"Raschig Super-Ring®" which sets new performance standards in the use of mass transfer columns. The Raschig Super-Ring® optimized fluid-dynamic design produces an effective mass transfer between the phases flowing in the column. It achieves large interfaces and an even distribution of the liquids over the column cross-section. High loading capacities permit large column throughputs, and low pressure drops yield low operating costs.
Features
- Liquid film flow with entangled packing, similar to our latest model SPIRAX, resulting in large material transfer (Same effect is confirmed with our product, TELLERETTE.)
- Flooding at joints prevented with “Semi Structured Packing”
- Support rings do not have to be completely removed when remodeling shelf block towers
- However, when remodeling to standard packings, support rings need to be completely removed up to the outer-circumference edge.
- Reduced number of redistributors with homogeneous liquid distribution
- Cost savings with high-speed machines
- RSR is available in SUS as well as materials that are thick or thin such as titan, nickel, and tantalum
- HETP, pressure loss and intensity are far beyond the most efficient random packings
- Verified high performance of RSR by tests in the world-class distillation research institute, FRI (Fractionation Research, Inc.)
Major Applications
- Absorption, diffusion and distillation towers
