Current desulfurization costs can account for >100% of the energy value for high-S resources; efficient gas cleanup is essential for economic resource utilization. Scalability and cost of SourCat™ technology is superior to established technologies across a range of desulfurization scales.

The patented SourCat™ desulfurization process employs a unique and proprietary catalyst that promotes the partial oxidation of H  S and mercaptans to elemental sulfur. The catalyst is highly selective to elemental sulfur over SO  . It can achieve high yield to elemental sulfur under a wide range of pressures, oxygen-to-sulfur ratios, and inlet sulfur concentrations. The catalyst has been evaluated in long-term bench scale evaluations where a single catalyst charge maintained high activity for over a year, even in the presence of contaminants such as ammonia and metal halides. The modular system has been evaluated at pilot scales where 95+% conversion of    H  S and COS to elemental sulfur was achieved in coal/biomass-derived syngas and in natural gas.




Process Selection & Design

IntraMicron's desulfurization suite is a unique answer to sulfur removal in gas streams. It's both a modular and tailor-made solution for removing 10 ppm to 10% sulfur species from gas streams with flowrates of 50 MSCFD to over 10 MMSCFD. Modules can be transported to remote locations and controlled by off-site operators. The outlet sulfur concentration of the gas can be customized based on the application's thresholds. To discuss a desulfurization system to match your application, please email and one of our application engineers will be happy to discuss it with you!

Benefits of Employing IntraMicron's catalytic desulfurization system:
  • Up to 75% Reduction in total desulfurization cost compared to current state of the art approaches at numerous scales

  • Up to 31x reduction in reactor volume (at 2500 ppm H  S)

  • Up to 85x solid waste reduction (at 2500 ppm H  S)

  • Converts majority (up to 99+%) of H  S to elemental sulfur (a usable by product) without significant SO  production!

  • Optimal adsorbent utilization with bed life sensor (if needed)

  • Easily accommodates varying sulfur levels
