Haldor Topsoe and Comprimo announce a global strategic alliance on TopClaus® technology. The TopClaus® offering combines two well-proven technologies, the highly energy-efficient WSA process with the industry-standard Claus process. As a result, TopClaus® enables operators to handle acid gases and achieve sulfur removal efficiency (SRE) above 99.9%. Besides, the cost of ownership is significantly lower than with traditional technologies such as Claus followed by a conventional amine-based tail gas treatment unit.
The Claus part of the TopClaus® solution recovers elemental sulfur from acid gases. The tail gases from the Claus unit are then treated in the WSA unit, where the remaining sulfur compounds are converted into sulfuric acid. The sulfuric acid is returned directly to the Claus reaction furnace for reprocessing to elemental sulfur, with no sulfuric acid left as a by-product. However, sulfuric acid can be drawn off for specific uses or sale as desired.
