WebJun 15, 2024 · In refining chemical and petrochemical applications, conventional scallops are used in radial flow reactors and function as conduits through which gas, vapor or liquids (hereinafter, referred to as “G-V-L”) flow inside the reactor vessel. WebScallops are installed on the inner vessel surface as hollow channels for distributing the gas flow from the walls to the center of the reactor. Each scallop is located adjacent to the next. The flow moves along the scallop axis and is limited by its cross-sectional area. Overall reactor capacity is determined by the sum flow rate of all scallops.
