Investigation into Ethanol Purification Using Polymeric Membranes and a Pervaporation Process
The dehydration of organic solvents is important in the production of solvents on an industrial scale. A mathematical model for the simulation of a membrane separation process was developed for the dehydration of ethanol using pervaporation. The model was capable of predicting mass transfer along with momentum transfer in the feed and membrane compartments. A comprehensive computational fluid dynamics simulation was developed for the rational design of a bioethanol purification system using a pervaporation process by tailoring the hydrodynamics of the process. The process involves the removal of water from a water/ethanol liquid mixture using a dense polymeric membrane. The model domain was divided into two compartments comprising the feed and the membrane. To describe water transport in the feed solution, the Maxwell?Stefan approach was used, whereas for mass transfer inside the membrane the molecular diffusion mechanism was adopted. The governing equations were solved numerically by using a finite element method. The model was capable of predicting mass transfer along with momentum transfer in the feed and membrane compartments.
