Steady state and dynamic simulation of multi-stage flash desalination plants: A case study

A mathematical model and its solution procedure are developed to simulate the steady-state and dynamic behaviour of multistage hash desalination plants. The steady-state and dynamic models are based on the same set of equations and are of the same order. The solution procedure developed is numerically stable and easy to implement. The steady state model is used to predict the operating parameters of a particular plant. A close agreement between the predicted values and the measured data from the actual plant has been observed. The transient response of the plant for step changes in input variables has been obtained. The computed response of the plant is comparable to the operating records of a real plant.
