Continuous Stirred-Tank Reactor: Comprehensive Overview

2021-7-1  The continuous stirred-tank reactor is known as CSTR, or commonly the stirred tank reactor (STR), and it is similar to the batch reactor. The main difference is that preparation must be made for continuous flow of ingredients in the reactor by gravity or forced-circulation flow using a pump for the stirred tank reactor.

Fundamentals of Chemical Reactor Theory1

2010-1-14  A Continuous-Stirred Tank Reactor (CSTR) is a well-mixed vessel that operates at steady-state (Qin=Qout=Q). The main assumption in this case is that the concentration of the incoming fluid will become instantaneously equal to the outgoing upon entering the vessel. Fig. 2 explains visually this concept. Fig. 2. Continuous-Stirred Tank Reactor

Continuous Stirred Tank Reactors - University of Michigan

Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.
