The number of types of reactors is very large in the chemical industry. Even for the same operation, different types are used. Chemical reactors can be designed as either tanks or pipes, depending on the needs, and they can vary in size considerably. Small benchtop [1] chemical reactor … Chemical engineers are designing reactors where the fluids to be reacted are oscillated inside a reactor with baffles at frequencies between 0.5 and 15 Hz with amplitudes in the range 1 to 100 mm. This allows for very effective mixing of the reactants and also for heat to be transferred to the surroundings.

 · Most reactors used in industry approximate the ideal batch reactor, PFR, or CSTR. In fact, real reactors can be modeled as networks or combinations of multiple plug-flow and stirred-tank reactors (Towler and Sinnott, 2013). Chemical reactors. The reactors, in which chemicals are made in industry, vary in size from a few cm 3 to the vast structures that are often depicted in photographs of industrial plants. For example, kilns that produce lime from limestone may be over 25 metres high and hold, at …

In chemical engineering, CSTR reactors with well-mixed conditions and liquid level control are very common. Within these ideal CSTR reactors, the perfect composition of the mixture and the outlet is assumed to be the same as that of the material inside the reactor. 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. In flow chemistry , a continuous stirred tank reactor (CSTR) equipped with features to continuously feed and exhaust reactants is an example of a mechanically mixed flow reactor.

Biochemical Reactor. Bioreactors are devices or systems that provide a biologically active environment, where microorganisms and enzymes are immobilized, and biochemical reactions are performed in porous beds, and porous ceramics are often used as such bioreactor beds due to chemical stability of ceramics and accommodative function of porous structure [20].
