For Specialty Processing Applications

Featuring a highly flexible design and cost effective advantage, Merichem’s patented LO-CAT® process has applications for removing H2S from most types of gas streams.

Designed to Accommodate

Delivering 99.9% removal efficiency, LO-CAT® technology has been proving its value for more than 35 years. Its highly flexible design allows 100% turndown in gas flow and H2S concentrations, with applications in most types of hydrocarbon streams, including:

  • Air
  • Amine Acid Gas
  • Associated Gas
  • Biogas
  • CO2
  • Coke Oven / Syn Gas
  • Flue Gas
  • Fuel Gas
  • Landfill Gas
  • Natural Gas
  • Wastewater Off Gas

Engineered for Efficiency

With a single treatment step, Merichem’s LO-CAT® economically removes hydrogen sulfide to the levels required by your processing needs. The H2S is converted to solid sulfur at low temperatures, then filtered from the process loop, with no effluents or waste products to handle. With the catalyst continuously regenerated, operating expenses are minimized significantly.

Merichem’s project expertise focuses on the comprehensive support of engineering, design, project management and the fabrication of treatment systems for our customers worldwide.
