TopClaus®

Combining the best of Claus and WSA technologies

TopClaus® combines two well-proven technologies to achieve 99.9+% sulfur removal from acid gases – at significantly lower costs.

Conventional solutions struggle with high SRE demands
The current World Bank standards prescribe that Claus installations in refineries should emit no more than 150 mg/Nm3 sulfur dioxide, corresponding to a sulfur removal
efficiency (SRE) of 99.9+%. Refineries are struggling to comply with this at low cost.
