The residence time distribution of a CSTR. The relative number of molecules resident within the reactor for a particular time N, is plotted against the normalised residence time (i.e., tF/V, where V is the reactor volume, and F is the flow rate; it is the time relative to that required for one reactor volume to pass through the reactor).

The continuous stirred-tank reactor (CSTR), also known as vat- or backmix reactor, or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering.

Jan 21, 2018 · PFR is one of the ideal reactors which provides higher conversion. In an ideal PFR, there is no mixing along the axial length although there would be lateral mixing of the reactants along the radial direction.

The CSTR plays a very important role in some electrochemical pro- cesses in which the electrochemical reactor is used Parallel or Competing Reaction The reactions in which a substance reacts or decomposes in more than one way are called parallel or side reactions. If we assume that both of them are first order, we get.

What specifically causes a CSTR in series to have a higher conversion than a CSTR in parallel? The CSTR is always operating a the lowest concentration, the exit concentration. When say two CSTRs are in series, the first operates at a higher concentration, therefore the rate is greater, therefore the conversion is greater. Start studying Series, Parallel and Real Reactors.

Chemical Reaction Engineering - Part 16 - more reactors Richard K. Herz, [email protected], www.ReactorLab.net More reactors So far we have learned about the three basic types of reactors: Batch, PFR, CSTR. Reactors are usually designed based on rate considerations. Two commonly used reactors are the CSTR (continuous stirred tank reactor) and the PFR (plug flow reactor). These reactors provide enough residence time for the reaction to take place with satisfactory conversion. In such Parallel or Competing Reaction The reactions in which a substance reacts or decomposes in more than one way are called parallel or side reactions.
