Topsoe technology selected for Indiana refinery
Topsoe has been selected as the renewable diesel technology partner for CountryMark’s Mount Vernon, Indiana refinery. Located in southwestern Indiana, the refinery processes 35,000 bbl/d of crude oil. With the addition of Topsoe’s HydroFlex technology, CountryMark aims to produce up to 250,000 barrels of renewable diesel annually. The new unit is expected to enable an emission avoidance of approximately 84,500 t/a of CO2e. CountryMark, a farmer-owned cooperative, will use local soybean oil as the primary feedstock to produce renewable diesel, helping create a locally sourced renewable fuel economy in Indiana.
Henrik Rasmussen, Managing Director of Topsoe Americas, said: “Our collaboration with CountryMark goes back many years. With demand for renewable diesel continuing to grow, we’re excited to partner with CountryMark on their journey to produce cleaner fuels and contribute to America’s low-carbon energy future.”
Matt Smorch, CountryMark President and CEO, added: “We saw this as an opportunity to deliver increased value to CountryMark diesel fuel buyers, increase the demand for Indiana agricultural products, and add value to our refining assets.”
