The book aims to provide principles of chemical engineering design and at the same time examples of their application using the most often employed simulation software. The book is divided into four sections: Introduction to design and simulation; Design and simulation of simple unit operations; Plant design and simulation – conventional components; and Plant design and simulation – nonconventional components.
The first section describes basic methodologies for computer aided design followed by a description of basic steps of process simulation in Aspen Plus and Aspen Hysys. Process concept syntheses, data collection, thermodynamic phase equilibrium, physical properties, conventional and nonconventional components, and chemical reaction data are the main topics of this section. The second section is devoted to the design and simulation of individual simple unit operations. After representing a mathematical model of each unit operation such as reactors, separators, heat exchangers etc., examples of real problems are solved using Aspen Plus and Aspen Hysys respectively. Specific requirements for the model of a given type of equipment, if highlighted, and method of its selection and costing are shown.
The third section describes the design of new plants and simulation of existing plants where conventional chemicals and material mixtures with measurable compositions are used. In this section, material integration, energy analysis and economic evaluation are described and shown on examples in Aspen Plus and Aspen Hysys respectively. Specific tools of Aspen Plus and Aspen Hysys for energy and economic analysis of processes are also applied to real examples. The final section covers plant design and simulation of processes using nonconventional components. In many industrial processes, exact composition of material streams is not known. Design and simulation of such processes requires specific approaches. Petroleum refining and upgrading of crude oil distillation products, combustion, gasification, pyrolysis and drying of different solids, and many other processes belong to this group.
