Haldor Topsoe A/S has announced that Orion Engineered Carbons LLC has signed a contract for its sustainable flue gas cleaning technology, SNOXTM.

The technology will remove SOX, NOX and dust particles from tail gases at Orion’s carbon black plant in Ivanhoe, Louisiana, US. It is the first time that SNOX will be applied in the carbon black industry.

According to the statement, Orion has conducted in-depth analyses of the SNOX process since 2014, 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 sustainability profile of SNOX, which does not consume any reagents except for ammonia for the NOX reduction, and does not consume any water. Also important to Orion’s decision to use the technology was the highest available energy efficiency and the low emissions levels that meet strict environmental regulations.

This agreement with Orion includes engineering, license, proprietary equipment, spare parts, catalyst and future supervision tasks during commissioning and startup, as well as service obligations during commercial operation. The plant is scheduled to commence full commercial operation by April 2021.

The SNOX process removes sulfur dioxide, nitrogen oxides and particulates from flue gas. The sulfur is recovered as sellable sulfuric acid and the nitrogen oxides and reduced to harmless free nitrogen. The process is based on catalytic reactions and does not consume water or absorbents. In addition to this, it does not produce any waste.

The heat that is generated in the process can be reused to preheat air in Orion’s process, which improves overall efficiency and economics considerably.
