Sulzer Chemtech and SGL Group extend cooperation over column internals

Sulzer Chemtech and SGL Group are expanding their cooperation in the field of column internals based on SGL’s carbon fibre 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 such as temperature and corrosion resistance. In addition to the CFC structured packing that has already been marketed successfully under the Sulzer brand name MellaCarbonTM, the existing CFC column internals portfolio – mainly support systems – is now completed with liquid distributors, collectors and feed pipes made of SIGRABOND®.

“The new column internals, introduced under the brand name MellaCarbon, are as corrosion-resistant as graphite liquid distributors used to date, but are at the same time lighter, stronger, stiffer, more rigid and more temperature resistant than plastics and have lower cost than special metals. An innovative connection system enables the realisation of larger diameters and allows cost efficient production," explained Ralph Spuller, SGL Project Manager for the cooperation project.

Over 30 new CFC liquid distributors have been recently designed, manufactured and successfully commissioned for industrial applications – often with the associated MellaCarbon packings, support grids and feed tubes.

Achema 2018 visitors will have the opportunity to see the new internal column exhibit on both companies’ booths: Sulzer hall 4.0, stand D48 and SGL hall 4.0, stand F26.
