A Chemical Reactor is a process vessel used to carry out a chemical reaction. The reactors vary in sizes. The design of the reactor depends upon the thermodynamics and kinetics of the chemical reactions. Types of Reactors. Most Basic types of chemical reactors are tanks and pipes or tubes. These can be either Batch or Continuous Reactors.

Project work: Modelling of chemical batch reactor

In Chemical engineering, chemical reactors are the vessels designed to contain chemical reactions. Vessels which are widely used in the process industries are generally called batch reactors. A typical batch reactor consists of a tank with an agitator and a heating or cooling system. They may also contain static ba es depending on the application.

Consider the reversible gas phase elementary reaction. The rate law for this gas phase reaction will follow an elementary rate law. Where K c is the concentration equilibrium constant. We know from Le Chaltlier's Law that if the reaction is exothermic, K c will decrease as the temperature is increased and the reaction will be shifted back to the left. If the reaction is endothermic and the .

Especially in stirred reactors, multi-step synthesis is often performed at different temperature levels. In the fine and specialty chemistry sector, low-temperature process conditions down to and below -100°C are not unusual. For the generation of very low temperatures (below -40°C), cryogenic nitrogen is often the cooling medium of choice.

During the past decennia, the stirred tank reactor, especially for gas−liquid operations, has received much attention. However, proper design of turbine-stirred gas−liquid reactors on an industrial scale can still be difficult to make. On the large scale, the removal of heat may become a limiting factor. Installation of additional cooling coils into the reactor vessel makes the design .

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.
