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
Abraha Woldai received his PhD from the University of Bath, UK in 1997. From 1985 to 1999, he worked in the Water and Electricity Department, Government of Abu Dhabi, in various areas. From 1989 to 1999, he participated in the development of the modeling, simulation, and validation of data for MSF desalination plants on behalf of the Directorate of Power and Desalination Plants, Water and Electricity Department, Government of Abu Dhabi, and the International Foundation for Water Science and Technology in the field of desalination plant control. In addition, Dr. Woldai has authored/coauthored several research papers on power and desalination.

Die verhaal van die kasarm en die Calitze kom tot 'n mooi einde
Ek kan nie ’n boek summier toemaak nadat die slotsin geskryf is nie. Ek lees álles, tot by die outeursnotas en die bronnelys (gewoonlik gooi ek darem net vlugtig ’n oog oor die bonne!). Chanette Paul maak in die nota oor Maanschijnbaai 2, die verdere verhaal van Nan en Jeannie, die stelling: “Lesers moet my asseblief vergewe dat my verbeelding altyd die oorhand oor die werklikheid kry en verdigsel voorkeur bo feite.” (p.635) Ek wil daarby aanhaak en bieg dat ’n uitstekende verhoudingsroman soos hierdie tydelik die oorhand gekry het oor my traagheid om te lees oor reïnkarnasie en die esoteriese. Die klomp Calitzse het my tyd en aandag totaal gekaap.
Die skrywer wy die laaste bladsye aan ’n verduideliking oor hoe die Maanschijnbaai-tweeluik ontstaan het. Sy beweer dat die Calitze haar “onkant” betrap het. Sy wou ’n romanse skryf maar uiteindelik was die karakters so kompleks dat dit op twee dik boeke en ’n intense familiedrama uitgeloop het.
Van die onderskeie karakters raak diep waarhede kwyt wat die moeite werd is om te onderstreep en te onthou, soos Zach wat dit gehad het oor die risiko om iemand op ’n pedestal te plaas omdat jy daardeur die persoon ’n onreg aandoen. (p.539) En Nan, wat die hele klomp Calitze moes grootkry, se wyse raad: “Met eerlikheid, Jeannie, kom ’n mens baie verder as met opoffering. Met eerlikheid gee jy almal ’n regverdige kans. Opoffering beteken bloot jy doen iets teen jou sin omdat jy glo dit sal ander baat.” (p.613)
Maak seker dat jy genoeg tyd op hande het, dan lees jy hierdie tweeluik in volgorde, Jo & Sue, gevolg deur Nan & Jeannie. Dit is hersien en met splinternuwe, pragtige baadjies uitgegee deur Lapa Uitgewers.
A very practical approach and the tools to go along with it
Very useful. The book provides a structure and an approach that I would have been useful earlier in my investing. I like the five gates and in particular the attention to quality and management's capital allocation decisions. I will also apply the idea of the stewardship log to get more explicit on my investment theses. This is kind of the practical aspect of what I learned from the Psychology of Money.
the title ties in really nicley the more towards the end but the title for the book suits it real...
the book is very slow burn and takes a while for like captivating parts of the book .but the middle to the end the pace of the book is really nice the beginning is just repetitive and and trust the processes
Skuld en vergifnis word nie versuiker in hierdie jeugverhaal nie
Twee halwes maak ’n hele is die wenner van ’n jeugboekprys. Ek moes myself gedurig herinner wat die teikenmark nou eintlik is, want die sake wat aangeraak word, is geensins beperk tot jeugdige lesers nie. Die sterk newe-karakters dra daartoe by die selfs baie ouer lesers goed aanklank kan vind by die storielyn wat ontvou.
“Hulle sê as jy iemand vergewe, lig jy ’n vrag van daardie persoon se skouers af. Maar miskien is sommige dinge net te swaar om van iemand anders se skouers te lig?” (p.178) Baie aandag word gegee aan skuld en vergifnis, maar geen suikeromhulde kitsoplossings word aangebied nie. Dit sou die storie beslis vervlak het.
Na die aardskuddende ontdekking wat Lira gemaak het, gaan sy vir drie maande na ’n Griekse eiland en maak sy kennis met haar ander helfte, ’n halfsuster wat presies die teenoorgestelde is van haar eie ingetoë, overthinking self. Ek het daarvan gehou dat hulle, die verskille ten spyt, nie in heftige konflik was nie. Eerder besig om algaande te ontdek dat hulle by mekaar kan aanpas en albei sterker daardeur kan kom.
Marita van der Vyver is ’n waardige wenner van die Tafelberg Jeugboekprys en hierdie boek hoort beslis in van der Vyver versamelings. Dit is uitgegee deur Tafelberg, ’n druknaam van Jonathan Ball Uitgewers.
