IDES Worldwide

To illustrate the various gas-liquid contactor designs, consider worldwide phenol production which totaled 6.1 million tonnes in 2001.Bubble columns are the gas-liquid contactor typically used in a common phenol process that oxidizes cumene (at 7 bar and 110°C) to produce intermediate cumenehydroperox-ide. The compressed air introduced into the base of the oxidizer provides oxygen for chemical reaction, as well as the agitation needed to keep the alkali and organic phases intimately mixed.
