Mass Transfer

With the effective radial mixing, the gas-liquid mass transfer coefficient can be enhanced by up to six times as much as would be possible using conventional mixing.

In an Oscillatory Baffled Reactor (OBR) Column, the residence time of the gas phase in the liquid is considerably increased as the mixing properties enhance gas hold up. Additionally bubbles sizes are reduced and more uniform, hence increasing the interfacial area between two phases. Mass transfer improves accordingly.

Similarly in Liquid-Liquid systems, droplet sizes can easily be controlled to deliver increased interfacial area.

In this example, the desired concentration levels can be achieved with an OBR in less than half the time of the traditional process.
