Polmin
Polmin (English: State Factory of Mineral Oils, Polish: Państwowa Fabryka Olejów Mineralnych) was a Polish state-owned enterprise, which controlled excavation, transport and distribution of natural gas. Founded in 1909, it was nationalized in 1927, with main office in Lwow. Polmin operated a large oil refinery in Drohobych, which in late 1930s employed around 3000 people. The refinery purified oil extracted from rich fields of southern part of the Second Polish Republic ( Gorlice, Boryslaw, Jasło, and Drohobych). Some Polish-language sources claim that Polmin refinery in Drohobycz was in late 1930s the biggest in Europe.
