Using of Conductivity Method for Trace Water Determination in Dehydration of Ethanol by Absorbent Zeolite 3A

The aim of this research was to use a conductivity method for trace water determination in ethanol. A main challenge in producing the ethanol concerned the production cost which was largely contributed by the process of water removal. For this purpose, the water content was determined by measuring conductivity of solution, containing same amount of sodium chloride added for all solutions. An experimental setup was designed by employing a commercial adsorbent type of zeolite 3A. As a results, in the solutions with different of water (from 6% to 0.5% wt.), the high value correlation curve for the regression line as well as low limits of detection was achieved which indicates that this method is a useful tool for the determination of the trace amounts of water in dehydration of ethanol process.
