1. Agitation of gas-liquid systems

1.1 Issues

Gas-liquid systems cover a wide range of industrial applications where material transfer or chemical reaction between phases is required. The efficiency of the operation is closely linked to the exchange area created at the interface between phases.

The stirred tank is often chosen to perform an operation requiring contact between a gas and a liquid, although it is not a simple technology, like the bubble column for example. However, the choice of a stirred tank is a response to certain process requirements or difficulties linked to the physico-chemical properties of the phases. For example, a stirred tank may be chosen when the gas-liquid system is highly coalescent, when transfer performance needs to be high, when the solubility of a species to...
