Alliance refinery
Also known as:
Belle Chasse
Alliance was a refinery located on the Mississippi River, 25 miles south of New Orleans in Belle Chasse, Louisiana, in the US.
The refinery was 100% owned and operated by Phillips 66.
The refinery primarily ran light, sweet domestic crude. Crude was accessed from domestic pipelines and from the LOOP.
