AirProtekt removes NOx and HCN contaminants at Scottish carbon fibre plant
AirProtekt has installed and commissioned a combined Regenerative Thermal Oxidation (RTO) system and a Selective Catalytic Reduction (SCR) system to remove oxides of nitrogen and other gaseous contaminants, such as hydrogen cyanide (HCN), from SGL carbon Fibers’ manufacturing facility in Muir of Ord, in the north of Scotland. SGL Carbon Fibers is a subsidiary of German based SGL Group and the Scottish manufacturing site produces carbon fibre for use in a variety of engineering applications.
As part of a major multi million pound investment SGL Carbon Fibers has upgraded the production capacity of its Scottish carbon fibre manufacturing facility with the addition of two new production lines. To assist in handling the additional emissions, including fugitives from the upgraded facility, AirProtekt was selected to supply a third Regenerative Thermal Oxidation (RTO) system at the site in combination with a new Selective Catalytic Reduction (SCR) system. The principal purpose of the new combined system is to treat and remove pollutants such as oxides of nitrogen and hydrogen cyanide.
The chemical reactions during the heating process generate exhaust gases of oxides of nitrogen, hydrogen cyanide, ammonia, carbon dioxide, carbon monoxide and volatile organic compounds (VOCs). The exhaust gases are extracted using Regenerative Thermal Oxidation (RTO) systems that reduce the levels of the contaminants prior to discharge through stacks, which are the main point sources of emissions from the carbon fibre manufacturing process. The new, combined RTO and SCR system was developed, engineered and installed by AirProtekt and Lufttechnik Bayreuth (LTB) to free capacity on one of the older RTO systems, improving the capture of fugitive gases from one of the manufacturing units, and helping to address overall control of the release of odorous emissions from the Muir of Ord facility.
