Pansi pa kupanikizika kosalekeza, pamene osakaniza mowa-madzi afika 95.57% (w / w), voliyumu kachigawo kufika 97.2% (v / v), coboiling osakaniza aumbike pa ndende, kutanthauza ntchito wamba distillation njira sangathe kufika. mowa chiyero kuposa 97.2% (v/v).

Kuti mutulutse mowa wambiri wa anhydrous mowa wambiri, tengerani kusintha kwa ma molekyulu adsorption (PSA), ndi 99.5% ndende mpaka 99.98% (v / v) pambuyo pa kutaya madzi m'thupi ndi condensation.Poyerekeza ndi njira yachikhalidwe ya ternary azeotropic distillation, yokhala ndi zotsatira zabwino za kutaya madzi m'thupi, mtundu wapamwamba wazinthu, ukadaulo wapamwamba komanso kugwiritsa ntchito mphamvu zochepa.

Mowa dehydration molecular sieve adsorption njira ndi njira kuyamwa madzi a chakudya Mowa.Pogwiritsa ntchito sieve ya molekyulu ya JZ-ZAC, molekyulu yamadzi ndi 3A, ndipo 2.8A, molekyulu ya ethanol ndi 4.4A.Chifukwa mamolekyu a ethanol ndi akulu kuposa mamolekyu amadzi, mamolekyu am'madzi amatha kulowetsedwa mu dzenje, mamolekyu a ethanol sangathe kutsatiridwa.Pamene madzi munali Mowa adsorbed mwaukhondo kudzera maselo sieve, maselo sieve adsorbs madzi mbali, pamene Mowa nthunzi akudutsa adsorption bedi ndi kukhala koyera Mowa mankhwala.

Zogwirizana nazo:JZ-ZAC molecular sieve
