The Continuous Stirred-Tank Reactor

CSTR model is used to estimate the key unit operation variables when using a continuous agitated-tank reactor to reach a specified output. The mathematical model works for all fluids: liquids, gases, and slurries. Operating a stirred-tank reactor with continuous-flow reactants and products (CSTR) has some advantages over batch operation.

The reactor can operate 24 hours a day for weeks at a times. The CSTR is an easily constructed, versatile and cheap reactor, which allows simple catalyst charging and replacement.  Its well-mixed nature permits straightforward control over the temperature and pH of the reaction and the supply or removal of gases (Harriott, 2003).

By using a continuous agitated-tank reactor in or der to obatain a particular output, the Continuous Stirred-Tank Reactor (CSTR) model is used to measure the key unit operation variables. The mathematical model works for all fluids: liquids, gases, and slurries. Morevoer, operating a stirred-tank reactor with continuous-flow reactants and products (CSTR) carries some advantages over batch operation. It is to be noted that the reactor can continuously operate for the full span of 24 hours a day for weeks without stopping.

The CSTR is an easily constructed, all-purpose, and cheap reactor. The CSTR allows simple catalyst charging and replacement. Its well-mixed nature allows uncomplicated control of the reaction and the provision or elimination of gases over the temperature and pH (Harriott, 2003).
