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.
