Difference between batch reactor, CSTR, and PFR - YouTube

WebNov 3, 2015 · Following the fundamentals of chemical reaction engineering , consider how the difference of an ideal plug flow reactor (PFR) and an ideal continuous stirred-tank reactor (CSTR) affects the present polymerization system. Note that a PFR is equivalent to a batch reactor, in which the length in a PFR can be converted to time in a batch reactor. WebIn this way, a higher efficiency may be obtained, or the size and cost of the PFR may be reduced. A PFR has a higher theoretical efficiency than a CSTR of the same volume. …
