Agitator geometry is a "Rushton type" (the most common in chemical industry), but many other impeller geometries can be used. Italiano: Rappresentazione di un recipiente agitato incamiciato. L'agitatore visualizzato in figura è del tipo "Rushton" (il più utilizzato nell'ambito dell'industria chimica), ma molti tipi di agitatori possono essere ...
The mechanical agitator is equipped with a motor which drives a mixing and pumping turbine. This turbine draws the two phases from the settlers of the adjacent stages, mixes them, and transfers this emulsion to the associated settler.
An agitator is composed of a drive device ( motor, gear reducer, belts…), a guiding system of the shaft (lantern fitted with bearings), a shaft and impellers . If the operating conditions are under high pressure or high temperature, the agitator must be equipped with a sealing system to keep tightened the inside of the tank when the shaft is ...
Such bearings should be equipped with the shaft position control system, which adjusts the fluid pressure and consumption according to the rotation speed and shaft load. [4] In fluid-dynamic bearings, the bearing rotation sucks the fluid on to the inner surface of the bearing, forming a lubricating wedge under or around the shaft.

A typical batch reactor consists of a pressure vessel with an agitator and integral heating/cooling system. The vessels may vary in size from less than 1 L to more than 15,000 L. They are usually fabricated in steel, stainless steel, glass-lined steel, glass or exotic alloys. Liquids and solids are usually charged via connections in the top ...
Diagram showing the setup of a continuous stirred-tank reactor. The continuous stirred-tank reactor (CSTR), also known as vat-or backmix reactor, mixed flow reactor (MFR), or a continuous-flow stirred-tank reactor (CFSTR), is a common model for a chemical reactor in chemical engineering and environmental engineering. A CSTR often refers to a ...
Diagram showing principle of constant bearing, decreasing range in marine collision avoidance. When an observer sees another vessel at a constant bearing and the range continually decreases, collision is imminent. A ship seen to be on a constant bearing with decreasing range will collide with the observer's ship unless avoiding action is taken.
