Continuous flow stirred tank reactors
Definition and meaning of Continuous flow stirred tank reactors in chemistry.
Continuous flow stirred tank reactors are large-scale industrial processing vessels where chemical reactants are continuously pumped in while the resulting newly formed products are simultaneously removed.
In more detail
These robust reactors feature a powerful internal impeller or mechanical agitator that constantly mixes the liquid contents to rigorously maintain a perfectly uniform chemical composition and steady temperature throughout the entire vessel volume. Also widely known simply as backmix reactors, they are highly favored in massive industrial chemical processing facilities for handling complex liquid-phase reactions. The continuous vigorous mixing ensures that the exact concentration of reagents anywhere inside the reactor is perfectly identical to the concentration found in the output exit stream. Because they safely operate dynamically at a continuous steady state, they are ideal for maintaining consistent product quality and preventing dangerous thermal runaways.
