Topsoe and Orion ink deal

Published by

Haldor Topsoe A/S has announced that its SNOX™ emissions control technology has entered the carbon black industry.

Orion Engineered Carbons LLC has signed a contract for the technology, which will remove SOX, NOX and dust particles from tail gases at Orion’s carbon black plant in Ivanhoe, Louisiana, US.

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. Topsoe reports that Orion was convinced by the sustainability profile of the process, which does not consume any water or reagents, apart from ammonia for the NOX reduction. 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, license, 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 sulfur dioxide, nitrogen oxides, and particulates from flue gases. The sulfur is recovered as sellable sulfuric acid and the nitrogen oxides are reduced to harmless free nitrogen.
