The molar feed of component A to the system is 1 mol/s and the concentration of A in the feed is 1 mol/l. The basic design equations, rate laws, thermodynamic and stoichiometric relationships derived also still valid for the design of nonisothermal rectors. The major difference lies in the method of evaluating the design equation when temperature varies along the length of a PFR or when heat is removed from a CSTR.

It is done in a fluidized bed, which can be thought of as a CSTR.

### In contrast, complete mixing in a CSTR reactor produces the tracer concentration throughout the reactor to be the same as the effluent concentration. In other words, in an ideal CSTR, at any travel time, the concentration down the reactor is identical to the composition within the CSTR (Hoboken et al., 2005).

22 Feb 2016 This equation can be integrated along the length of the reactor to yield In a CSTR, shown in Figure 1, there is no spatial variation- the entire which is easy to visualize if the volumetric flow rate is a constant. This is also called as mean residence time. Mass balance – Development of Design Equation. d) What are the concentrations of products C (desired) and D (undesired) in the output stream of the CSTR?
