Pasi pekumanikidzwa nguva dzose, kana doro-mvura musanganiswa wasvika 95.57% (w / w), chikamu chevhoriyamu chinosvika 97.2% (v/v), musanganiswa wekubikira unoumbwa pakusangana ikoko, Zvinoreva kuti kushandisa yakajairika distillation nzira haigone kusvika. doro kuchena kupfuura 97,2% (v/v).
Kugadzira yakakwira-kuchena anhydrous doro, tora variable pressure adsorption (PSA) molecular sieve, ine 99.5% concentration kusvika 99.98% (v / v) mushure mekupera mvura uye condensation.Kuenzaniswa neyechinyakare ternary azeotropic distillation nzira, ine yakanaka dehydration mhedzisiro, yakakwira chigadzirwa mhando, tekinoroji yepamusoro uye yakaderera simba rekushandisa.
Ethanol dehydration molecular sieve adsorption method inzira yekunwa mvura yefood ethanol.Uchishandisa sefa yemolecular yeJZ-ZAC, iyo molecule yemvura i3A, uye iyo 2.8A, ethanol molecule i4.4A.Nekuti mamorekuru ethanol akakura kupfuura mamorekuru emvura, mamorekuru emvura anogona kuvharirwa mugomba, mamorekuru ethanol haakwanise kushambadza haana kubatanidzwa.Kana iyo ethanol ine mvura yakashambadza zvakatsvinda kuburikidza nesefa yemamorekuru, sefa yemolecular inoshambadza zvikamu zvemvura, nepo ethanol vapor ichipfuura mubhedha weadsorption uye inova yakachena ethanol chigadzirwa.
