The scallop is a fan-shaped component that is mounted on the wall of the radial flow reactor vessel. 

Scallops in the reactor are designed to retain the catalyst and prevent catalyst leakage. The outer surface of the scallop is in contact with the catalyst. They can achieve up to a 10% increase in catalyst volume and increase reforming yield.

Our scallops are installed in a vertical reactor to distribute or collect fluids. They hold the packing and collect and direct the fluid.

We offer various sizes of scallops for the reactor. The scallops are manufactured with the vee wire screen to ensure uniform media distribution and reduce pressure drop.

In the reactor, the scallop is flexible to yield to radial stress and resists buckling or collapse in the presence of axial stress. This makes scallops suitable for various applications, especially the catalytic reforming of hydrocarbons.

Scallops in Reators Design Advantages

1. Improved Filtration Efficiency
The V-shaped design of wedge wire provides precise and consistent filtration. This design ensures that particles larger than the openings are effectively filtered out, preventing clogging and maintaining the smooth operation of the reactor. 
2. Durability and Longevity
The filtration system in the reactor is exposed to high pressure, high temperature, and potentially corrosive substances. Wedge wire scallops can withstand these harsh conditions, reducing frequent maintenance and replacements.
3. Versatility in Design
Scallops in the reactor can be customized to meet specific requirements. The size of the openings, the shape of the scallops, and the overall dimensions of the filter can be tailored to suit different reactor designs and operating conditions.
