Chemists experiment with chlorine gas for influenza immunizations at Chemical Warfare Service in the United States.
Experiments with chlorine gas for influenza immunizations in United States. A World War I tank sprays gas in a field. View of American soldiers during 1917 to 1918 period of World War I, in a trench, wearing gas masks, and firing rifles at enemy positions. Post war tests on use of Chlorine gas to control the flu (emerging from 1918 Spanish Flu epidemic), inspired by low rate of influenza among United States soldiers exposed to chlorine gas during the war. Man enters a chlorine chamber at the Chemical Warfare Service. A chart on the wall showing results on symptoms after exposure in chlorine chamber. A woman in 1920s hat carrying a tissue is treated with chlorine gas. A testing apparatus on a table. Group of patients sit together in a chlorine chamber being exposed to the chlorine gas. A business man in a suit receives a portable chlorine gas treatment in his office as he is too busy to visit the chlorine chamber.
The distillation of pure gasoline from crude gasoline through purification and further processing in steam stills.
Distillation of crude gasoline to remove impurities in United States. Still cleaners wear heavy clothing to protect themselves from intense heat. They work on the clearing of stills for further processing of the gasoline. The crude gasoline is placed into agitators for further purification. Gasoline is agitated with compressed air. Treatment operation is finished by washing with water. Crude gasoline is subjected to final distillation after chemical treatment for further purification. Further processing of the crude gasoline in the steam stills.
Crude gasoline is distilled for purification and fractionated in steam stills, United States.
Distillation of crude gasoline to remove impurities in United States. Animation shows the process of distillation of the crude petroleum. The still is charged with crude gasoline and steam is passed through perforated pipes. The vapors after this process are composed of steam and pure gasoline. They pass from condenser in the form of gasoline and water. The water settles to the bottom and the gasoline overflows. Stillman works in the factory. The gauge indicates the flow in barrels. Stillman controls the operation by watching the rate and gravity of steam. Gasoline is fractionated on re-running stills using fire and steam.
The cracking process is undertaken for obtaining further gasoline in United States.
Distillation of crude gasoline to remove impurities in United States. Cracking process to convert additional portion of crude oil into gasoline. Crude oil is distilled under high pressure. By this process, it cracks and yields 40% gasoline. Battery of pressure stills. Smoke arises from the stills during processing. Animation shows the process of further distillation of crude oil to obtain gasoline. The still is charged with crude oil. It is fired with mechanical stokers. A high pressure is created in still from which cracking takes place. Then the gasoline passes off as vapor with some heavy oil. Fractionation takes place. The heavy ends are returned for further cracking. Gas vapors are passed in condenser coil. Then it is passed in receiving drum. Excess gas is taken off to maintain an even pressure.
The processing and loading of the natural gasoline for shipment in refineries, United States.
The processing of gasoline to obtain natural gasoline. The casing-head or natural gas is recovered in oil field through oil wells. Gas is taken from casing-head. Gas is then compressed in the compression plant. The processing of gas in the plant. The compressed gas is cooled. Man loading natural gasoline for shipment in refinery. Tank car is filled through a tight cover. Filling the line. The gasoline vapor is recovered in an absorption plant.
