2000x650 Application Sulfur recovery

Turn your sulfur emissions into commercial opportunities

Sulfur emissions standards are tightening worldwide, forcing industrial, chemical, refining, and metallurgical operations to compromise profitability to meet legal requirements.

Sulfur recovery solutions are a vital part of the picture when it comes to making the most of wasted sulfur compounds. If you want to balance profitability and compliance, Topsoe’s sulfur recovery solutions make it possible. Both TopClaus® and WSA technologies take sulfur compounds that were once seen as waste and transform them into valuable elemental sulfur or sulfuric acid. Ensure high sulfur recovery, outstanding reliability and the industry’s lowest investment and operation costs with TopClaus®.

If you want to produce sulfuric acid, WSA technology provides the market’s best energy economy, generating useful high pressure, superheated steam and lowering the carbon footprint of your operations.


Protect your profit with cost-effective sulfur recovery solutions

With our solutions and services, you gain the know-how and technology needed to convert sulfur compounds into commercial grade concentrated sulfuric acid or high-quality elemental sulfur. Pave the way for new business opportunities, enhance your energy efficiency, and lower your carbon footprint with sulfur recovery solutions that solve challenges and create opportunities for your business.
