Abstract: The S Zorb unit of North China Petrochemical Company was completed and put into operation in 2013. The operation was normal at the early stage. During the process of mixing gasoline in the tank area after major overhaul of the device in 2014, there were serious scale buildup in the reaction product and the raw material heat exchanger and the heat transfer effect was reduced greatly. In order to ensure normal production, post-removal cleaning was required and there was greater safety risk. Through exchanges with device managers of other enterprise and in-depth exchanges with anti-coke scale blockers manufacturers, anti-coke scale blockers began to be added in August 2016, and the effects were obvious. On the one hand, it reduced the scale buildup in heat exchanger, ensured the heat transfer effect of heat exchanger and reduced energy consumption of the device. On the other hand, it also lessened the safety risk caused by cleaning after excision.

Key words: S Zorb unit, scale inhibitor, effect analysis
