Te Marokenga o te Hau Taiao: Ngā Mātāpono, Ngā Tikanga, me te Tirohanga
Mātāpono:He nui te mamaoa wai kei roto i te hau māori tika mai i te puna. Ki te kore e tangohia, ka taea e tēnei wai te whakapūmau i roto i ngā paipa, ka hanga he waikura (he totoka rite ki te hukapapa) ka aukati i te rere, ka puta rānei te waikura ina honoa ki ngā hau waikawa (pēnei i te CO₂, i te H₂S rānei). Ko te whāinga o te whakamaroke he whakaiti i te tohu tomairangi wai ki raro i te pāmahana paipa iti rawa e tumanakohia ana hei ārai i ēnei raruraru.
Ngā Tikanga:E toru ngā tikanga matua e whakamahia ana:
- Ngongo (Te Whakamaroketanga o te Glycol - Tikanga Matua):Ka pā te hau mākū ki tētahi wai whakamaroke wai hygroscopic, ko te Triethylene Glycol (TEG) te tikanga, i roto i tētahi pourewa whakapā (mokomoko). Ka rewa te mamaoa wai ki roto i te glycol. Kātahi ka hangaia anō te glycol whai rawa mā te whakamahana kia kohuatia mai i te wai, ā, ka whakamahia anō.
- Te mimiti (Te maroke o te totoka):Ka haere te hau mā roto i ngā moenga o ngā whakamaroke totoka pērā i te silica gel, te alumina whakahohe, ngā tātari ngota rānei. Ka piri ngā ngota wai ki te mata whānui o te whakamaroke. Ka whakamahia mō ngā whakaritenga tohu tomairangi tino iti, mō ngā tono pēhanga teitei rānei. Ka hangaia anō ngā moenga mā te whakamahi i te hau wera.
- Te whakapūpūtanga:Ka whakamataohia te hau (hei tauira, mā te pouaka whakamātao, te whakawhanui, te mahi tahi rānei me Te mimiti o te TEG i roto i te tukanga "Coldfinger"), ka whakapūmau te mamaoa wai hei pata wai ka wehea.
Ngā Painga:He nui ngā painga o te matewai whai hua:
- Ārai i te Hanganga Waipiro:Ka whakarite i te rere tonu o te hau i roto i ngā paipa me ngā taputapu tukatuka.
- Whakaiti i te Waikura:Ka whakaiti i te waikura e hua mai ana i te wai wai me ngā hau waikawa, ka roa ake te ora o ngā taputapu me te whakarei ake i te haumaru.
- E tutuki ana i ngā Whakatakotoranga Paipa:He mea nui mō te whakatutuki i ngā whakaritenga kirimana mō te ihirangi wai mō te tuku me te hoko hau.
- Ka tiaki i ngā tukanga o raro:Ārai i ngā raruraru i roto i ngā tipu cryogenic (hei tauira, Te whakaputanga LNG) te wāhi e tio ai te wai.
Ngā Tūmanako: Te maroketanga o te glycol kei te noho tonu hei hoiho mahi nā te mea he pai te mahi me te iti o te utu. Ko te whanaketanga ā muri ake nei e arotahi ana ki:
- Ngā Tukanga Glycol Whakarei Ake:Te whakapai ake i te whai huatanga o te whakahoutanga o TEG (hei tauira, a Drizo, Coldfinger) kia iti ake ai ngā ira tomairangi me te iti ake o te ngaronga pūngao me te glycol.
- Ngā Whakamaroke Matatau:Te whakawhanake i ngā tātari ngota ngota pakari ake, kaha ake, me ngā mea mimiti ka taea te whakahou.
- Hangarau kiriuhi:Kei te haere tonu ngā rangahau mō ngā kiriuhi e tuku ana i ngā tapuwae pūngao iti ake pea mō ngā tono motuhake.
- Te Whakatutukitanga Taiao:Ko te whakaiti i ngā tukunga (VOC, BTEX) mai i ngā waeine glycol me te arotau i te whakamahinga pūngao ngā tino kaupapa matua.
- Te Whakamatihiko me te Aunoatanga:Te whakatinana i ngā pūnaha whakahaere matatau mō te mahi tino pai me te tiaki matapae.
He taahiraa nui tonu te maroke o te wai i roto i te tukatuka hau, he mea nui hoki mō te hanga me te kawe hau maori haumaru, whai hua, me te pono puta noa i te ao.
