Continuous stirred-tank reactor - Wikipedia

Jul 23, 2005 · The continuous stirred-tank reactor (CSTR), also known as vat-or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering.A CSTR often refers to a model used to estimate the key unit operation variables when using a continuous agitated-tank reactor .

Mass and Energy Balances

The reactor can be any control volume we want it to be. So the term reactor analysis is used to describe the application of the mass balance process to environmental situations also. Reactor analyses can be divided into two types: CSTRs (Continuously Stirred Tank Reactors) and PFRs, or Plug Flow Reactors. We have defined CSTRs already---they .

Mar 10, 2016 · Plug Flow Reactors (PFRs) Another type of reactor used in industrial processes is the plug flow reactor (PFR). Like the CSTRs, a constant flow of reactants and products and exit the reactor. In PFRs, however, the reactor contents are not continuously stirred. Instead, chemical species are flowed along a tube as a plug, as shown in Figure 25.2.

Liquid Phase Reactor: Sucrose Inversion | Protocol

In the absence of an extensive recycle stream, such packed bed reactors are typically modeled as "plug flow". The other most common continuous reactor is a stirred tank, which is assumed to be perfectly mixed. 1 One reason for the prevalence of packed bed reactors is that, unlike most stirred tank designs, a large wall area to reactor volume .

Chapter 5: Immobilised enzymes and their uses

Batch reactors generally consist of a tank containing a stirrer (stirred tank reactor, STR). The tank is normally fitted with fixed baffles that improve the stirring efficiency. A batch reactor is one in which all of the product is removed, as rapidly as is practically possible, after a fixed time.

The RTD of a plug flow reactor is shown in Fig. 2. The other extreme is the RTD of a continuous stirred tank reactor (CSTR) in which all elements within the reactor have equal probability of leaving the reactor in the next dt units of time at any moment. The RTD of a CSTR is an exponential decay function as shown in Fig. 3.
