While continuous reactors are rarely used in the laboratory, a water-softener can beregarded as an example of a continuous process. Hard water from the mains is passed through a tube containing an ion-exchange resin. Reaction occurs down the tube and soft water pours out at the exit. Figure 3 Illustrating a continuous reactor.

Summary. Bioreactors are used to grow organisms in large volumes, thereby enabling the production of mass quantities of the target product. These reactors can be batch reactors, which contain all of the components needed for cell growth, or continuous reactors, which have inlet and outlet ports allowing for the addition of fresh growth media and the removal of cell waste.

Tubular reactors are used in a continuous flow mode with reagents flowing in and products being removed. They can be the simplest of all reactor designs. Tubular reactors are often referred to by a variety of names: Pipe reactors Packed-bed reactors Fixed-bed reactors Trickle-bed reactors Bubble-column reactors Ebullating-bed reactors Single-phase flow in a tubular reactor [.]

Continuous Flow Reactors 3.3. Reactor Sizing Reactor Sizing Given –r A as a function of conversion, -r A = f(X), one can size any type of reactor. We do this by constructing a Levenspiel Plot. Here we plot either F A0 / -r A or 1 / -r A as a function of X. For F A0 / -r A vs. X, the volume of a CSTR and the volume of a PFR can be represented .
Jan 05, 2015 · Continuous Reactors • CSTR • Plug Flow Reactor • Tubular flow reactor 26. CSTR • A continuous stirred tank reactor (CSTR) is a vessel to which reactants are added and products removed while the contents within the vessel are vigorously stirred using internal agitation or by internally (or externally) recycling the contents.
A semi-continuous reactor is a reactor for a multiphase reaction in which one phase flows continuously through a vessel containing a batch of another phase. The operation is thus unsteady-state with respect to the batch phase, and may be steady-state or unsteady-state with respect to the flowing phase, as in a fixed-bed catalytic reactor or a fixed bed gas-solid reactor respectively.
A second continuous large scale reactor example was used by Gondrexon et al. for the degradation of an aqueous solution of pentachlorophenol. This reactor was designed as a three stage distillation column with a 500 kHz transducer attached below each stage.

A continuous stirred tank reactor (CSTR) is a batch reactor equipped with an impeller or other mixing device to provide efficient mixing. In chemical engineering the name CSTR is often used to refer to an idealised agitated tank reactor used to model operation variables required to attain a specified output.
A Continuous-Stirred Tank Reactor (CSTR) is a well-mixed vessel that operates at steady-state (Qin=Qout=Q). The main assumption in this case is that the concentration of the incoming fluid will become instantaneously equal to the outgoing upon entering the vessel. Fig. 2 .
Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.
