At this time, thirteen commercial CANSOLV SO₂ Scrubbing Systems are in operation and many more are in the detailed engineering or procurement phase. Building on its knowledge of amine based technologies, the  CANSOLV SO₂ Scrubbing System is a revolutionary regenerable sulfur dioxide (SO₂) scrubbing process. This patented technology uses an aqueous amine solution, CANSOLV Absorbent DS, to achieve high selective absorption of sulfur dioxide from a large variety of gas streams. The scrubbing by-product is pure water saturated SO₂ gas, recovered by steam stripping which can be converted to sulfuric acid or sulfur. Both the CANSOLV SO₂ Scrubbing System and the absorbent have excellent health and safety properties.

The benefits of the CANSOLV Absorbent DS include:

• Elimination of high cost consumable reagents and associated transportation costs; 
• No environmental legacy obligations and costs;
• Reduced capital costs due to its high capacity and selectivity;
• Minimal emission of effluents from the process.
