Metal Random and Structured Packing

Metal Random and Structured Packing

Metal column packings tend to be used in processes that involve higher temperatures, such as distillation. Column packings made out of metal can provide much better temperature resistance than plastic packings.

Pictured below are several popular metal random packings that Raschig USA offers. Each image links to a handout with more information.

Metal Random Packings

The Raschig Super Ring(R) Plus - Superior Packing

The Raschig Super Ring® Plus

The Raschig Super Ring®, refined. This 5th generation column packing promotes further performance increases over its older sibling. This helps to further reduce the size of a planned column, or increase the capacity of an existing column. Whether it is decreasing costs (Smaller column/pressure drop) or increasing bottom line (Increased production), this ring can help.

The Raschig Super Ring(R)

The Raschig Super Ring®

The 4th generation in random packing design. It offers significantly lower pressure drop and equal or superior mass transfer properties vs. traditionally designed random dump metal tower packings.

Metal Pall Rings

Pall Rings (Jaeger Rings, Ballast Rings, Basic Rings, etc.)

Traditional packing for multiple applications.

Raschig Ring

Raschig Rings

The original column packing invented by Dr. Raschig. There are more optimized packings available today, but it’s a classic.

Metal Structured Packings

Structured metal packings are available too. Structured packings tend to offer lower pressure drop and increased capacity when compared to random packings discussed above. Structured packings must be designed and constructed to specific columns.

Raschig Super-Pak(R)

Raschig Super-Pak®

The Raschig Super-Pak® is designed to allow free flow of vapor – liquid streams. Unlike previous structured packing design, there are no sharp directional flow changes within the Raschig Super-Pak® element. Rows of sinusoidal waves within the vertical packing sheets are surface-enhanced to encourage greater turbulent radial spread of thin liquid film flows on the front and back of the waves on each sheet within a packing element. The open structure of Raschig Super-Pak® achieves excellent hydraulic and mass transfer efficiency characteristics. Loading capacity is high, with improved separation, yet pressure drop remains low during normal operation.
