MACH Super Rings

MACH Super Rings are durable, reliable tower packing options suitable for use in a variety of mass transfer and heat transfer applications. They feature an open design with many contact points. This type of design enables homogenous gas and liquid distribution while preventing entanglement.

We offer our Super Rings in a variety of sizes and in both 304 and 316 stainless steel. Contact MACH Engineering to request a quote or get more information about the benefits and potential applications of our product.

Sizes and Materials

MACH Super Rings range in size from 0.1 inches to 4 inches. Larger rings have a larger void area and smaller geometric surface area.

We manufacture our products in both 304 and 316 stainless steel — both offer durability and long-term performance, even in high-temperature and high-pressure applications. 316 stainless steel has two percent molybdenum content, which delivers improved corrosion resistance, making it suitable for use with sulphuric acid, bromides and other highly caustic chemicals.

Compatible Chemicals and Applications

As a full-service tower packing supplier, MACH Engineering designs and sells a wide range of products for various use cases. Our Super Rings are an excellent choice for:

  • CO2 and H2S removal from natural gas and biogas. When used with amine-based solvents, Super Rings will minimize the hydraulic impact of foaming — a common issue in working with MEA, DEA and other solvents.
  • H2S, CO2 and mercaptan removal as part of natural gas liquid (NGL) treatment. Super Rings help improve NGL purity by promoting uniform droplet dispersal, enabling increased capacity and efficiency in continuous and dispersed phase distributors.
  • Butadiene production. Super Rings’ high specific liquid loads make them a smart choice for main wash, rectifier, degasser and other divided wall columns, where they prevent efficiency loss and improve hydraulic performance.
  • Methane separation and other processes requiring low temperatures and high operating pressures. When separating methane from heavy hydrocarbons, Super Rings will facilitate improved contact between the liquid and gas phases.

Super Rings are one of the newest tower packing media types. A high-performance product, they provide a uniform surface area in any orientation. This configuration maximizes exposure and minimizes dry zones.

In the right application, Super Rings will provide significantly reduced pressure drop as well as improved stability and anti-fouling. This change, in turn, will help you reduce operating costs by running smaller columns with higher capacities, increasing overall efficiency and run times while keeping downtime to a minimum.
