Raschig Rings - Wisconsin Stamping and Manufacturing

Quality and consistency. The key to optimal performance.

Raschig rings are tubular pieces commonly used as random packing materials in chemical processing and mass transfer operations, such as fractional distillation. They are a cylindrical tube typically having an equal length and diameter and may be made from carbon, ceramic, plastic or metal. Due to their critical role in chemical separation processes, it is essential to employ quality and consistent Raschig rings made by an experienced manufacturer.

At Wisconsin Stamping & Manufacturing, we are a full-service manufacturer capable of producing high-quality Raschig rings in a range of sizes and metals. Equipped with over 60 years of experience and made in the USA in our state of the art ISO 9001 certified facility, our team has the skills, knowledge, and tools necessary to produce components tailored to our customer’s exact needs. Our commitment to superior customer service ensures that the customer remains involved throughout the process to provide input and feedback.

Overview of Raschig Rings

Companies employ Raschig rings in a wide variety of tasks that require Chemical Separation, Mass Transfer, or Fractional Distillation. Their surface area and shape creates a randomly packed distillation environment that performs better than fractal patterns and allows for good internal liquid distribution, consistent and repeatable efficiency, and offers a high percentage of void space. Depending on the construction material and wall thickness, they also allow for predictable rates of heat transfer for standardized chemical processes.

Common Applications of Raschig Rings

While Raschig rings can be used for a variety of processes, the components need to be specially formulated to best suit the task, the environment, and the chemicals involved. Some of its common applications include:

● Distilled Spirits manufacturing
● Chemical tower operations
● Ethanol production
● Gas processing
● Absorbers/Strippers
● Pollution control scrubbers
● Mass transfer
● Heat transfer
● Liquid extraction

Benefits of Raschig Rings

Raschig rings—especially metal Raschig rings—offer many benefits, such as:

● Low cost. They can be made from a variety of materials, they are easily tailored to applications at low production costs. Purchasing in bulk, as is common, further reduces the investment required.

● Excellent durability. Raschig rings have long service lives due to their superior resistance to caustic chemicals, acids, and solvents. Their high strength design also reduces fouling and stagnation. Additionally, they resist damage from extreme temperatures and physical shock.

● High capacity and separation efficiency. Metal Raschig rings have the additional benefits of high capacity and separation efficiency.
