The Great Falls refinery is a very small, medium complexity refinery located in Great Falls, Montana in the US.
The refinery is 100% owned and operated by Calumet Specialty Products.
The refinery processes Canadian heavy crude and produces a large amount of asphalt for the local market.
There is a project currently underway to convert the hydrocracker to produce renewable diesel and SAF, and lower overall crude throughput to 10-12 kbpd while still maintaining asphalt production.
The refinery is very small and low complexity in line with being a niche market, specialty products (asphalt) focused plant. It has a very over-sized hydrocracker relative to distillation.
