    • A process for producing bisphenol-A prills from molten bisphenol A which comprises using a palletizing apparatus comprising: a palletizing tower in which molten bisphenol A is sprayed and brought into contact with a circulating gas to form pellets; a powder removal apparatus in which powdery bisphenol A contained in the circulating gas is removed; a circulating-gas cooler for regulating the temperature of the circulating gas; and a blower for circulating the circulating gas. In the process, the phenol concentration in the circulating gas is regulated to 50 ppm by volume or lower. The process eliminates troubles such as a decrease in heat transfer caused by deposit accumulation in a heat exchanger in the palletizing step and an increase in differential pressure caused by deposit accumulation in the palletizing tower and heat exchanger. Thus, high-quality bisphenol-A prills can be continuously, efficiently, and stably produced for long.
    • 一种从熔融双酚A生产双酚A颗粒的方法,其包括使用码垛装置,其包括:将熔融的双酚A喷射并与循环气体接触以形成颗粒的码垛塔; 除去包含在循环气体中的粉末状双酚A的粉末去除装置; 循环气体冷却器,用于调节循环气体的温度; 以及用于使循环气体循环的鼓风机。 在此过程中,将循环气体中的苯酚浓度调节为50体积%以下。 该方法消除了由于在码垛步骤中的热交换器中的沉积物积聚导致的热传递减少以及堆垛塔和热交换器中的沉积物积聚引起的差压的增加的麻烦。 因此,高品质双酚A颗粒可以连续,高效,稳定地生产。
