Sowgath M., 2017, Minimise the Operation Schedule Time to Meet the Daily Fixed Water Demand of MSF Desalination, Chemical Engineering Transactions, 57, 463-468.
Multi Stage Flash (MSF) desalination process is the largest sector in providing fresh water to the gulf region. The production of fresh water from an MSF process can vary with daily temperature variation of seawater producing more water during the night than during the day whereas the demand during the day is usually more than at night. In this work, a Dynamic Optimisation (DO) problem is formulated and solved within gPROMS based on Control Vector Parameterisation (CVP) where the minimum schedule time problem for fixed water demand is solved to achieve the optimal trajectories. The dynamic seawater temperature profile is considered to be piecewise constant or linear in each time zone.
