Simulation of Batch Distillation

      The importance of batch distillation process in chemical, petroleum and pharmaceutical industries to separating the liquid mixture into their constituent components. The present work is concerned with developing a computer program using short-cut model and a simulation computer program using rigorous model to analyze multi-components non ideal mixture, multistage batch distillation column using MATLAB version 6.5. The short-cut model has been used to calculate minimum number of stage using Fenske equation and minimum reflux ratio using Underwood equation.

Investigation of Correlations for Prediction of Critical Properties of Pure Component

Prediction of accurate values of critical properties of any pure component is very important because they are often utilized in estimating the physical properties for chemical process design. Experimental measurements of critical properties for components are very difficult. So in order to obtain accurate critical property values, attention has been turned to calculate it using mostly a group contribution method which is difficult method. To overcome this problem efforts where directed to modify or improve equations to calculate critical properties using relatively simple method.

PREDICTION OF PRESSURE DROP IN PACKED BED FOR WATER AND AIR SYSTEMS

 Semi-empirical equations for fluid flow through packed bed have been proposed, depending on statistical fitting of experimental data. Two types of fluids have been used (water and air) separately (single phase flow). Several size distributions of sphere packing materials have been used in the packed bed, and each had been studied separately. Different parameters affecting the pressure drop of fluid flow through
