A Practical Approach To Chemical Engineering Fo...
A Practical Approach to Chemical Engineering for Non-Chemical Engineers is aimed at people who are dealing with chemical engineers or those who are involved in chemical processing plants. The book demystifies complicated chemical engineering concepts through daily life examples and analogies. It contains many illustrations and tables that facilitate quick and in-depth understanding of the concepts handled in the book. By studying this book, practicing engineers (non-chemical), professionals, technicians and other skilled workers will gain a deeper understanding of what chemical engineers say and ask for.
This book gives you a wealth of information about chemical engineering. This book is mainly written for individuals who are not studying chemical engineering in universities but for some reason need to have some knowledge about it. The information contained herein could also be beneficial for young chemical engineers. I will try to give you information about chemical engineering not only at the elementary level, but also at a very high level and using very down-to-Earth language. Experienced chemical engineers because this book uses a specific angle of view to chemical engineering, which is different than the angle of view used by universities and colleges.
Chemical engineering is about materials, systems, and their relationships. Materials are something chemists also know about, but with a deeper approach. Systems here means equipment, control systems, and utilities. In this book, we will talk about both of these items.
The heart of chemical engineering is making the conversion of materials happen. There are two types of conversion: physical conversion and chemical conversion. Fig. 1 shows one example of a physical change in a kitchen (left-hand picture) and another of a chemical change in a kitchen (right-hand picture).
If we take several steps toward reality and toward practical concepts (going to the right), then we can see the topics about the fundamentals of equipment. There are two types of equipment or units available in chemical engineering: units for physical conversions and units for chemical conversions. The topic in chemical engineering programs in universities that deals with the fundamentals of units for physical changes is called Unit Operations.
Reactor Design is the topic that deals with the fundamentals of units for chemical conversion. In chemical engineering, each container in which a chemical conversion or chemical reaction occurs is called a reactor.
There is one (and possibly only one) topic in undergraduate chemical engineering programs on the control of process plants, and the name of this topic is Process Dynamics and Control. The reason we need this topic is because we live in a world full of changes (the only constant thing in this world is change), so we need control. Process plants are no different than other things in this world; they need control too.
One other topic that is not in the table is Fluid mechanics; this is one of the fundamental topics in chemical engineering. Why is it fundamental? A process plant could be thought of as a string of conversion boxes, with the fluid passing through them, from one box to the next. This material transfer is done using an understanding of fluid mechanics.
Chemical engineering was born based on the need in process plants. In the olden days, there were engineers (mainly mechanical engineers) who worked in process plants. After a while, people realized that those engineers needed some specific knowledge about the chemical processes, thus was born chemical engineering.
In the rest of this chapter, we introduce each of the above pieces of equipment. We will do it by introducing features of each of them. In the chemical engineering world we name these features as their specifications or, in brief, specs. Understanding these specs are very important when buying the equipment and making sure we are bu
