Computer Methods in Chemical Engineering

While various software packages have become quite useful for performing unit operations and other kinds of processes in chemical engineering, the fundamental theory and methods of calculation must also be understood in order to effectively test the validity of these packages and verify the results. Computer Methods in Chemical Engineering presents the most commonly used simulation software, along with the theory involved. It covers chemical engineering thermodynamics, fluid mechanics, material and energy balances, mass transfer operations, reactor design, and computer applications in chemical engineering. Through this book, students learn: What chemical engineers doThe functions and theoretical background of basic chemical engineering unit operationsHow to simulate chemical processes using software packages How to size chemical process units manually and with software How to fit experimental dataHow to solve linear and nonlinear algebraic equations as well as ordinary differential equations Along with exercises and references, each chapter contains a theoretical description of process units followed by numerous examples that are solved step by step via hand calculations and computer simulation using Hysys/Unisim, PRO/II, Aspen Plus, and SuperPro Designer. Adhering to the Accreditation Board for Engineering and Technology (ABET) criteria, the book gives students the tools needed to solve real problems involving thermodynamics and fluid-phase equilibria, fluid flow, material and energy balances, heat exchangers, reactor design, distillation, absorption, and liquid–liquid extraction.Table of ContentThermodynamics and Fluid-Phase EquilibriaIntroductionBoiling Point CalculationsDew Point CalculationVapor Pressure CorrelationsRelative VolatilityEquations of StatePhysical Properties Fluid Flow in Pipes, Pumps, and CompressorsFlow in PipesFluid Flow in PumpsFluid Flow in Compressors Material and Energy BalanceIntroductionMaterial Balance without ReactionMaterial Balance on Reactive ProcessesEnergy Balance without ReactionEnergy Balance on Reactive Processes Shell and Tube Heat ExchangersIntroductionDesign of Shell and Tube Heat ExchangerBoilers and Condensers Reactor DesignIntroductionPlug Flow ReactorPacked-Bed ReactorsContinuous Stirred Tank Reactor Distillation ColumnIntroductionSeparation of Binary ComponentsMulticomponent DistillationColumn Diameter Gas AbsorptionIntroductionPacked-Bed AbsorberNumber of Theoretical StagesNumber of Theoretical Stages Using Graphical TechniquePacked-Bed Column DiameterPacked-Tower HeightNumber of Theoretical TraysSizing a Plate Tower Absorber Liquid–Liquid ExtractionIntroductionMaterial Balance Process SimulationIntroduction Appendix A: POLYMATH SoftwareAppendix B: E-Z Solve SoftwareAppendix C: MATLAB/SimulinkAppendix D: Nonlinear Regression of Experimental DataAppendix E: Microsoft VisioAppendix F: General Process Modeling and Simulation (gPROMS) Index Problems and References appear at the end of each chapter.Biographical NoteNayef Ghasem is an associate professor of chemical engineering at the United Arab Emirates University.
