I raro i te pēhanga pumau, ina tae te ranunga waipiro-wai ki te 95.57% (w/w), ka tae te wāhanga rōrahi ki te 97.2% (v/v), ka puta he ranunga kohua-ko i taua kukū. Ko te tikanga, mā te whakamahi i te tikanga whakahoro noa, kāore e taea te eke ki te parakore o te waipiro neke atu i te 97.2% (v/v).
Hei whakaputa waipiro kore-waikawa teitei-parakore, ka whakamahia te tātari ngota ngota pēhanga rerekē (PSA), me te kukū 99.5% ki te 99.98% (v/v) i muri i te maroke me te whakatōtō. Ki te whakataurite ki te tikanga whakamaroke azeotropic ternary tuku iho, he pai te pānga maroke, he kounga hua teitei, he hangarau matatau me te iti o te whakapaunga pūngao.
Ko te tikanga mimiti irahiko tātari ngota wai whakamaroke etanoru he tikanga mō te mimiti i te wai o te etanoru whāngai. Mā te whakamahi i te tātari ngota o JZ-ZAC, ko te ngota wai he 3A, ā, ko te ngota etanoru 2.8A he 4.4A. Nā te mea he nui ake ngā ngota etanoru i ngā ngota wai, ka taea te mimiti i ngā ngota wai ki roto i te kōhao, kāore e taea te mimiti i ngā ngota etanoru. Ina mimiti pai te etanoru kei roto te wai mā roto i te tātari ngota, ka mimiti te tātari ngota i ngā wāhanga wai, i te wā e whiti ana te kohu etanoru i te moenga mimiti ka huri hei hua etanoru parakore.
