Explanation with diagrams, of the oil refining process and oil refining techniques in 1925
Using a beaker labeled crude oil, a man demonstrates that it yields petroleum products of 30% gasoline, 20% kerosene, and 42% lubrication oil and wax, and 5% coke. Animated diagram shows layers of rock and wells being drilled to various depths to tap oil reservoirs, avoiding water pockets. Another chart shows successive layers of natural gas, oil and salt water that may be encountered. On the surface, the boiler, mud pond, derrick, engine and pump are identified at drilling site. Well casing, drill and movement of drilling products are illustrated.
Preparing drilling bit and drilling for oil in the United States
Sharpening an oil drilling bit. A worker holds hot steel oil drill (bit) with tongs. Another worker pounds it with a sledge hammer. A fish tail is fashioned into the bit.The newly sharpened fishtail bit,now fastened to the end of a drill shaft, is lowered into the drill hole. Then a heavy steel pipe is forced down into the drill hole. Roughnecks fasten the new section of pipe to another above it and lower the pipes and drill into the hole. At a depth of 2300 feet, The well yields muddy water with traces of oil in it. Supervisors, in a group, check carefully for the presence of oil.
Nitroglycerin is used to "shoot" an oil well in the United States
Oil drillers "shoot" a well by exploding nitroglycerine in the oil sand. Man is seen pouring liquid nitro-glycerine into a device at the well. A man poses holding a drill bit. The exploding nitro, deep in the well, creates a gusher. Crude oil is seen gushing from the well hole. Roughnecks work to cap the gusher. Construction workers build temporary storage tanks for oil from the well.
Crude oil being transported through pipe lines from the point of extraction to a refinery in United States.
Views of pipe lines for transportation of crude oil in United States. Shows a pipe line across a canyon. Workers dig trenches for a pipe line. Horse-drawn wagon loaded with pipes. Pipes stacked on ground. Railroad cars, teams and wagon in background. View of oil camp, mules, wagons, workers and a wooden bridge. Oil tank cars at a railroad yard transport crude oil. Crew at work on the deck of an oil tanker.
Fractional distillation of crude oil at an oil refinery in United States.
Separation of crude oil into various components at a refinery in United States. Crude oil in the still is divided by heat into gasoline, fuel oil, lubricating oil and many by-products. Animated diagram shows a tank of crude oil with fire under it and a pipe leading to a condenser. Naphtha and gasoline distillate, kerosene distillate, lubricating oils, paraffin distillate, coke and other by products are obtained. A worker shovels coke out of the door at base of the still. Workers load coke into wheelbarrow.
Impurities in gasoline are checked by hydrometers at a refinery in United States.
Modern methods of oil refining in United States. Hydrometers check gasoline for any impurity at a refinery in United States. The first vapor from the still is condensed into gasoline. It is then tested by hydrometers. Worker checks hydrometers. The impurities in gasoline are removed using sulphuric acid and agitators. Panoramic view of refinery.
