    Sulfur removal | Sulfuric acid production

    Achieve compliance and maintain profitability

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

    Whether you are driven by a need to remove sulfur compounds from off-gasses, you want to produce sulfuric acid for sale or captive use, or both - it is possible to keep emissions low without excessive operating costs.

    Now, you can handle sulfurous off-gasses and convert sulfur compounds into commercial-grade, concentrated sulfuric acid with best-in-class energy economy. You can also produce sulfuric acid based on elemental sulfur as a stand-alone solution or in combination with off-gas treatment.

    Our WSA units reduce emissions in several industries including oil refining, natural gas upgrading, gasification, coking, metallurgy, viscose, and pulp and paper production.

    If you have a dry gas sulfuric acid plant and need a new catalyst charge, click here. The VK series of catalysts can help you achieve higher capacity, lower emissions or lower pressure drops simultaneously.

    Protect your profit with cost-effective sulfuric acid production solutions

    With our solutions and services, you gain the know-how and technology needed to produce your own sulfuric acid from sulfur or off-gasses. Pave the way for new business opportunities, create a cost-effective lifecycle, and protect your profit with sulfuric acid production solutions that solve challenges and create opportunities for your business.
