May 21, 2015 · 1. Abstract This experiment involves a continuous stirred tank reactor (CSTR) in series. The reactor system consists of three agitated, glass reactor vessels in series. The concentration is kept uniform for each reactor and it is observed that there is a change in concentration as fluids move from one reactor to the other reactor.

Continuous reactor - Wikipedia

Continuous reactors (alternatively referred to as flow reactors) carry material as a flowing stream.Reactants are continuously fed into the reactor and emerge as continuous stream of product. Continuous reactors are used for a wide variety of chemical and biological processes within the food, chemical and pharmaceutical industries. A survey of the continuous reactor market will throw up a .
