rānei. Heoi, ki te hiahiatia kia eke te tere whakaora ki runga ake i te 99.5%, ka taea anake te whakamahi i te scot.
Ko te tukanga HCR, te hangarau tukanga HCR i whakawhanakehia e te kamupene nigi Itari, he momo tukanga mimiti whakaiti hauwai. Ko te āhuatanga matua o tēnei tukanga ko te whakamahi i te whakaroa o te tahunga me te wera o te pukahukahu o te hau tukatuka o te oumu hanga whanariki hei whakamahana i te hau hiku, nō reira kāore he hiahia mō te whakamahana tāpiri, kia taea ai te hangarua i te wera para me te whakaiti nui i te utu. Heoi anō, kāore tēnei tukanga e hiahia ki te hauwai tāpiri. Ko te H2 i wetekina e te oumu tahu pāmahana teitei wāhanga Claus he nui hei whakaiti i te toenga o te whanariki ki te H2S.
Te tukatuka resulf i whakawhanakehia e te kamupene TPA, e toru ngā momo o te tukanga resulf: te tukanga resulf, te tukanga resulf-10 me te tukanga resulf mm. Pērā i te tukanga Scot, ka whakamahanahia te hau hiku o te waeine Claus i te tuatahi, kātahi ka konatunatua ki te hau whakaiti i konatunatua ki te H2 hei whakaiti i te hau wāhanga kei roto te whanariki i roto i te tauhohenga ki te H2S. Ka taea te whakamahi i tēnei tukanga hei whakapai ake i te tere whakaora whanariki o te waeine Claus o nāianei.
I whakawhanakehia ngātahitia te tukanga Bsrp e UOP me Parsons. Ko te nuinga o te wā, ka whakamahia te tukanga Bsrp mō te tukatuka hau hiku o te waeine Claus. Kua whānuitia te whakamahinga o tēnei tukanga puta noa i te ao.
Ka taea e te reiti whakaora whanariki katoa o te wae Claus / bsrp te eke ki te neke atu i te 99.8%. Ka whakamahia e te Bsrp te tikanga anthrone hei mimiti i te H2S. He iti te ihirangi H2S i roto i te hau hiku kua tukuna, engari he maha ngā raruraru whakahaere.
Kua whakawhanakehia e te hangarau Rar KTI tētahi tukanga maimoatanga hau hiku e kiia nei ko te rar (te whakaiti, te mimiti me te hangarua). Ko te tukanga e hangai ana ki ngā amine whiriwhiri whakaiti: e mōhiotia whānuitia ana te kaupapa o te tukanga i roto i te umanga, he tata rite ki ngā tukanga rite e whakamahia ana i roto i ētahi atu tono rite. He pono, he whai hua hoki te mahi a te tukanga Rar, ā, ka taea e tōna tere whakaora whanariki te eke ki te 99.9%. Koinei te tukanga whakaora whanariki tino whai hua i roto i te hangarau o nāianei.
