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'.
Men work in a fully-equipped and well managed laboratory in Indiana, United States. Equipment needed for conducting the tests in the laboratory. Winter operation checked in a cold room. Testing of aviation products. An airplane parked on the air base. Transparent glass bearing to test viscosity of oil. Drops of dyed glycerin with oil to make the action of lubricant visible. It helps in the study of partial lubrication. After passing the tests the lubricating oil is shipped into tank cars, barrels and cans for transportation.
The manufacture of grease to be used with lubricating oil in Indiana, United States. Grease is a mixture of lubricating oil and a soap. The soap is made in large mixers and then stirred with lubricating oil. Men manufacture the soap. Stirring of the soap with lubricating oil.
The testing of oil for its lubricating efficiency in Indiana. Man performs the 'viscosity test' of the lubricating oil in a laboratory. This test measures the time required for a fixed quantity of oil to flow through an opening of certain size , at a predetermined temperature. Three test tubes on table with light, medium and heavy oil having low, medium and high viscosity respectively.
A man determines the carbon forming tendency of oil in Indiana. This is done through actual tests on a motor. A man collects the carbon from the motor and weighs it. Test tubes on table contain different oils to determine which oil forms what amount of carbon. Test tubes of oil number 1, 2, 3 and 4 on the table and the amount of carbon formed by them.
The processing of lubricating oil from crude oil in refineries of Washington DC, United States. The purification of the lubricating oil by chemically treating it in agitators. Animation shows that the oil is pumped into the treating tank where it is treated with chemicals. By this, the asphaltic or the tarry material having no lubricating value settles down. The oil is then taken and is pumped into the wash tank for further treatment. In the wash tank, it is mixed with hot water and agitated with air which washes out the chemicals. This oil contains paraffin wax which has no lubricating value and has to be removed. The oil is chilled to remove the wax and then pumped under high pressure through large filter presses. Filter press is composed of steel ring. The side plates are made of perforated steel. A blanket cotton duck, cake space and distillate inlet. The oil is forced through press. Stillman performs the work. The oil is then divided into various grades of lubricating oil in the reducing stills.
