also combine a CSTR and a PFR at all series but not in the slowest throughput (Deborah and Penry, 1987). Approximating the gut as a series of CSTRS has been suggested in the context of guts (Penry and Jumas, 1987; Hume, 1989), based on the frequently used (tanks-in series) in approximation with reactor engineering (Fogler, 1999).
Continuous stirred-tank reactors are most commonly used in industrial processing, primarily in homogeneous liquid-phase flow reactions, where constant agitation is required. They may be used by themselves, in series, or in a battery.
A continuous stirred tank reactor (CSTR) is a reaction vessel in which reagents, reactants, and solvents flow into the reactor while the products of the reaction concurrently exit the vessel. ...
