Whakaahuatanga
Ko te paheke hau hiku hau māori e whakamahia ana mō te whakahaere i te hau hiku o te taputapu whakaora whanariki, me te hau para o te puna whanariki wai me te hau para TEG o te taputapu maroke o te taputapu whakaora whanariki.
He rite te hoahoa me te kaha tukatuka o te reti ki te taputapu whakaora whanariki me te taputapu maroke.
Ka taea te wehewehe i te paheke maimoatanga hau hiku hau maori kia whā ngā wāhanga.
1. Te tukanga whakaiti me te mimiti
Ko te kaupapa o te tukanga whakaiti me te mimiti ko te whakahauwai i te hau hiku, ka whakaitihia ngā wāhanga kei roto te whanariki i roto i te hau hiku ki te H2S, ka mimitia te H2S i hangaia mā te tikanga amine, ā, i te mutunga ka tangohia te hau hou, te hau rānei hei whakauru ki te wae Claus mō te tauhohenga tohanga. He nui te haumitanga me te utu whakahaere o te tukanga whakahauwai, engari he whānuitia te whakamahinga i roto i ngā whenua me ngā rohe he nui ngā whakaritenga tiaki taiao nā te mea ka taea e ia te whakatutuki i te hua whanariki teitei, pērā i te neke atu i te 99.8%.
2. Te tukanga mimiti waikura
Ko te tikanga mimiti waikura he tikanga e waikura tuatahi ana i te whanariki i roto i te hau hiku hei SO2, kātahi ka mimiti i te SO2 me te otinga (te whakarewa rānei), ā, hei whakamutunga ka whakahokia mai i te āhua o te whanariki, te whanariki me te SO2.
He maha ngā tikanga o tēnei momo, ko te nuinga e whakamahia ana mō te tango whanariki i te hau paipa, te maimoatanga rānei i te hau hiku mai i ngā miihini whakarewa me ngā tipu waikawa whanariki, ā, ko te tikanga Wellman Lord e whakamahia ana mō te maimoatanga i te hau hiku Claus.
3. Tukanga Claus pāmahana iti
Ko te hangarau Claus pāmahana iti e tohuhia ana e te tauhohenga Claus i raro i te ira tomairangi whanariki, nō reira e kiia ana hoki ko te tukanga whakaora whanariki i raro i te ira tomairangi. He tukanga tauhohenga exothermic kaha te tauhohenga Claus. Nō reira, he pai te pāmahana iti ki te nekehanga o te taurite ki te ahunga o te whakaputanga whanariki, ka taea te whakapai ake i te whakaora whanariki. E ai ki te whanaungatanga i waenga i te tauhohenga Claus me te wae, ka taea te wehewehe i te tukanga Claus pāmahana iti ki te tukanga Claus pāmahana iti motuhake me te tukanga Claus pāmahana iti whakakotahi.
4. Tukanga waikura tika ā-wāhanga wai
Ko te tukanga whakahāngaitanga tika ā-wāhanga wai he momo hangarau tukanga e whakahāngai tika ana i te H2S hei whanariki taketake. Ko te kaupapa o tēnei tukanga he mimiti i te H2S ki roto i te hau hiku me te otinga whakakorenga whanariki, kātahi ka whakahāngaitia hei whakaputa i te whanariki taketake.
Ngā tawhā hangarau
1. SO2 ≤ 400mg/Nm3 (turanga maroke, 3vol% O2)
2, Te wā whakaputa ā-tau 8000 hāora
3, Ngāwari whakahaere 50% ~ 120%
