Carbon Fiber Composite Materials Extending Cooperation for Column Internals

Editor: Ahlam Rais

Sulzer Chemtech, one of the market leaders for separation and mixing technology, and SGL Group, a leading worldwide manufacturer of products made from carbon, are expanding their cooperation in the field of column internals based on SGL’s carbon fiber composite materials (CFC) going by the brand name Sigrabond.

Carbon and graphite products are used whenever other materials such as steel, aluminum, copper or plastic fail due to their limited material properties for example, temperature and corrosion resistance. In addition to the CFC structured packing that has already been marketed successfully under the Sulzer brand name Mella Carbon, the existing CFC column internals portfolio – mainly support systems – is now completed with liquid distributors, collectors and feed pipes made of Sigrabond.

According to the company, the new column internals, introduced under the brand name Mella Carbon, are as corrosion-resistant as graphite liquid distributors used to date, but are at the same time lighter, stronger, stiffer, more rigid, more temperature resistant than plastics and have lower cost than special metals. An innovative connection system enables the realization of larger diameters and allows cost efficient production.

In recent months, more than 30 new CFC liquid distributors have been designed, manufactured and successfully commissioned for industrial applications – often with the associated Mella Carbon packings, support grids and feed tubes, adds the firm. This is the first time that a complete family of CFC based column internals has been made available to customers of the cooperation partners worldwide. The often-difficult combination of materials, especially for corrosive applications, is no longer necessary.
