The concept of the new agitated reactor by Ekato is intended for multiphase reactions with liquid, gases and solids.

Chemical reactions need activation energy. Catalysts reduce this energetic barrier, but the catalyst is often toxic and pyrophoric. Light is an alternative source.

The new agitated reactor combines high productivity and flexibility with a reliable operation of the submerged light sources — mercury or Led lamps submerged into the reaction mass inside a quartz glass tube — states the firm. The glass tubes pass through nozzles in the tank head, where they connect to the power supply and the cooling medium. They need a hermetic sealing and monitoring to ensure that the unexpected case of a glass breakage is immediately detected. Their support must avoid local stress, allow for thermal expansion and prevent from vibration. According to the company, as the power of the UV-lamps ranges from five to 60 KW each, the lamps need to be cooled inside the quartz tubes. Achema: Hall 5.0, Stand D42
