Continuous stirred-tank reactor - Wikipedia

The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering.A CSTR often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output.

takes place in a continuous stirred-tank reactor (CSTR) with a cooling jacket. The reactor runs at steady state when the cooling fails at six minutes. After a few minutes, the chemical engineer notices that the reactor temperature is increasing because of the cooling failure.

Digital Control of a Continuous Stirred Tank Reactor

We project a novel digital control law for continuous stirred tank reactors, based on sampled measures of temperatures and reactant concentration, as it happens in practice. The methodology of relative degree preservation under sampling is used. It is proved that a suitably approximated sampled system, obtained by Taylor series expansion and truncation, in closed loop with the projected .
