Ko ngā tikanga whakaora matua ko te mimiti, te mimiti hinu me te wehenga hauhautanga.
He rite te kaupapa o te tikanga mimiti ki te tukanga whakamaroke mimiti o te tātari ngota rua o te pourewa;
Ko te tikanga mimiti hinu he tikanga hei wehewehe i ngā hau hauwaiwai rerekē i runga i te rerekētanga o te wairewatanga o ia wāhanga i roto i te hinu kua mimitihia;
Ko te tikanga wehewehe hauhautanga he tikanga e whakamahi ana i ngā āhuatanga o ngā pāmahana hauhautanga rerekē o ngā wāhanga hauwaiwai i roto i te hau māori hei whakamatao i te hau māori ki tētahi pāmahana motuhake mā te pouaka whakamātao, kia taea ai te whakapūmau me te wehe i te hauwaiwai he teitei ake te kohua, ā, kia wehewehea ai te hauhautanga hei hua whai tohu.
Ko te whakamatao e pā ana ki te whakamahinga o ngā tikanga horihori hei hanga i te hangarau pāmahana iti (i raro iho i te pāmahana o te taiao). He hononga tata te pūnaha whakamatao ki te umanga hau māori, e whakamahia ana mō te whakaora i te warowaihā māmā, te whakahaere i te tohu tomairangi warowaihā, te tango hau māori wai (LNG) me te hau māori helium, te wehenga CO2 me ētahi atu tukanga.
I nāianei, ko te whakamatao pēhanga mamaoa, te whakamatao whakawhanui whakateretere, te whakamatao whakawhanui, te whakamatao wehewehe wera me te whakamatao awhiowhio hau e whakamahia whānuitia ana i roto i te tukanga whakaora waro māmā.
Ka taea te wehewehe i te tikanga mimiti hinu ki te tikanga mimiti hinu pāmahana noa me te tikanga mimiti hinu matao i runga i ngā pāmahana whakahaere mimiti rerekē. Ko te pāmahana whakahaere o te tikanga mimiti pāmahana noa he pāmahana noa, he iti iho rānei i te pāmahana noa, e whakamahia ana i roto i ngā waeine iti me te rahi waenga, ko te kaupapa matua ko te whakaora i te C3+. Ko te tikanga mimiti hinu matao he whakakotahitanga o te hinu me te pouaka whakamātao. Ka taea e ia te whakaora i ngā hauwaiwaro māmā C2+ mā te whakatio i te hau kua tukatukahia me te mimiti i te hinu matao ki te 0~40 ℃. Ka taea e te tere whakaora o te C3+ te eke ki te 85%~90%. He mea whakamahi noa i roto i ngā tipu tukatuka hau maori nui.
E ai ki te hanganga o te hau māori me te nui o te whakaoranga o te hauwaiwai wai, ka taea te wehewehe i te wehenga hauhautanga ki te wehenga matao papaku, te wehenga matao hōhonu me te wehenga matao waenga.
Ko te kaupapa matua o te wehenga whakamatao papaku ko te whakaora i te propane (C3), ā, ko te pāmahana whakamatao he 15~-25 ℃ te tikanga;
Hei whakaora i te ethane (C2) i roto i te wehenga cryogenic, me neke atu te tere whakaora propane i te 90%, ā, me noho te pāmahana pouaka whakamātao mai i te – 90℃ ki te -100℃; ko te pāmahana o te wehenga whakamatao i te nuinga o te wā ko te – 30 ~ - 60℃. I ētahi wā ka whakarōpūtia te wehenga whakamatao hei wāhanga wehenga cryogenic, e kiia ana ko te tukanga wehenga whakamatao.
