Lurgi Company

The German Lurgi Company and Linde A. G. developed the Rectisol process to use methanol to sweeten natural gas. Due to the high vapor pressure of methanol this process is usually operated at temperatures of -30 to -100°F. It has been applied to the purification of gas 1 plants and in coal gasification plants, but is not used commonlv natural gas streams.

In pilot plants identical with the Lurgi Company unit of the middle-pressure converter described above, simultaneous tests were run on six different iron catalysts (54). 

Some companies (e.g. Lurgi, Texaco) are best known for one process, even though they may have developed many others in general, only their most famous one is included here under the company name. Their other processes are included if they have special names. Process names which combine the names of two collaborating companies (e.g. Mobil/Badger) have mostly been included. Company names are usually given in the styles in use at the times of their respective inventions, as given in patent applications. 

Koppers-Totzek A coal gasification process using an entrained bed. The coal is finely ground and injected in a jet of steam and oxygen into a circular vessel maintained at 1,500°C. Reaction is complete within one second. The ash is removed as a molten slag. The process was invented by F. Totzek at Heinrich Koppers, Essen, and further developed by Koppers Company in Louisiana, MO, under contract with the U.S. Bureau of Mines. The first commercial operation was at Oulu, Finland, in 1952 by 1979, 53 units had been built. Most of the plants are operated to produce a hydrogen-rich gas for use in ammonia synthesis. Developed by Lurgi. See also PRENFLO. 

SHU [Saarberg-Holter-Lurgi] A flue-gas desulfurization process using wet limestone as the sembbing medium, assisted by the addition of dilute formic acid. Developed by the companies named, and used in 11 power stations in Germany and Turkey in 1987.
