Continuous Stirred Tank Reactors or CSTRs for short, are the most basic continuous reactors used in chemical processes. In this video, Dr Joe Socci, will be giving an overview of CSTRs and how they differ to simpler batch reactors. How does batch reactors work?
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.
Agitation tank uses motor v-belt driving impeller to rotate. regularly mixes the drugs and slurry, increases the role of pharmaceutical drug reactions and enhances the quality reaction time. This machine applies to the mining dressing and also used as a variety of chemical industry trough cake mix. The classic way to agitate plating solutions has been either air agitation or, to a lesser extent, cathode reciprocation. An older paper that is difficult to find, Exploitation of Eductors Agitation in Copper Electroplating, by D.R. Gabe, M. Ward and J.N. Crosby, presented at the June 1999 Sur/Fin, addressed the question of efficient agitation methods. Using a mathematical relationship that we needn’t concern ourselves with here, the following enhancement factors were determined.

Develops high circulation velocities throughout the tank. Reduction in gassed power number much lower as gas flow rate increases. Some of the impellers used in our inhouse pilot plant agitation setup.To carry out the scale up study. Study feasibility. Optimise power consumption.
The agitator tank can suspend solid particles in the solution, accelerate the process of chemical reaction, heat transfer, mass transfer, mix and disperse two or more immiscible liquids to obtain a kind of mulsion, mix two or more immiscible liquids to obtain a homogeneous mixture and achieve gas-solution mixing.
Agitator tank is the necessary equipment that regularly mixes the drugs and slurry, increases pharmaceutical drug reactions. Agitator tank uses motor V-belt driving impeller to rotate. Regularly mixes the drugs and slurry, increases the role of pharmaceutical drug reactions and enhances the quality reaction time. This machine applies to the mining dressing and also used as a variety of chemical industry trough cake mix. Star Trace Specialized in manufacturing, supplying, exporting, and
The first type of device for this purpose is somewhat similar to those for agitating fluids, with an impeller slowly rotating in a tank. The impeller can be a close-fitting anchor agitator as in Fig. 3.4-2b, where the outer sweep assembly may have scraper blades. A gate impeller can also be used which has horizontal and vertical bars that cut the paste at various levels and at the wall, which may have stationary bars. A modified gate mixer is the shear-bar mixer, which contains vertical
The continuous stirred tank reactor in the form of either a single tank or (more often) tanks in series, is used widely and is particularly suitable for liquid phase reactions. It is particularly used in the organic chemicals industry.

CSTRs are very similar to batch reactors in the sense they contain the 4 main components, the vessel, reaction medium, head space and agitation. You can have one CSTR running or several CSTRs connected in series. The reactants are continuously added and products are continuously removed. CSTRs are run at steady state and a uniform composition is assumed throughout each reactor.
A. I agree 100 percent with your chemical vendor that good agitation is important in good quality plating. The classic way to agitate plating solutions has been either air agitation or, to a lesser extent, cathode reciprocation.
Aim of agitation: • Produce a homogeneous mixture • Dissolve solids • Catalyze a chemical reaction • Promote growth of a crystalline product from a supersaturated solution Solid particle suspension regimes Four different regimes apply for solid suspension: 1) Incomplete suspension: all or part of particle rest at the bottom tank, forming “fillets”. This regime may be acceptable only if the amount of unsuspended particles is small; 2) On-bottom suspension: particles are suspended
