Ngaphantsi koxinzelelo oluqhubekayo, xa umxube wamanzi otywala ufikelela kwi-95.57% (w / w), iqhezu lomthamo lifikelela kwi-97.2% (v / v), umxube wokubilisa uqulunqwe kuloo ngxingoniso, Oko kuthetha ukusebenzisa indlela eqhelekileyo yokuchithwa kwe-distillation ayikwazi ukufikelela. utywala ubunyulu phezu 97,2% (v/v).
Ukuvelisa i-high-purity anhydrous alcohol, yamkela i-variable pressure adsorption (PSA) ye-molecular sieve, kunye ne-99.5% yoxinaniso ukuya kwi-99.98% (v / v) emva kokuchithwa kwamanzi kunye nokunciphisa. Xa kuthelekiswa ne-ternary ternary azeotropic distillation method, enesiphumo esihle sokuphelelwa ngamanzi emzimbeni, umgangatho wemveliso ephezulu, itekhnoloji ephezulu kunye nokusetyenziswa kwamandla aphantsi.
I-Ethanol dehydration molecular sieve adsorption method bubuchule bokufunxa amanzi e-ethanol yokutya. Ukusebenzisa i-molecular sieve ye-JZ-ZAC, i-molecule yamanzi yi-3A, kunye ne-2.8A, i-molecule ye-ethanol yi-4.4A. Ngenxa yokuba iimolekyuli ze-ethanol zinkulu kuneemolekyuli zamanzi, iimolekyuli zamanzi zinokubhengezwa emngxunyeni, iimolekyuli ze-ethanol azikwazi ukubhengezwa ngaphandle. Xa i-ethanol enamanzi ibhengezwa kakuhle kwisefa yemolekyuli, i-molecular sieve ibhengeza iindawo zamanzi, ngelixa umphunga we-ethanol udlula ibhedi ye-adsorption kwaye ibe yimveliso ye-ethanol ecocekileyo.
