Reactors for Biodiesel Production – Farm Energy

The most common continuous-flow system in biodiesel production is the continuous stirred-tank reactor (CSTR). At first glance a CSTR, such as that shown in Figure 1, appears to be identical to a batch reactor. In fact, often the actual reactor may be the same, but additional controls are needed to set the reactor up in a continuous-flow system.

Continuous flow stirred tank reactors

Figure 5.4. The residence time distribution of a CSTR. The relative number of molecules resident within the reactor for a particular time N, is plotted against the normalised residence time (i.e., tF/V, where V is the reactor volume, and F is the flow rate; it is the time relative to that required for one reactor volume to pass through the reactor).

CSTR - Visual Encyclopedia of Chemical Engineering

A CSTR can also function as a loop reactor when a heated, pressurized fluid is injected into the system to facilitate the stirring. This allows for higher heat and mass transfer rates while simplifying maintenance because there is no agitator.
