VPSA Oxygen Plant Development

In 1891, the German company Linde began work on air liquefaction in the laboratory of the refrigeration machinery manufacturing company.
In 1895, Professor Linde made the first liquid air device using the Joule-Thomson effect.
In 1901, Linde established a cryogenic equipment manufacturing plant in Munich.
In 1902, the air separation equipment for the first single-stage rectification tower designed by Linde was completed. French Kraut invented the expansion machine and established the Air Liquefaction company in Paris.
In 1903, Linde made the first industrial 10m3/h oxygen generator, using a high-pressure throttling process.
In 1910, France made the first 50m3/h oxygen generator using a medium pressure process with a piston expansion machine.
In 1920, Hyland, Germany, invented a high-pressure process for producing liquid oxygen with a high-pressure expansion machine.
In 1924, Frankel suggested that in large air separation equipment, metal filled coolers should be used instead of ordinary heat exchangers.
In 1926, Frankel proposed the common form cold accumulator.
In 1930, Linde made the first industrial-scale Linde Frankel unit with a output of 255m3/h and a purity of 99.5%O2.
In 1932, the turboexpander was used for the first time on the Linde-Frankel unit. Oxygen was first used in metallurgy and ammonia synthesis in Germany.
In 1939, the Soviet Union created a high-efficiency turboexpander, and began to study the full low-pressure air separation equipment.
In 1947, Linde dedicated itself to the full bottom pressure industrial oxygen manufacturing equipment. The Soviet Union began to design large industrial oxygen plants with full low pressure processes.
In 1949, the United States for the first time in 29000m3/h oxygen generator on the application of plate warping heat exchanger.
In 1952, Austria first used pure oxygen top-blown converter to make steel, prompting a sharp increase in metallurgical oxygen.
In 1955, the United States vigorously developed missiles and consumed a large amount of liquid oxygen as an accelerant.
In 1957, the first automatically operated 120 tons/day oxygen generator was made.
In 1960, Japan completed 10000m3/h99.6%O2 and 10000m3/h99.99%N2 double high-purity large-scale full low-voltage equipment.
In 1972, France made the world's largest capacity of pure oxygen air separation equipment: 1700 tons/day O2 and 1500 tons/day N2.
Larger units are still under study.
