NeXRing - High Performance Packing for Demanding Applications

The development process of Sulzer’s NeXRing is presented using the example of two common ring sizes. It includes well-known methods such as absorption and distillation tests but also new methods like simulations of randomly bulked ring beds based on discrete element method (DEM) and mechanical strength tests in a column with industrial relevant diameter. Comparisons with standard 3rd generation rings demonstrate a significant performance improvement of the new 4th generation ring family.
