Języki publikacji
Abstrakty
Przedstawiono wyniki badań doświadczalnych dotyczące wpływu oporów dyfuzyjnych w fazie ciekłej na proces perwaporacji mieszaniny dwuskładnikowej woda-izopropanol na membranie hydrofilowej PERVAP 1005. Zanalizowano wpływ składu i temperatury fazy ciekłej oraz hydrodynamiki przepływu na wielkość strumienia permeatu, selektywność i współczynnik permeacji. Opracowano model matematyczny procesu umożliwiający wyznaczenie współczynnika wnikania masy w fazie ciekłej dla płaskiego modułu membranowego w laminarnym zakresie przepływu.
Experimental results of the influence of diffusional resistance in the liquid phase on the pervaporation of binary water-isopropanol mixture on the membrane PERVAP 10005.has been presented. The effect of the flow hydrodynamic, composition and temperature of the liquid phase on the permeate flux, selectivity and coefficient of pervaporation was investigated. The model of the process was developed which enables one to calculate the mass-transfer coefficient for a flat membrane module in the laminar flow.
