The agitated photo reactor by Ekato was designed for multiphase reactions with liquids, gases and solids. The reactor is available in sizes up to 50 m3 and beyond. As light sources, mercury lamps or LED are positioned inside a quartz glass tube. Between four and 20 tubes are submerged into the reaction mass, passed through nozzles in the tank head, where they connect to the power supply and the cooling medium. Cooling is necessary to prevent high surface temperatures of the tubes, which might damage the product. The agitator has to provide high pumping rates and thereby a permanent renewal of the reactants in the irradiation zone. For reactions with gases, bubbles are efficiently dispersed to ensure high conversion rates. With suspensions, agitation facilitates heat removal during reaction. Sealing of the agitator shaft towards the atmosphere is obtained by double or triple acting mechanical seals or by using hermetic magnetic drives.
