Smallest oil refinery

Founded in 1933, the C & H refinery (named after co-founders Roy Chamberlain and Jim Hoblich), based at Lusk, Wyoming, USA, is the world's smallest, processing just 190 barrels of crude oil a day. The refinery sells gasoline directly to retail customers from a service station adjacent to the works. The site was recently bought by Zahir A. Khalid (Pakistan) who plans to restore the ageing plant to it's former glory.
