Whats better for an exothermic reaction a PFR or CFSTR reactor?

Answer 1

That depends on what kind of reaction system you have. Generally, large CSTRs are not suited for use at high pressures because of mechanical strength limitations. Typically, they are used for liquid phase reaction systems at low or medium pressures when appreciable residence times are required. PFRs are more suitable at higher pressures and temperatures. The PFR are usally employed for liquid phase reactions when relatively short residence times are needed. It is the reactor of choice for continuous gas phase operations. Hope that helps.

Answer 2

For an exothermic reaction, a PFR (Plug Flow Reactor) is typically preferred over a CFSTR (Continuous Stirred Tank Reactor) because it allows for better temperature control. In a PFR, the reactants flow through and react along the length of the reactor, allowing for efficient heat removal or addition at different points. This helps to prevent temperature spikes and maintain better reaction control compared to a CFSTR where the reactants are continuously stirred together, leading to less efficient temperature regulation.
