    Maximize Sulfur Recovery and Sustainability with Topsoe’s Proven Technologies

    If you are looking for solutions to help you stay on top of sulfur recovery efficiency, Topsoe's sulfur recovery technologies are a great place to start. 

    As sulfur emissions standards tighten worldwide, oil and natural gas operations face challenges balancing profitability and compliance. Our solutions can turn these challenges into valuable opportunities.

    How Topsoe sulfur recovery works 

    By choosing Topsoe's sulfur recovery solutions, you can convert sulfur containing streams such as acid gas, sour water stripping (SWS) gas and others into commercial-grade concentrated sulfuric acid or high-quality elemental sulfur. This ensures compliance, opens new business opportunities, and enhances energy efficiency. Plus, you will do your part to protect the environment and meet sustainability goals by reducing your carbon footprint.

    Topsoe offers two sulfur recovery solutions:

    For elemental sulfur production, TopClaus® offers outstanding reliability and the industry’s lowest investment and operation costs, ensuring high sulfur recovery and a boost to your bottom line.

    For sulfuric acid production, WSA technology is the market leader in energy efficiency, generating useful high-pressure superheated steam while lowering your carbon footprint.

    Both solutions are highly applicable to the oil and gas industry, which is subject to strict environmental regulations. By implementing these solutions, companies can ensure compliance with these regulations while boosting profitability and creating new revenue streams.

    Catalysts for sulfur removal

    VK-WH catalyst

    VK-WH catalyst

    VK-WH is a cesium-promoted catalyst designed for continuous operation down to 370°C/700°F in medium- to high-strength SO2+SO3 gasses.
    VK-WL catalyst

    VK-WL catalyst

    VK-WL is a cesium-promoted catalyst designed for continuous operation down to 370°C/700°F in lean SO2+SO3 gasses (less than approximately 2 mole%).
    VK-WSA catalyst

    VK-WSA catalyst

    The VK-WSA formulation offers excellent activity over a wide range of operating conditions and can be used in any bed of a WSA or WSA-DC converter.
    VK-WSX catalyst

    VK-WD catalyst

    VK-WD catalyst

    VK-WD is optimized for lean SO2+SO3 gases, such as in a SNOX™ plant or in the bed(s) after the ...
    ST-201 catalyst

    ST-201 catalyst

    A copper based absorbent used for remove minute amounts of sulfur compounds.

    Applications within this area

    Sulfuric acid production

    Sulfur emissions standards are constantly tightening, forcing industrial, chemical, refining, and metallurgical operations to find ways to comply with legislation.

    Spent acid regeneration

    Turn your challenges into opportunities today by partnering with Topsoe and taking advantage of our know-how, technology, and services for spent acid regeneration.

    Flue gas treatment

    Topsoe's flue gas treatment solution, SNOX™, helps you overcome FGD's common challenges by recovering sulfur as commercial-grade sulfuric acid, instead of as gypsum. 

    Treatment of sulfurous off-gasses

    Treatment of sulfurous off-gasses - maximizing sulfur recovery from off-gasses is vital for today's oil and gas industry.
