zeolite and carbon thin films on our commercial ceramic membrane substrate for separation of water through pervaporation and vapor permeation. Due to its aperture size and polar... nature, zeolites, such as NaA, have been selected by us to be used as a dehydration membrane which preferentially permeates water over solvents. By operating at higher feed... temperatures due to its unique material stability, several process advantages would accrue. Interstage heaters become unnecessary or minimized. Evaporative cooling occurs in the modules...
