What Types of Orifice Plate Structured Packing Are There

Orifice plate structured packing is a critical tower internal in separation processes, offering efficient mass transfer and good fluid distribution. To choose the right one, understanding its main types is essential.

First, the standard orifice plate packing features uniform, regularly arranged circular or rectangular holes. With a simple structure and low cost, it suits general separation tasks like distillation and absorption in clean fluids. Its stable performance makes it a common choice for routine industrial applications.

Next, high-efficiency orifice packing optimizes hole size, spacing, and arrangement. By increasing specific surface area and reducing flow resistance, it enhances mass transfer efficiency, ideal for precision separation where high purity is required, such as in fine chemical and pharmaceutical production.

Anti-clogging orifice plate packing addresses challenges in dirty or viscous services. It adopts larger holes, open flow paths, and anti-blockage designs to prevent fouling, widely used in industries handling fluids with suspended solids or high viscosity, like wastewater treatment and petroleum refining.

Material also varies: metal (e.g., stainless steel) for high-temperature/high-pressure environments, and plastic (e.g., PP, PVDF) for corrosion resistance. Selecting the type depends on separation requirements, fluid properties, and operational conditions to maximize tower internal efficiency.
