Design with Simulation on the Separation of Ethanol from Water and Ethanol Azeotropic Mixture Using Chemcad Software
Ethanol and water combines to form azeotrope due to which it becomes very difficult to separate them by ordinary fractionation. Special distillation methods can exploit for separation of the azeotropes into pure components such as pressure-swing distillation, by using separating agent as an entrainer added to the mixture for homoazeotropic distillation, extractive and salt distillation, heteroazeotropic distillation, membrane distillation or adsorptive distillation. In this paper, the separation technique was optimized by simulating with CHEMCAD software. Different types of designs were run in the CHEMCAD software for simulation and modeling of the best separation of ethanol from the mixture. The third design shows around 92% of ethanol separation using the software. The process based on the process parameters such as pressure and temperature; the unit operation parameters such as number of stages of the units and the feed stages etc. This software is more feasible for R&D as well as industry rather than the conventional method of separation.
