Embodiment Construction
[0012] The process according to the invention can preferably be performed in such a way that the gas bubbles generated in the mixing organ have a maximum diameter of 2.5 mm, particularly preferably of less than 1.5 mm, in order to permit a rapid transfer to the liquid phase.
[0013] Examples of possible mixing organs with which this size of gas bubble can be achieved include perforated plates, diffuser stones, static mixers or nozzles.
[0014] A Venturi nozzle is particularly suitable for the process according to the invention. This known device has a lower pressure drop in comparison to other mixing organs. Depending on the energy supplied and the volumetric flow rate, the nominal width of the channel is set in such a way that the maximum gas bubble diameter does not exceed 2.5 mm.
[0015] The mixing organ is preferably positioned in such a way that the preoxidized substance can pass from the oxidation reactor to the mixing organ by natural circulation. The mixing organ can be fitted dir...
