There is a tank for reaction in the Reactor in which an agitator is installed. In this reactor which does the work of Mixing the feed, the composition and temperature are the same at any point. These are of the following types.

i). Mixing Reactor

A mixing reactor is a vessel used to efficiently combine and mix various materials in chemical engineering and other industries. These materials may be liquids, gases, solids, or any combination, depending on the specific application. The reactor provides an environment where materials are thoroughly mixed, promoting desired chemical reactions, physical changes, or simply ensuring a homogeneous mixture.

Characteristics of Mixing Reactors

1. Design

They come in a variety of shapes and sizes, from small laboratory-scale to large industrial tanks. The design depends on the specific mixing requirements, including the properties of the materials to be mixed, the desired mixing intensity and reaction requirements.

2. Agitation

Most mixing Reactors use some form of stirring to create agitation and promote interactions between ingredients. This can be achieved through various agitators, such as propellers, paddles, turbines, or even static mixers.

3. Control parameters

To optimize mixing, various parameters are controlled, such as agitation speed, temperature, pressure and flow rate. Monitoring these parameters ensures efficient mixing.

ii). Back Mixing or Constant 

While CSTR represents ideal perfect mixing, real reactors exhibit varying degrees of back mixing. The level of backmixing in a CSTR can be determined using the Peclet number, which compares the flow rate to the mixing rate.

Many real reactors, such as tubular or packed bed reactors, have some degree of backmixing due to eddy diffusion or flow channeling. Understanding and accounting for backmixing is important for accurate modeling and prediction of the performance of these reactors.

Trbulur Reactor 

This type of reactor is also called plug flow reactor, in this type of reactor the flow of fluid is orderly. In which no element of fluid mixes the element ahead or behind it. In this type of reactor the temperature and composition are different at all points.
