Funcionamiento de una membrana de zeolita 4-A comercial en la deshidratación de disolventes industriales mediante pervaporación

Abstract

The performance of a commercial zeolite NaA pervaporation membrane supplied by Smart Chem., U.K.) was studied with respect to the dehydration of industrial mixtures of tetrahydrofurane/water (CH2O ≤7.9 wt.%) and acetone/water (CH2O≤3.25 wt.%). The influence of water concentration and temperature in the range 40 ºC - 65 ºC on fluxes and selectivities was described. The stability of the membrane in consecutive operation cycles is also reported
