Ka whakamahia te hauwai i roto i te maitai, te whakarewa, te ahumahi matū, te hauora, te ahumahi marama, te hanga whare, te hikohiko me etahi atu mara. Ko te hangarau whakahou Methanol ki te whakaputa hauwai he pai ake te iti o te haumi, te kore parahanga, me te ngawari te whakahaere. Kua whakamahia nuitia ki nga momo tipu hauwai parakore katoa.
Whakaranuhia te methanol me te wai i roto i tetahi ohanga, pehi, wera, whakangohu me te whakawera i te rauemi ranunga kia tae ki tetahi pāmahana me te pehanga, katahi ka puta mai te whakakorikori, te tauhohenga methanol cracking me te tauhohenga huringa CO ka mahi i te wa ano, ka whakaputa he te ranunga hau me te H2, CO2 me te iti o te toenga CO.
Ko te tukanga katoa he tukanga endothermic. Ko te wera e hiahiatia ana mo te tauhohenga ka tukuna ma te tohanga o te hinu kawe wera.
Hei whakaora i te kaha o te wera, ko te hau ranunga i hangaia i roto i te reactor ka whakawhiti wera me te wai ranunga rauemi, katahi ka whakamatao, ka horoia ki te pourewa purenga. Ka wehea te wai ranunga mai i te whakamahana me te horoi horoi i roto i te pourewa purenga. Ko te hanganga o tenei ranunga ko te wai me te methanol te nuinga. Ka whakahokia ki te taika rawa mo te hangarua. Ka tukuna te hau kapiti tohu ki te wae PSA.
