MODELING AND SIMULATION OF OBI COLUMN FOR WATER-ACETONE-TOLUENE SYSTEM

Abstract

There is hardly any chemical process, which does not involve separation of liquid mixtures or recovery of valuable components from the reaction products. Liquid-liquid extraction processes have been increasingly used with advantage in these operations. The development of sound methods of equipment design has present trend. In recent times the approach to data interpretation has undergone a shift towards better modeling of transport processes yielding new methods of scaleup and design. Liquid extraction modeling demonstrates the performance of extraction equipment which includes concentration profile hold up of dispersed phase along the column height, fluid dynamics etc. In the present study the modeling of extraction column has been carried out which describes the concentration profile of solute in the dispersed phase and continuous phase. In this thesis, a one-dimensional dynamic and steady state mathematical models have been developed for the simulation of a Kiihni extraction column. The effect of different parameters on the performance of the column has been discussed. To solve the model equations, input data physical properties of the system chosen and correlation are taken from the literature. The model equations are solved for step response dynamic, steady state conditions by using MATLAB 6.5 software. The model gives the results of Kiihni column for water acetone toluene system. The obtained results from the model equation have been validated with experimental data available in the literature.
