Kupu Whakataki
Mā ngā tukanga whakamaroketanga glycol Hengzhong ka tangohia te mamaoa wai mai i te hau māori, he taputapu maimoatanga hau māori, e āwhina ana ki te aukati i te hanganga waikura me te waikura, ā, ka whakanui ake i te whai huatanga o ngā paipa.
Ka hangaia, ka tāutahia hoki e ngā miihini o Hengzhong ngā pūnaha whakamaroke katoa, tae atu ki ngā pūnaha whakamaroke ritenga me ngā pūnaha paerewa, ngā kōwae purenga glycol, ngā wae werohanga glycol, me ngā pūnaha whakaora hau tango.
Kei te wātea hoki tētahi kaupapa tautoko katoa hei whakaea i ngā āhuatanga katoa o ō raruraru matewai.
Te tukanga mahi
He māmā noa te tukanga whakamaroke glycol—ka pā te hau mākū ki te glycol maroke, ā, ka mimiti te glycol i te wai mai i te hau. Ka uru te hau mākū ki te pourewa i te raro. Ka rere te glycol maroke i te pourewa mai i runga, mai i te paepae ki te paepae, mā roto rānei i ngā rauemi tākai.
Tono
Te tango i te wai; te benzene, te toluene, te ethylbenzene, me te xylene (BTEX); me ētahi atu matū waro pūngāwerewere (VOC) mai i ngā awa hau māori
Te maroketanga o te hau māori
Painga
Whakarei ake i te whānui o te mahi
He iti ake ngā utu whakahaere ki te whakataurite ki ngā whakamaroke tikanga
He iti ake te capex ki te whakataurite ki ngā pūnaha moenga totoka
Te whakaiti i ngā wā hanga me te wā whakatūnga mā te tuku waeine paerewa (e wātea ana hoki ngā waeine ritenga)
Te whakangawari i te takai o ngā pūnaha ranu
Taupoki mirumiru
Mā te whirihoranga taupoki mirumiru motuhake ka whakanui ake i te pānga o te hau/glycol, ka tangohia te wai ki ngā taumata i raro iho i te 5 lbm/MMcf. Ka taea te hanga i ngā pūnaha kia eke ki ngā taumata ki raro iho i te 1 lbm/MMcf. Ka wehe te hau maroke i te pourewa i te tihi ka hoki ki te paipa, ka haere rānei ki ētahi atu wae tukatuka.
Ka ārai te glycol whai wai i te pourewa i raro, ka haere ki te pūnaha whakapūmau anō. I roto i te pūnaha whakapūmau anō, ka tātarihia te glycol mākū i ngā poke, ka whakamahanahia ki te 204 degC. Ka puta te wai hei mamaoa, ā, ka hoki te glycol parakore ki te pourewa, ka pā anō ki te hau mākū.
Ka mahi pono te pūnaha katoa, kāore he tangata e tirotirohia ana. Ka aroturukihia e ngā kaiwhakahaere ngā pēhanga, ngā pāmahana, me ētahi atu āhuatanga o te pūnaha kia pai ai te mahi.
