Parametric simulation of MED-TVC units in operation

The main goal of this paper is to simulate the performance of Multiple Effect Desalination (MED) units in operation to predict the influence of variation of different input parameters on the amount of product, GOR value and thermodynamic condition of the unit during the operation. Therefore, for a given system with specified geometry, including thermocompressor, heat transfer area of the effects and condenser, mass and energy balance equations can be written and solved simultaneously in a set of nonlinear equations for different parts of the system. The results obtained by the simulation code are compared the experimental data obtained from an MED-TVC unit installed in Assaluyeh city in Kavian petrochemical company. There is a good agreement between the calculated results and the experimental data. Results show that the variation in the seawater temperature and the scaling amount around the tubes of the first effect have the most influence on variation in production rate.
