A Continuous Stirred-Tank Reactor (CSTR) is a chemical reaction vessel in which an impeller continuously stirs the contents ensuring proper mixing of the reagents to achieve a specific output (Figure (PageIndex{1})). Useful in most all chemical processes, it is a cornerstone to the Chemical Engineering toolkit. Proper knowledge of …
The CEM-MKII Continuous stirred tank reactor is probably the most common type of reactor found in industry. The CEM-MKII is a small-scale demonstration version for educational use. It is extremely flexible in use and can be used for both continuous and batch reactions.
An ideal continuous stirred tank electrochemical reactor gives perfect mixing, and the outlet concentration is equal to the concentration inside the reactor. The CSTER can be operated either by galvanostatic or potentiostatic condition and the deviation is mainly due to the process dynamics.

The reactors picked were the Continuous stirred tank reactor and the upstream anaerobic sludge reactor. A tempered steel CSTR of 5 L supreme volume was worked semi-steadily with an HRT of 20 days. The temperature was kept up at 55 °C using self-limiting warming twist collapsed over the reactor divider. The reactor was dealt with 175 …
Continuous-Stirred-Tank Reactor (CSTR) We next examine again the well-stirred reactor. Consider the following step-response experiment: a clear uid with owrate Q f enters a well-stirred reactor of volume V R. At time zero we start adding a small ow of a tracer to the feed stream and measure the tracer concentration in the e uent stream.
