N'okpuru nrụgide mgbe niile, mgbe ngwakọta mmiri na-aba n'anya ruru 95.57% (w / w), akụkụ nke olu ruru 97.2% (v / v), ngwakọta ngwakọta na-emepụta na ntinye ahụ, nke pụtara na iji usoro distillation nkịtị enweghị ike iru. mmanya na-aba n'anya karịrị 97.2% (v/v).

Iji mepụta mmanya anhydrous dị elu nke dị elu, were sieve molecular na-agbanwe agbanwe (PSA), yana ntinye 99.5% ruo 99.98% (v / v) mgbe akpịrị ịkpọ nkụ na condensation gasịrị.E jiri ya tụnyere usoro ternary azeotropic distillation nke ọdịnala, nwere mmetụta akpịrị ịkpọ nkụ dị mma, ogo ngwaahịa dị elu, teknụzụ dị elu na ike dị ala.

Ethanol akpịrị ịkpọ nkụ molecular sieve adsorption usoro bụ usoro maka itinye mmiri nke ethanol ndepụta.N'iji sieve molekụla nke JZ-ZAC, molekul mmiri bụ 3A, na 2.8A, molekul ethanol bụ 4.4A.N'ihi na ethanol molekul ibu karịa mmiri molekul, mmiri molekul nwere ike adsorbed n'ime oghere, ethanol molekul enweghị ike adsorb na-ewepụ.Mgbe ethanol nwere mmiri na-agbasa nke ọma site na sieve molecular, sieve molecular na-eme ka akụkụ mmiri ahụ dị, ebe vapor ethanol na-agafe akwa mgbasa ozi wee ghọọ ngwaahịa ethanol dị ọcha.
