Pervaporation is a proven technology that overcomes distillation to produce high-quality ethanol. The process is modeled and simulated in the literature, but the model’s accuracy with industrial data is rarely discussed. In this work, a commercial pervaporation membrane was modeled and simulated in UniSIM® (R490) to purify ethanol from water after the azeotrope point of distillation. The pervaporation system was developed manually using a component splitter, adjust functions, and a spreadsheet. Results show that the simulation calculations were acceptable and differed from pilot-plant data by 4.6%. A correction factor was used to reduce the error further to 0.7%.
