For the Biofuels & Renewables Industry

Merichem Technologies offers proven, cost-effective solutions for sulfur extraction, helping renewable fuel producers get their products up to spec while meeting project cost and schedule goals.

Solving the sulfur problem

As producers aggressively embrace production of renewables, operators increasingly need a reliable, cost-effective process for removing sulfur—getting their renewable fuels to meet or exceed EPA specifications while also meeting the production facility SO2 emissions requirements.

Merichem Technologies’ LO-CAT® technology is a proven, proprietary, chemical-based sulfur-removal system that can effectively get renewable fuels to meet product specifications. Highly efficient for plants producing one or more tons of sulfur per day, it offers low operating costs paired with high efficiency of H2S removal. There are no liquid waste streams or hazardous waste products produced. Applications include:

  • Renewable diesel refining
  • Digestor gas from agricultural plants
  • Synthesis gas (syngas)
  • Garbage-to-power processes
  • Garbage-to-fuel processes
  • Landfill gas
  • Forestry waste, used cooking oil, animal-fat feedstocks

Caustic extraction of sulfur

Since 1980, the Merichem Technologies’ THIOLEX™ system has offered refiners a flexible alternative for the extraction of H2S and other acid gasses, reducing OPEX, CAPEX, and space requirements. While LO-CAT® is designed for high concentrations of CO2, THIOLEX™ is best for treating streams with low CO2 content. THIOLEX™ uses our proprietary FIBER-FILM® Contactor as the mass transfer device with caustic as the treating reagent in liquid and gas hydrocarbon streams.
