Preparation Of Zeolite Membrane And Modeling Dehydration Of Organic Compounds On The Pilot-Scale With The Help Of Artificial Neural Network

Nano pore NaA zeolite membranes composed of a continuous intergrowth of NaA zeolite crystals had been synthesized hydrothermally on the surface of a porous tubular support 14 mm outer diameter 25 cm length. Morphology of the supports subjected to crystallization was characterized by Scanning electron microscopy SEM. Separation performance of NaA zeolite membranes was studied for water-Ethanol mixtures using pervaporation PV in cross flow method. The membranes showed good selectivity towards water in the water- Ethanol mixtures. Water permeates faster because of its preferential adsorption into the nano-pores of the hydrophilic zeolite membrane. The membrane exhibits a hydrophilic behavior with a high selectivity towards water and a good flux. Thus the pilot- scale PV plant which produces 5 lh of solvent EtOH at less than 0.2 wt. of water from 90 wt. solvent at 75C has been put into pilot operation. The present study considered the amount of water-alcohol separation within the process of pervaporation with the help of Artificial Neural Network modeling.
