Explore a Viable Resource for DesalinationThe world’s freshwater supplies are rapidly depleting and seawater is being positioned as a major feasible replacement in the search for a sustainable water source. Focused on large-scale multi-stage flash (MSF) seawater desalination plants, and based on research conducted on a real 18-stage plant, Multi-Stage Flash Desalination: Modeling, Simulation and Adaptive Control outlines the principles and processes of MSF desalination and highlights the state of the art in MSF desalination modeling, simulation, and control. This book offers a brief overview of MSF plants, explains the importance of the various control systems for large MSF plants, and describes methods of mathematical modeling centered on physical phenomena in the MSF process. It introduces a developed dynamic model and illustrates the simulation of the model using an equation-based flowsheet simulation package (SPEEDUP) from AspenTech. It also presents a method for finding and using a non-parametric model in designing optimal PID control systems and recommends an adaptive scheme that maintains optimal plant operation over a range of operating conditions. The improvements suggested by the author for PID controllers are pervasive in desalination plants of high dimension and also relate to other process industries with comparable conditions. He also discusses the use of renewable energy sources for desalination and stresses the potential of solar energy in the Arab region, an area known for its aridity and scarcity of water.The text: Details the dynamic model of the various elements in an MSF plantConsiders the obtained model as well as available measurement dataPresents a developed model for use in PID controlProvides descriptions, listings, and additional reference material for further research Multi-Stage Flash Desalination: Modeling, Simulation and Adaptive Control covers the processes of desalination and the operation and control of MSF plants for large-scale desalination and provides you with a greater understanding of dynamics, operation, and control.

"I am aware of several books available in the field of desalination. This is the only one that exclusively deals with state of the art modeling of multistage flash system and improved PID controls. As a high end text book it will serve both advanced courses and practicing engineers in the field of desalination."—Samir Damak, Consultant in Corrosion"The book summarizes almost one half century of technology and development of one of the prominent desalination technologies. It will be of a major benefit to the reader to understand the technical aspects related to the process design of MSF technology and key role instrumentation and controlling is having on the process. Dr. Abraha Woldai ‘s book is a valuable contribution to the desalination industry and to all who want a better understanding of the important challenges facing the design of MSF desalination technologies."—Corrado Sommariva, ILF Consulting Engineers"The author is to be congratulated … the book is interesting to read and useful in general to academicians but more so to plant operating control engineers dealing with Desalination processes and plants."—Dr. L.Sivakumar, Formerly: General Manager, Corporate R&D, Bharat Heavy Electrical Limited, Presently: Vice Principal & Dean of Electrical Sciences, Sri Krishna College of Engineering & Technology, Kuniamuthur "The book is quite useful for the graduate students interesting in knowing the field for further research and other scientists and engineers working in academia, industry, national labs and MSF plants. The book is a welcome addition to those in the field."—D. Subbaram Naidu, University of Minnesota Duluth, USA
