Te tukanga whakaora o ngā warowaihā māmā mai i te hau e pā ana ki ngā mara hinu (1)
Te te whakaora i ngā warowaihā māmā He tukanga nui te tangohanga mai i te hau e pā ana ki ngā mara hinu i roto i te umanga hinu me te hau. Ko te hau e pā ana, e kitea pinepine ana i te taha o te hinu mata, kei roto ngā wāhanga nui pērā i ngā wai hau māori (NGL) me te hau hinu waikura (LPG). Mā te tangohanga mai i ēnei warowaihā māmā, ehara i te mea ka whakanui ake i te uara o te rerenga hau engari ka āwhina hoki ki te whakaiti i ngā tukunga hau kati kōtuhi. I roto i tēnei tuhinga, ka tūhuratia e mātou te hiranga o te tangohanga mai o te NGL me te LPG mai i te hau e pā ana me ngā hangarau e whai wāhi ana ki tēnei tukanga.
Te whakaora NGL mai i te hau e pā ana kei roto ko te wehenga me te tango i ngā wai hau māori pērā i te ethane, te propane, me te butane. He nui te uara arumoni o ēnei wāhanga, ā, e whakamahia ana hei rauemi whāngai mō ngā tipu hinu-matū, tae atu ki te hanga kirihou, rapa hangai, me ētahi atu hua ahumahi. Ko te whakaora o NGL mai i te hau e pā ana he mea nui hei whakanui ake i te pūmanawa ōhanga o te awa hau me te whakaiti i te moumou rauemi whai hua.
Ko te whakamārama poto o te tukanga ko:
1) Pūnaha whakaranu me te whakanui hau māori
1) Whakaahuatanga tukanga
Ka pēhia te hau whāngai ki te 0.3 MPaG, kātahi ka konatunatua ki te awa Pēhanga Iti, kātahi ka pēhia ki te 3.9 MPaG. Kātahi ka konatunatua te awa whakauru ki te Pēhanga Teitei, ka tomo ki te taputapu o raro.
2) Ngā tawhā hoahoa
Te kaha tukatuka hau whāngai:
Pēhanga Teitei: 12500 Nm3/h;
Pēhanga Iti: 16166.7 Nm3/h;
2) Pūnaha whakamaroke hau māori
1) Whakaahuatanga tukanga
He maha ngā wā ka pā mai ngā hua kino ki te hau māori: ka taea e te makuku me te hau māori te hanga i ngā hauwai, i te huka rānei hei aukati i ngā paipa i raro i ētahi āhuatanga.
Ka whakamahia e te tātari ngota te tikanga mimiti hau māori. Nā te mea he kaha te whiriwhiri mimiti o te tātari ngota, ā, he nui ngā āhuatanga mimiti i raro i te pēhanga iti o te kohu wai, ka whakamahia e tēnei taputapu te tātari ngota 4A hei mimiti mimiti.
Ka whakamahia e tēnei waeine he tukanga pourewa-rua hei mimiti i te makuku, ka whakamahia te tikanga TSA hei tātari i te makuku e mimitihia ana i roto i te tatari ngota, ā, ka whakamahia te tikanga whakapūpū hei whakapūpū me te wehe i te makuku kua tangohia mai i te mea mimiti.
2) Ngā tawhā hoahoa
Te kaha tukatuka hau whāngai 70 × 104 Nm3/rā
Pēhanga mimiti 3.5MPaG
Te pāmahana mimiti 35 ℃
Pēhanga whakaora 3.5MPaG
Te pāmahana whakaora ~260 ℃
Hinu wera pūtake whakaora
Te ihirangi o H2O i roto i te hau parakore
