Reactors / Autoclaves/Agitated/ Vessels


Vessels equipped with Agitator system are called REACTION VESSELS, AGITATOR VESSELS or simply REACTORS. Operations such as Mixing, Blending, Dissolutions, Chemical reactions, at moderate Pressures &Temperatures under controlled conditions are carried out in these equipment..If the Agitator vessel is designed to withstand High Pressures & Temperatures, during the reaction process , it is called AUTOCLAVE. Besides agitation the vessel may require heating and /or cooling of its contents, which is achieved by internal coils, external jacket or limpet coils.The capacities of Reactors are defined in Volumes, viz. M3 ,KL, Gallons etc.

Design & Fabrication

For a Reactor ,design & fabrication of the VESSEL part is carried out as per codes viz.-ASME, IS,BS, AD. Merkblatter or Good Engg. Practice.

AGITATORS & relevant components are designed & selected while keeping in mind the process intended i.e. continuous stirring, liquid - liquid extraction, dissolution etc. & by referring to procedures laid down in Engineering Equipment Users Association (EEAU) handbook.

Agitators / Impellers

Agitator components consists of shaft ,impeller. The impeller is made up of the blades which are attached to the hubs by bolting or welding & these are fitted on to the shaft. Each impeller has its own unique application & characteristics. While selecting the impeller type, due consideration is given to the vessel geometry, impeller geometry and properties of the contents being agitated as its viscosity, density and phases present as also the application intended, whether suspension or dispersion of solid phases, gas dispersion, emulsion of immiscible liquids, blending of miscible liquids or fluid motion for energy transfer.
Correct determination of Shaft diameter/size, Motor ratings, proper selection of Speed reduction/variation equipment, Shaft sealing arrangement, Bearings baffle arrangement etc are some of the important factors that are taken into consideration, while designing an optimum agitator system.
