Te waeine denitrification ka tangohia te hauota mai i te hau māori hei whakarite mō te tuku paipa. E ai ki ngā raraunga a te Whare Rangahau Hau Maori, 17% o ngā rahui hau maori i te Hononga o Amerika he nui te ihirangi hauota. Ko te nuinga o ngā paerewa paipa e kī ana kia iti iho i te 4% te ihirangi hauota i roto i te hau maori. Ko te hau maori he nui te hauota ka noho pūmau nā te mea kāore e taea te kawe ki te mākete mā roto i ngā paipa. Mena he nui rawa te hauota i roto i te paipa, tera pea ka purua te hau, ka ngoikore rānei te tahunga. Ka whakaitihia hoki e te hauota te uara wera o te hau, ka heke te BTU me tōna uara.
Nā te mea he rite te rahi o te ngota ngota o te hauota (N2) me te methane (CH4), he iti hoki ngā pūmau dielectric, ā, kāore hoki he tauhohenga whiriwhiri, pērā i te hauhā waro, te hauwai sulfide rānei i roto i ngā waeine amine, he uaua te wehewehe hangarau o te denitrification.
Ko te mimiti pēhanga (PSA), te wehenga pāmahana iti me te mimiti hinu kikokore kua whakamahia katoa hei tango i te hauota mai i te hau maori.
Ka whakamahia e te adsorption swing pressure (PSA) he adsorbent hei whiriwhiri wehea te hauota mai i te methaneKātahi ka hangaia anō te hau mai i te mea mimiti mā te whakakotahitanga o ngā huringa pēhanga me te wera. Ka whakamahia te PSA mō te whakamaroke hau, te tango i te hauhā waro, te whakakorenga i te waikawa me te whakahaere i te ira tomairangi warowaihā.
Ko te wehenga cryogenic e whakamahi ana i te Wehenga Thermodynamic cryogenic. I runga i ngā pūwāhi kohua whakatairite o te methane (- 259° F) me te hauota (- 320° F). I te whakamataotanga o te ranunga, ka whakapūpū te methane i mua i te hauota, ā, ka wehea ngā mea e rua.
