Nowadays there are many types of chemical reactors in industrial engineering that can be classified according to the mode of operation, the type of internal flow, according to the phases, among others, although in this article we are going to discover the most interesting things to choose a pressure laboratory reactor.
Remember that a chemical reactor is the device where a chemical reaction occurs, the container inside which this phenomenon occurs.
Do you dare to immerse yourself in the world of the pressurized laboratory reactor?

How to choose the type of laboratory reactor?
Advantages of IDI SL pressure laboratory reactors.
Stirred pressure reactors are used for chemical reactions under pressure such as hydrogenations, development of polymers and catalysts in R&D laboratories and for production in Pilot Plants. They can work with interchangeable glass, high-pressure and high-temperature steel vessels of different volumes, while powerful stirring systems with magnetic coupling ensure efficient stirring (high viscosity).
Laboratory reactors are manufactured in different volumes according to the applications: from 10 ml to 5 liters, the most common, but there are also 20 liters and even 500.
These industrial engineering equipment are manufactured in glass or metal, always consisting of two parts: the cylinder where the reaction mixture is introduced and the lid where it contains the different valves, connections, validation instruments and safety elements.
2. What types of pressure laboratory reactor exist in industrial plants?
Glass reactors
As they are transparent, they allow the development of reactions to be observed, which provides very useful information on color changes, state of aggregation … As a disadvantage, they are not susceptible to working at medium or high pressures.
Metallic reactors
It is usually made of AISI 316 stainless steel, but also made of titanium, nickel, zirconium and other alloys. They allow working at higher temperatures and pressures, up to hundreds of atmospheres and about 500 ° C.
Most organic reactions can be carried out in stainless steel, although there are other corrosion resistant alloys for use in reactions with acids, bases, salts or corrosive gases.
Another option is to use an enameled or Teflon glass located inside the metal cylinder to avoid direct contact of the reaction mixture, which requires a special coating for the inside of the lid.
Valves or connections can be incorporated in the reactor lid, which is usually screwed by means of a metal ring with a closing system that ensures tightness, to allow the entry of gases, sampling, measurement of internal parameters or safety elements.
3. How to choose the type of laboratory reactor in industrial engineering?
These are the factors to consider when selecting the type of reactor:
Measurement of the reaction vessel: it is recommended that the charge of the reaction mixture does not exceed two thirds of the free volume of the equipment
Internal working pressure
Working maximum working temperature
Mounting type
Heating system: heating blanket, outer jacket, etc.
Decide whether or not agitation is necessary. In the first case, a mechanical stirrer is usually used.
