Simulation Of A Sieve Plate Column With Ethanol/water System Using The Nonequilibrium Stage Model

Abstract

An experimental evaluation was made of a distillation column which shows the behavior of temperature and composition profiles along the equipment and the validation of the nonequilibrium stage model. A stainless steel column with eight sieve plates was built and was operated at total reflux. After reaching steady state, the liquid samples and the temperature were taken at each stage in the column and the samples were analyzed using GC. With the data in each stage and with the data obtained from simulations, it was possible to corroborate the model. The results showed that the nonequilibrium stage model reproduces the real conditions of the process.73672
