摘要

This study describes the mathematical model that used for the prediction of the performance of the multi-stage flash plant (MSF) systems under steady state conditions. The developed model based on the mass, heat, and energy balance. The governing equations describe the behavior of temperatures, brine, and product streams within the flashing stage. The losses, densities, enthalpies, and other properties are (accounted) for the model. This model consists of sets of algebraic equations. The proposed model was validated by another data from previous models and by an actual data from existing plants. This model focuses on the evaluation of flow rate and temperatures profile. This model can be used for small and large capacity plants that vary in the range of 5,000-77,760 m~3/d. Through this study, both the specific heat transfer area and the weir load vary in the range of 175-300 m~2/kg/s and 150-310kg/s/m, respectively, also the stage width varies up to 25 m and the stage length varies in the range of 2-6 m.
