The Mineraloelraffinerie Oberrhein GmbH (MiRO) Refinery1, located on the Rhine River in Karlsruhe, in southwest Germany, is a joint venture with Phillips 66 holding an 18.75 percent interest.

Phillips 66 processes mainly medium sweet and medium sour crude oils in its share of the refinery. Crude is delivered to the refinery by a cross-country pipeline from the port in Trieste, Italy.

The facilities consist of three crude unit trains, fluid catalytic cracking, petroleum coking and calcining, hydrodesulfurization, naphtha reformers, isomerization, ethyl tert-butyl ether, and alkylation units that enable it to produce a high percentage of transportation fuels. Other products include petrochemical feedstocks, home heating oil, bitumen and anode and fuel-grade petroleum coke. Phillips 66 distributes the majority of its share of the refined products to customers in southwest Germany, northern Switzerland and western Austria by truck, railcar and barge.
