Scene shifts to a U.S. Army Air Force P-47D aircraft flying over the training area as it comes in for a landing at Hammond Army Air Field.
The processing of creating lubricating oil from crude oil in refineries in, Indiana, United States. Crude oil is taken to the refineries from various oil field through pipelines and tank cars. Smoke from the chimneys of refineries. The first method in the processing of lubricating oil is the distillation of the crude oil in pipe stills. Animation shows the distillation in a simple shell still. Distillation of the other non-lubricating parts from the crude oil. As the temperature rises, the steam is turned into still. It lowers the boiling point and prevents the 'cracking' process. Then the light lubricating oil condenses first and then the heavier portion. The remainder called the 'residuum' is sent to the asphalt department for further refining into asphalt, road oil. A still man controls the operation of the distillation process at the 'receiving house'.
The processing of making lubricating oil from crude oil in refineries in Indiana. The lubricating oil is further purified by passing it through a 15 foot Fuller's earth bed in large filters. Animation shows that the filter is charged with fuller's earth. The oil is passed into the filter. The oil percolates through the fuller's earth and becomes lighter in color. The clay is withdrawn after it completes its work from the filter and is burned for reuse in a revolving kiln. The filtered lubricating oil is then pumped into storage tanks.
The process of gaining lubricating oil from crude oil in steam and fire stills in Indiana, United States. Smoke from the chimneys. The distillation of the crude oil takes place. Animation shows the process. Steam is passed into the still to prevent the 'cracking' process. The lighter portion of the oil vaporize and condense first. Then the oil is treated chemically, freed from wax, filtered and sent to storage. The remainder called the 'bottom stock' is treated with chemicals to remove further impurities. The stillman performs the process. This oil contains petrolatum which is to be removed. It is mixed with naphtha and chilled in cold settling tanks. The petrolatum settles to the bottom of the tank due to this process.
