yes / This work describes how the design and operation parameters of the Multi-Stage
Flash (MSF) desalination process are optimised when the process is subject to variation in
seawater temperature, fouling and freshwater demand throughout the day. A simple
polynomial based dynamic seawater temperature and variable freshwater demand
correlations are developed based on actual data which are incorporated in the MSF
mathematical model using gPROMS models builder 3.0.3. In addition, a fouling model
based on stage temperature is considered. The fouling and the effect of noncondensable
gases are incorporated into the calculation of overall heat transfer co-efficient for
condensers. Finally, an optimisation problem is developed where the total daily operating
cost of the MSF process is minimised by optimising the design (no of stages) and the
operating (seawater rejected flowrate and brine recycle flowrate) parameters.
