COMPANY TECHNOLOGY APPLICATIONS CONTACT FLEX Desulfurization Auterra’s technology exploits the natural tendency of oil’s impurities to oxidize Tradtional Hydroprocessing Auterra’s Flex Desulfurization HDP reduces sulfur by heating oil to very high temperatures and adding high-pressure hydrogen to force a chemical reaction to separate impurities from the oil. Heavier oil feeds require higher temperatures, resulting in more utility usage and GHG emissions. Auterra’s process adds oxygen to remove sulfur and other impurities in oil by catalyzing an oxidizing reaction at room temperature. This process significantly reduces capital & operating costs and GHG emissions. FlexULS REMOVES HUNDREDS OF PPM OF SULFUR Auterra’s FlexULS technology removes remaining sulfur from fuels and petrochemical streams, so producers can sell them as in-spec products with less discounting. LEARN MORE FlexUP REMOVES PERCENTAGES OF SULFUR FlexUP technology from Auterra removes sulfur and impurities in heavy oils, bitumen, and marine fuels in a two-step process that preserves oil mass and results in higher-value product. LEARN MORE Auterra Successfully Reduces Sulfur UntreatedAuterra Treated Auterra avoids a major drawback of HDP: high levels of impurities found in heaviest oil quickly deactivate HDP catalysts Hydroprocessing’s drawbacks threaten oil producers: Environmental Harm HDP requires high process intensity. Units emit significant greenhouse gases and are utility-intensive. Capital Intensive Replacing aging HDP units will require significant capital expense with no decarbonization benefits. Large Footprint Hydrogen gas is only cost-effective at large scales, requiring large units that can’t treat distributed inventories Prone to Poison HDP is ineffective treating heavy crudes, as impurities in those fuels quickly deactivate HDP catalysts. FLEX DESULFURIZATION PROCESS Auterra’s sulfur oxidation & removal process Flex eliminates many drawbacks of hydroprocessing and gives producers a greener, more cost-effective option to generate in-spec and higher value oil products LEARN ABOUT APPLICATIONS FlexULS: Sulfur Polishing Marine fuels, transmix, and other feedstocks less than 1,000 ppm FlexUP: Deep Removal Producers of heavy sour crude, bitumen, and refineries RESOURCES Privacy Policy Accessibility Statement A CLEANER, GREENER OIL TREATMENT Auterra develops projects and licenses Flex desulfurization technology as a low-cost, low-carbon treatment option to reduce sulfur and impurities in fuels and oil feedstocks.
