Kana mvura nedoro zvikaramba zvichimanikidzwa, kana musanganiswa wemvura nedoro wasvika 95.57% (w/w), chikamu chevhoriyamu chasvika 97.2% (v/v), musanganiswa wecoboiling unogadzirwa pahuwandu ihwohwo, zvinoreva kuti kushandisa nzira yakajairika yekudiridza hakugone kusvika pakuchena kwedoro kupfuura 97.2% (v/v).
Kuti mugadzire doro rine mvura yakawanda yakachena, shandisai sefa yemasero inoshanduka-shanduka (PSA), ine huwandu hwe99.5% kusvika 99.98% (v/v) mushure mekushaya mvura uye kunyorova. Kana tichienzanisa nenzira yechinyakare ye ternary azeotropic distillation, ine mhedzisiro yakanaka yekushaya mvura, mhando yepamusoro yechigadzirwa, tekinoroji yepamusoro uye kushandiswa kwesimba shoma.
Nzira yekunyudza ethanol kubva mumvura nemakemikari musefa yemakemikari inzira yekunyudza mvura yeethanol. Uchishandisa sefa yemakemikari yeJZ-ZAC, molekyuru yemvura i3A, uye molekyuru yeethanol i2.8A i4.4A. Nekuti mamorekyuru eethanol akakura kupfuura mamorekyuru emvura, mamorekyuru emvura anogona kunyudzwa mugomba, mamorekyuru eethanol haakwanise kunyudzwa anobviswa. Kana ethanol ine mvura yanyudzwa zvakanaka nepakati pesefa yemakemikari, sefa yemakemikari inonyudza zvikamu zvemvura, nepo ethanol vapor ichipfuura nepamubhedha we adsorption yova chigadzirwa cheethanol chaiyo.
Zvigadzirwa zvine chekuita nazvo:JZ-ZAC molecular sefa
