Catalyst poison removal | Sulfur guards

Operating at lower temperatures can reduce a refinery’s operating costs significantly, but low operating temperatures negatively affect the saturation capabilities of traditional zinc oxide sulfur absorbents.

Able to remove hydrogen sulfide and other sulfurous compounds at temperatures below 150°C (300°F), Topsoe’s sulfur guards protect your downstream catalysts and ensure pipeline specifications, while helping you reduce operating costs. Our guards provide very high sulfur capacity and long life cycles, and are cost-effective and easy to install and operate under a wide range of conditions.
