rührkesselkontaktor

A Rührkesselkontaktor, often translated as stirred tank contactor or agitated vessel contactor, is a piece of equipment used in chemical engineering for mass transfer operations. It typically consists of a vessel equipped with an agitator and designed to facilitate contact between two immiscible phases, usually a liquid and a gas, or two immiscible liquids. The agitator is crucial for creating turbulence and dispersing one phase into the other, thereby increasing the interfacial area and enhancing the rate of mass transfer.

These contactors are employed in various processes such as gas absorption, stripping, liquid-liquid extraction, and chemical reactions where intimate mixing of phases is required. The design of a Rührkesselkontaktor can vary significantly depending on the specific application. Factors like the type of agitator (e.g., propeller, turbine, paddle), the vessel geometry, and the presence of internal components like baffles influence its performance.

The efficiency of a Rührkesselkontaktor is determined by the degree of dispersion achieved, the residence time distribution of the fluids, and the overall interfacial area generated. They are a versatile and widely used piece of equipment in industries like pharmaceuticals, petrochemicals, and environmental engineering due to their ability to handle a range of operating conditions and achieve efficient mass transfer.
