Chemical reactor - Wikipedia

Chemical reactor - Wikipedia

A chemical reactor is an enclosed volume in which a chemical reaction takes place. In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction, which is one of the classic unit operations in chemical process analysis. The design of a chemical reactor deals with multiple aspects of chemical engineering.

In environmental engineering and chemical engineering, the term Continuously Stirred Tank Reactor, or CSTR is used for such a system. An example of a CSTR is shown in Figure 1 . We will use a mass balance for a control volume which encloses the CSTR in Figure 1 as an example to describe the meaning of each term in equation 14 .

For example, if a reactor has a volume of 20 m 3 and the feed rate of reactants is 40 m 3 h-1 the residence time is 20 m 3 /40 m 3 h-1 = 0.5 h. It is simple to control accurately the flow rate of reactants. The volume is fixed and therefore the residence time in the reactor is also well controlled.

Continuous Flow Reactors 3.3. Reactor Sizing Reactor Sizing Given –r A as a function of conversion, -r A = f(X), one can size any type of reactor. We do this by constructing a Levenspiel Plot. Here we plot either F A0 / -r A or 1 / -r A as a function of X. For F A0 / -r A vs. X, the volume of a CSTR and the volume of a PFR can be represented .
