Alkaline Scale Formation in a Multi-Stage Flash Evaporation-Type Desalination Plant

A Hybrid Methodology for Optimization of Multi- Stage Flash-mixer Desalination Systems

−− In this paper, a new strategy involving an evolutionary algorithmic procedure for the optimization of Multiple Stage Flash (MSF-M) Systems is presented. A “detailed model” of an MSF-M System is developed according to rigorous material, momentum and energy balances for each stage. The model of the MSF-M System is represented as a complex NLP, which incorporates a high number of nonlinear cons...

Hybrid Supervisory Control of the Brine Heater for Multi Stage Flash Desalination Plants

Multistage Flash desalination is the most common process large-scale distillation process to produce freshwater from seawater. Its operation is energy intensive and essential for the maintenance of life support in regions with scarcity of water resources. Such plants need an efficient control system in order to be economically viable. Fortunately, the plant can be broken down into subsystems, w...

Various Approaches to Thermodynamic Optimization of a Hybrid Multi-effect Evaporation with Thermal Vapour Compression and Reverse Osmosis Desalination System Integrated to a Gas Turbine Power Plant

This paper investigates the simulation of a hybrid desalination system composed of multi-effect evaporation with thermal vapour compression desalination (METVC) and reverse osmosis (RO) plant. The hybrid desalination system is also integrated with a gas turbine power plant through a heat recovery steam generator (HRSG). First, a comprehensive Thermodynamic model for HRSG, METVC, and RO are deve...

Study and Enhancement of Flash Evaporation Desalination Utilizing the Ocean Thermocline and Discharged heat

This paper reports on the results of experimental investigations of flash evaporation from superheated jet issues vertically upward from a round straight nozzle of 81.3 mm diameter. For the investigated range of jet superheat degree and velocity, it was shown that flash evaporation enhances with initial temperature increase. Due to the increase of jet inertia and subsequently the delay of jet s...
