Ngaphansi kwengcindezi eqhubekayo, lapho ingxube yamanzi e-alcohol ifinyelela ku-95.57% (w / w), ingxenyenamba yevolumu ifinyelela ku-97.2% (v / v), ingxube yokubilisa yenziwa kulokho kuhlushwa, Okusho ukuthi ukusebenzisa indlela evamile yokuphuza i-distillation ayikwazi ukufinyelela. ukuhlanzeka kotshwala ngaphezu kwama-97.2% (v/v).
Ukuze ukhiqize utshwala obungenamanzi obuhlanzekile obuphezulu, sebenzisa i-variable pressure adsorption (PSA) i-molecular sieve, nge-concentration engu-99.5% kuya ku-99.98% (v/v) ngemva kokuphelelwa amandla kwamanzi nokufingqa.Uma kuqhathaniswa nendlela yendabuko ye-ternary azeotropic distillation, enomthelela omuhle wokuphelelwa amanzi emzimbeni, ikhwalithi yomkhiqizo ophezulu, ubuchwepheshe obuthuthukisiwe kanye nokusetshenziswa kwamandla okuphansi.
I-Ethanol dehydration molecular sieve adsorption method iyindlela yokumunca amanzi e-ethanol yokudla.Isebenzisa isisefo se-molecular ye-JZ-ZAC, i-molecule yamanzi ingu-3A, bese i-2.8A, i-ethanol molecule ingu-4.4A.Ngenxa yokuthi ama-molecule e-ethanol makhulu kunama-molecule amanzi, ama-molecule amanzi angakhangiswa emgodini, ama-molecule e-ethanol awakwazi ukukhangisa awabandakanyi.Lapho i-ethanol enamanzi ikhangisa ngobunono ngesisefo samangqamuzana, isisefo semolekyuli sikhanga izingxenye zamanzi, kuyilapho umhwamuko we-ethanol wedlula umbhede we-adsorption futhi uba umkhiqizo we-ethanol omsulwa.
