COMPANY TECHNOLOGY APPLICATIONS CONTACT 65% less greenhouse gas emissions than hydroprocessing 50% lower capital and operating costs than hydroprocessing Flex Desulfurization: Low-cost & Low-carbon Auterra’s family of patented process technologies and catalysts are proven to reduce sulfur with significantly lower cost and GHG emissions Robust Catalysts Auterra’s impurity-resistant catalysts and benign process conditions improve stream value to keep fuels in-spec or enable producers to upgrade feedstocks Flexible & Affordable A small physical and carbon footprint for Auterra’s treatment units opens opportunities to effectively desulfurize small volumes and heaviest feedstocks Green and Clean Room-temperature oxidation reactions remove oil impurities with significantly less CO2 emissions and hydrogen demand versus traditional hydroprocessing FlexULS: Sulfur Polishing Auterra’s process for polishing off-spec fuels LEARN MORE FlexUP: Deep Sulfur Removal Oxidation and removal of impurities creates high-value oil LEARN MORE “It’s a fight for survival in the ESG world. It’s not enough to be the cheapest barrel now. You have to be the greenest barrel now.” Helima Croft, Head of global commodities strategy, RBC THE SULFUR PROBLEM Oil treatment technology gaps are costing the industry billions Auterra’s Flex desulfurization technology is a proven solution when hydroprocesing is economically or environmentally prohibitive Hydroprocessing isn’t economically viable for smaller volumes of fuel that need sulfur polishing New international and regional limits require continued sulfur reductions in marine fuel and home heating oils With $51 billion invested in ESG funds in 2020, oil producers must meet environmental commitments Approximately 60% of US refinery GHG emissions comes from process heat, including hydroprocessing 0% increase in sulfur content in crude oils sent to refineries in last 30 years 0 barrels per day are heavily discounted as “off-spec” due to high sulfur content 0 metric tons of GHG emitted annually by average refinery, second only to power plants LEARN HOW AUTERRA ADDRESSES THE GAPS APPLICATIONS Keep fuels in-spec and preserve oil mass Auterra’s patented Flex desulfurization technology works for lighter streams to improve assay quality with minimal hydrogen use, and for upgrading heavy crudes while preserving oil mass and increasing feedstock value. Sulfur Polishing Pipeline transmix, fuels polishing, petrochemicals polishing Deep Sulfur Removal Crude upgrading, bitumen and extra heavy sour treatment, heavy fuels treatment SEE ALL APPLICATIONS FLEX DESULFURIZATION PROCESS Desulfurization reduces GHG emissions and upgrades oils Auterra is a better way to desulfurize oil and it’s less cost-intensive than hydroprocessing.
