Marathon Petroleum confirms successful test run for US refinery producing 100% renewable diesel based on Topsoe’s HydroFlex

In late 2020, Marathon Petroleum Corporation (Marathon) began the production of renewable diesel at its Dickinson refinery in North Dakota. Marathon now reports successful completion of the refinery’s test run of the grassroot renewable diesel unit, based on Topsoe’s HydroFlex technology.

The new HydroFlexx unit produces 100% renewable diesel from soy and corn oil with a capacity of 10,000 barrels-per-day.

Marathon will convet its Martinez refinery to renewable fuels production with an even larger capacity, said Jeff Sexton, Refining Technology Director, Marathon Petroleum Corporation.

With HydroFlex, customers can convert low value feedstocks to renewable fuels that qualify for the California Low Carbon Fuel Standard (LCFS) credit. The innovative HydroFlex process layout offers lower capital expenditure (CAPEX), but also a lower energy consumption during operation, resulting in a lower Carbon Index (CI). Topsoe’s HydroFlex™ can be deployed in both grassroots units and revamps for co-processing or stand-alone applications.
