Investigation the Effects of Operating Parameters in Ethan Dehydration by 3A Molecular Sieve

In this study¡ an industrial unit of ethane dehydration which uses 3A adsorbents molecular sieve was simulated by using of mass¡ energy and momentum equations. For modeling of this process¡ rate of adsorption is approximated by linear driving force expression. The second form of Langmuir isotherm was employed in predicting adsorption equilibrium for water content in gas and solid phases. The mentioned mathematical equations were solved simultaneously by Matlab software. Then the simulation results were validated by using the experimental data and the simulation studies were performed to investigate the effect of changing various process variables¡ such as¡ diameter of absorbent¡ regeneration gas flow rate¡ feed pressure and temperature on water content of the product. The results shows that water content in the product increased by increasing of adsorbent diameter and feed temperature. While water content in the product decreased by increasing feed pressure and regeneration gas flow rate.
