摘要： The invention relates to a method for producing bisphenol A prills. According to the method, molten bisphenol A is fed into the prilling tower at the top of said prilling tower, via a nozzle plate with a number of nozzles. A gas coolant which is guided in a circuit is led into said prilling tower in a counter-flow. The bisphenol A prill is cooled to approximately room temperature, collected at the foot of the prilling tower and removed. The invention also relates to a device for carrying out the inventive method and to bisphenol A prills produced according to this method.
