ABSTRACT:
The invention relates to a method for forming controlled vortexes and for circulating gas thereby in a reactor (1, 15) containing liquid or a suspension of liquid and solids. Into the reactor there is also fed gas, so that the liquid is set into a turbulent motion by means of mixers (4, 17, 18) and flow baffles (6, 17, 19). By means of adjustable flow baffles (6, 19), there are created in the reactor at least two vortexes (10), external to the mixer shaft, for sucking gas from the suspension surface into the liquid phase.
