Smarter Sulfur Solutions solve your challenges

Flue Gas Desulfurization (FGD)

  • SNOX™ technology removes SO2, NOx, particulates and mercury from flue gases without limestone consumption and without generating waste materials.

Sulfur Recovery (SRU)

  • WSA technology recovers sulfur from waste streams in the form of concentrated, commercial grade sulfuric acid in a highly energy efficient way.
  • TopClaus® technology combines the well-known Claus technology with WSA to recover sulfur from H2S gases in the form of elemental sulfur in the most efficient way, both with respect to CAPEX and OPEX. TopClaus® is applicable for green-field projects and revamps.
