Abstract
Seawater desalination is an important method for
producing fresh water, a critical resource in many areas
of the globe. Multi-stage flash distillation (MSF) is a
leading technology within the thermal desalination field.
Mathematical modelling and simulation provides a means to
enhance engineering and operation of complicated
production plants. This paper presents a new method for
one-dimensional modelling and dynamic simulation of
thermal desalination processes. The approach combines the
simultaneous mass, momentum, and energy solution, local
phase equilibrium by Rachford-Rice equation, and rigorous
calculation of the seawater properties as function of
temperature, pressure and salinity. A brine recycling MSF
plant was modelled as a case study, presenting advanced
and unpublished simulated features and transients. The
successful results suggest that the method presented is a
competent approach for dynamic simulation of thermal
desalination processes.
