Approximately 65 per cent of the The Ohio Oil Company purchased the site total circulating water is supplied by electricdriven pumps and the remainder by pumps driven by Elliott steam turbines.

To provide the necessary additional process ing steam and electrlcpower required by the new facilities, two 100,000-Ib-per-hr steam genera tors, producing 650 psig steam at 750 F total tem perature and two Elliott 5000-kva condensing turbine-generators were added to the existing power plant. Steam at 650 psig from the steam generator is reduced to 150 psig for distribution to the processing units, Blliott motors drive the forced- and induced-draft fiaqs, condenser circu lating water pumps (see illustration on page 9)i Summer l$}0 of the present refinery In 1924 from the Lincoln Oil & Refining Co., at which time the refining capacity was about 1000 barrels per day. The crude at this time was processed in small hori zontal shell stills. In 1926 the capacity of the re finery was Increased to 5000 barrels per day by the addition of a pipe still and thermal cracking facilities. The crude capacity was then gradually increased over the Intervening years to 15,000 barrels per day by alterations end modifications of the equipment. The recent expansion and modernization program represents the second major expansion for the Robinson refinery and results In a completely modern plant, capable of producing petroleum products of the high est quality. 11
