Te Tātari i te Whakapaunga Pūngao Matua me ngā Pānga Taiao i roto i te Hanganga o te Coke Hinu Whakapūkara
I. Ngā Tukanga Matua mō te Whakamahinga Pūngao
- Maimoatanga Whakakāwhata Mahana-Tiketike
Ko te whakakāwhata te tukanga matua, me eke ngā pāmahana ki te 2,800–3,000°C hei huri i te waro kore-kāwhata i roto i te kōka hinu hei hanganga karaihe kāwhata. He tino nui te kaha e whakamahia ana i tēnei wāhanga, ā, e 6,000–8,000 kWh ia tana o te hiko e pau ana i ngā oumu Acheson tuku iho. Ka whakaitihia tēnei e ngā oumu poutū hou ki te 3,000–4,000 kWh ia tana, ahakoa ko ngā utu pūngao tonu te 50%–60% o ngā whakapaunga whakaputa katoa. - Ngā Huringa Whakamahana me te Whakamatao Roa
E 5–7 ngā rā e pau ana i ia puranga o ngā tukanga tuku iho, engari i ngā oumu hou, ka whakapotoa tēnei ki te 24–48 hāora. Heoi anō, e 480 hāora tonu te roa o te whakamatao hau māori e hiahiatia ana mō te whakamatao. Ko te whakaoho me te whakaweto pinepine i ngā oumu ka hua ake he moumou pūngao wera, ka nui ake te whakapaunga pūngao. - Te Whakamahinga Pūngao i roto i ngā Tukanga Āwhina
- Te Kuru me te Huri: Me kuru te kōka hinu ki te rahi o te matūriki o te 10–20 mm, ā, he nui te pūngao hiko e pau ana i te huri.
- Whakama (Horoi Waikawa): Ka whakamahia ngā matū hei tango i ngā poke, hei whakanui ake i te uaua o te tukanga, me te kore e pau te hiko.
- Te Parenga Hau: Ka tukuna tonutia ngā hau kore mahi pēnei i te argon me te hauota hei ārai i te waikura, ā, me whakahaere tonu ngā taputapu tuku hau.
II. Tātari Pānga Taiao
- Ngā Tukunga Hau Para
- Wāhanga Pāmahana-Iti (Pāmahana Rūma–1,200°C): Ka tauhohe te waikura konupūmā (CaO) i roto i te rauemi whakakī (coke hinu kua whakapūkaratia) ki te waro hei whakaputa i te hauota waro (CO), i te wā e whakaputa ana te pirau wera i te methane (CH₄) me ētahi atu tukunga warowaihā.
- Wāhanga Pāmahana-Teitei (1,200–2,800°C): Ka pirau te whanariki, te pungarehu, me ngā mea pūngāwerewere, ka puta he matūriki me te hauhā whanariki (SO₂). Ki te kore he maimoatanga whai hua, ka whai wāhi ngā tukunga SO₂ ki te ua waikawa, ko ngā matūriki ia ka whakaiti i te kounga o te hau.
- Ngā Mahi Whakaiti: Mā te whakakotahitanga o ngā wehewehe awhiowhio, ngā horoi kawakore e toru-wāhanga, me ngā tātari whare putea ka tutuki i ngā paerewa ture ngā tukunga kua tukatukahia.
- Wai Para me te Para Totoka
- Wai Para: Ka puta he wai para waikawa me whakakore te wai horoi waikawa, engari kei roto i te wai whakamatao taputapu ngā poke hinu e hiahia ana kia wehea, kia whakaorangia anō hoki.
- Para Totoka: Ko te rauemi whakakī kua āraia, kāore i te pai te ātete, ka kohia ki roto i te putea hei hoko, hei tuku rānei ki te whenua ururua, ka tūpono ai te poke o te oneone mēnā ka hē te whakahaere.
- Parahanga Puehu
Ka puta te puehu i te wā e kuru ana, e tātari ana, e horoi ana i te oumu. Ki te kore he pūnaha kohikohi kua kati, ka tūpono te hauora o ngā kaimahi, ka poke hoki te taiao.
Ngā Mahi Whakahaere: Ka hopukina te puehu mā te whakamahi i ngā kerēne momi, ngā taupoki, me ngā tātari whare putea i mua i te tukuna mā roto i ngā puranga hau. - Te Whakamahinga Rauemi me ngā Tukunga Waro
- Ngā Rauemi Wai: He nui te wai e whakamahia ana hei whakamatao me te horoi, ā, ka nui ake te ahotea o te wai i ngā rohe maroke.
- Hanganga Pūngao: Ko te whakawhirinaki ki te hiko e ahu mai ana i te wahie pūmua ka hua ake ngā tukunga CO₂. Hei tauira, ko te hanga i te kotahi tana o ngā irahiko karāpeti ka pau te 1.17 tana o te waro paerewa, ka piki ake te tapuwae waro.
III. Ngā Rautaki Whakautu Ahumahi
- Ngā Whakapai Ake Hangarau
- Whakatairangahia ngā oumu poutū hou hei whakapoto i ngā huringa me te whakaiti i te whakapaunga hiko (ka heke te whakamahinga hiko ki te 3,500 kWh ia tana).
- Whakamahia te hangarau whakakāwhata ngaruiti mō te whakamahana tere rawa (<1 hāora) me te tuku pūngao arotahi.
- Te Whakahaere Taiao
- Te Maimoatanga Hau Para: Ngā tukunga tahunga i ngā pāmahana iti, ā, ka whakamahia he kohinga kua kati me te purenga maha-wāhanga i ngā pāmahana teitei.
- Te Hangarua Wai Para: Whakatinanahia ngā pūnaha whakamahi anō wai hei whakaiti i te horomitanga o te wai māori.
- Te Whakarei ake i te Para Totoka: Te whakamahi anō i ngā rauemi whakakī iti iho i te paerewa hei whakakaha waro mō ngā tipu maitai.
- Kaupapahere me te Mahi Tahi Ahumahi
- Kia tutuki ngā ture pērā i teTure Ārai me te Whakahaere i te Parahanga HaumeTure Ārai me te Whakahaere i te Parahanga Waiki te whakatinana i ngā paerewa tukunga tino pakari.
- Whakatairanga i ngā kaupapa rauemi anode whakauru mā te hanga i te kaha whakakāwhata ā-roto hei whakaiti i te whakawhirinaki ki ngā kaiwhakarato o waho me te whakaiti i te parahanga e pā ana ki te kawe waka.
IV. Whakamutunga
He tukanga tino nui te kaha me te poke o te hanga kōka hinu kua whakakāwhatia, ā, ko te whakapaunga kaha e aro ana ki te whakakāwhatia i te pāmahana teitei me ngā pānga taiao e pā ana ki te hau para, te wai, te para totoka, me te poke puehu. Kei te whakaitihia e te umanga ēnei pānga mā roto i ngā whanaketanga hangarau (hei tauira, ngā oumu tonu, te whakamahana ngaruiti), te whakahaere taiao (te purenga maha-wāhanga, te hangarua rauemi), me te whakataurite kaupapa here (ngā paerewa tukunga, te whakaputa whakauru). Heoi, ko te arotau tonu o ngā hanganga pūngao—pērā i te whakauru i te hiko whakahou—he mea nui tonu kia tutuki ai te whanaketanga pumau.
