Whare Tukatuka Tukatuka Hau Mauri Kounga Nui o Haina - He mokowhiti hau hiku – Rongteng

Whakaahuatanga

Kei te whakamahia te nuinga o te hau o te hau hiku o te taputapu whakaora whanariki, tae atu ki te hau para o te puna wai whanariki me te TEG para hau o te taputapu whakamaroke o te taputapu whakaora whanariki.
Ko te hoahoa me te kaha tukatuka o te reeti ka rite ki te taputapu whakaora whanariki me te taputapu whakamaroke.
Ka taea te wehea te reeti hau hiku o te hau maori kia wha nga waahanga

1. Te mahi whakaheke me te whakauru
Ko te kaupapa o te whakaiti me te tukanga absorption ko te hauwai o te hiku, ka whakahekehia nga waahanga whanariki i roto i te hau hiku ki te H2S, ko te H2S kua hangaia ka tohua ma te tikanga amine, ka mutu ka tangohia te whakahou, te hau ranei ki te whakauru ki te waeine Claus mo te tauhohenga tohanga. He nui te haumi me te utu nui o te mahi mahi, engari e whakamahia ana i roto i nga whenua me nga rohe he nui nga whakaritenga tiaki taiao na te mea ka taea e ia te whakatutuki i te hua whanariki tino nui, penei i te 99.8%.

2 Te hātepe absorption hāora
Ko te tikanga o te hauhautanga he tikanga e whakapouri tuatahi ana i te sulfide i roto i te hau hiku ki te SO2, katahi ka ngohia te SO2 me te otinga (he whakarewa ranei), ka mutu ka hoki mai ano i te ahua o te sulfate, sulfide me te SO2.
He maha nga tikanga e pa ana ki tenei momo, ko te nuinga o enei e whakamahia ana mo te whakakore i te hau rewharewha, te maimoatanga ranei o te hau hiku mai i nga rewa me nga tipu waikawa pungatara, me te tikanga Wellman Lord mo te maimoatanga hau hiku o Claus.

3. Te mahi a Claus te pāmahana iti
Ko te tikanga o te hangarau a Claus te ahua o te tauhohenga a Claus i raro i te toma whanariki, no reira ka kiia hoki ko te tukanga whakaora whanariki. Ko te tauhohenga a Claus he tukanga tauhohenga exothermic kaha. Na reira, ko te iti o te pāmahana he pai ki te neke o te taurite ki te ahunga o te whakatipu whanariki, ka taea te whakapai ake i te whakaora whanariki. E ai ki te hononga i waenga i te tauhohenga a Claus me te waeine, ka taea te wehea te tukanga Claus te pāmahana iti ki te tukanga Claus te pāmahana iti motuhake me te tukanga Claus te pāmahana iti.

4. Wāhanga wai tukanga hāora tika
Wāhanga wai hātepe hāora tika ko te momo o te hangarau tukanga e tika oxidizes H2S ki te whanariki huānga. Ko te maataapono o tenei mahi ko te tango i te H2S i roto i te hau hiku me te otinga whakangao, katahi ka oxidize ki te whakaputa i te whanariki.
