Abstract: Reducing or preventing foaming in chemical and physical transformation processes in liquid media comprises carrying out the transformation in a buoyancy-free jet reactor with no baffles, which has a tapered lower part and is fitted with a gas injector in a position which facilitates circulation without buoyancy. The reactor contents are thoroughly mixed by gas injection. Also claimed is an apparatus for the above process, with a pipe connection for taking off a high-solids suspension and an inlet tube for a liquid medium above the gas injector, the outlet of this tube being located in the cloud of bubbles formed when the apparatus is working.
