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.
