Dimensional Consistency
Now that we have addressed units and dimensions and unit conversions, we can immediately make use of this information in a very practical and important application. A basic principle exists…
Conversion of Units
As an engineer you must be able to handle all kinds of units and be able to convert a given set of units to another with ease. As you probably…
Systems of Units
As you will see in this chapter, the proper handling of units is an essential part of being an engineer. Moreover, checking the consistency of units in your equations will…
Future Contributions of Chemical and Bioengineering
The solution of many of the pressing problems of society for the future (e.g., global warming, clean energy, manned missions to Mars) will depend significantly on chemical and bioengineers. In…
Where Do Chemical and Bioengineers Work?
Table 1.1, which lists the percentages of all chemical engineers by employment sector between 1996 and 2007, shows that the percentage of chemical engineers in these developing industries (pharmaceutical, biomedical,…
A Brief History of Chemical Engineering
The chemical engineering profession evolved from the industrial applications of chemistry and separation science (the study of separating components from mixtures), primarily in the refining and chemical industry, which we…
Analysis of binary distillation by Ponchon-Savarit Method
The method is concerned with the graphical analysis of calculating the theoretical stages by enthalpy balance required for desired separation by distillation process (Hines and Maddox, 1984). In this method,…
Analysis of binary distillation in tray towers
McCabeThiele Method McCabe and Thiele (1925) developed a graphical method to determine the theoretical number of stages required to effect the separation of a binary mixture (McCabe and Smith, 1976).…
Multi-stage Continuous distillation-Binary system
A general schematic diagram of a multistage counter-current binary distillation operation is shown in Figure 4.10. The operation consists of a column containing the equivalent N number of theoretical stages…
Continuous distillation columns
In contrast, continuous columns process a continuous feed stream. No interruptions occur unless there is a problem with the column or surrounding process units. They are capable of handling high…
