摘要：

The pervaporation dehydration of diethylene glycol using ceramic tubular membranes with a hydrophilic selective layer formed from HybSi material was experimentally studied. The experiments were carried out over the process temperature range of 70-90A degrees C at pressures in the permeate part of membrane unit in the range of 5-30 mm Hg and at diethylene glycol concentrations in the range of 93.5-99.8 wt %. Dependences of the membrane surface area required for the dehydration of diethylene glycol over a predetermined range of concentrations on productivity, process temperature, and vacuum were determined.
