Since 2014, Orion has conducted in-depth analyses of the SNOX™ process, including investigative site visits to existing Topsoe plants and testing the concept at one of Orion’s manufacturing facilities.
In particular, Orion was convinced by the second-to-none sustainability profile of SNOX, which does not consume any reagents, apart from ammonia for the NOx reduction, and does not consume any water. Other factors that played a major role in their selection were the highest available energy efficiency and the very low emissions level that meets the stringent environmental regulations.
The agreement with Orion includes engineering, licence, proprietary equipment, spare parts, catalyst, and future supervision tasks during commissioning and start-up, as well as service obligations during commercial operation. The SNOX plant is scheduled to be in full commercial operation by April 2021.
The SNOX process removes sulphur dioxide, nitrogen oxides, and particulates from flue gases. The sulphur is recovered as sellable sulphuric acid and the nitrogen oxides are reduced to harmless free nitrogen. The process is based on catalytic reactions and does not consume water, or absorbents. Neither does it produce any waste.
The heat generated in the process can be reused to preheat air in Orion’s process which improves overall efficiency and economics considerably.
Orion is a worldwide supplier of carbon black. Orion produces a broad range of carbon blacks that include high-performance specialty gas blacks, furnace blacks, lamp blacks, thermal blacks and other carbon blacks that tint, colourise and enhance the performance of polymers, plastics, paints and coatings, inks and toners, textile fibres, adhesives and sealants, tires, and mechanical rubber goods such as automotive belts and hoses. Carbon black is produced by the incomplete combustion of heavy petroleum products.
