Claus, Carl

CLINSULF [Carl von Linde sulfur] A variation of the Claus process in which the heat from the process is used to heat a second catalytic reactor. The process is designed for gases rich in hydrogen sulfide. First commercialized in 1992 and offered by Linde, Munich. 

He name is frequently written Carl Ernst Claus It is a German name, not a Russian one. 

The next major theory of metal ammines was proposed by Carl Ernst Claus (1796—1864). In 1854, Claus rejected the ammonium theory and suggested a return to Berzelius view of complexes as conjugated compounds. He compared the platinum ammines not with ammonium salts nor with ammonium hydroxide but with metal oxides. He designated the coordinated ammonia molecule as passive, in contrast to the active, alkaline state in the ammonium salts, where it can easily be detected and replaced by other bases .

Carl Claus in 1854 wrote a rather succinct study of the transition metals in general and platinum in particular (8). In this book he predominantly used the linear notation shown below. 

Finally, in 1844, Russian chemist Carl Ernst Claus (also known as Karl Karlovich Klaus 1796—1864) gave positive proof of a new element in platinum ores. Many authorities now call Claus the discoverer of the element. Claus suggested calling the element ruthenium, after the ancient name of Russia, Ruthenia. Osann had suggested that name as well.

Carl Ernst Claus (Dorpat (Tartu) ii January 1796 (O.S.)-24 March 1864) qualified as a pharmacist in St. Petersburg (Leningrad) and Dorpat, and practised in Kazan (1826). In 1831 he became assistant in chemistry in Dorpat but returned to Kazan in 1837 as associate professor of chemistry, professor in 1843. In 1852 he returned to Dorpat as professor of pharmacy, where he continued work on platinum metals. In 1834 he explored with Goebel the steppes between the Urals and the Volga, receiving the Demidov prize, and he also worked on botany.

Hydrogen sulfide partial oxidation is an exothermic process for converting hydrogen sulfide into elemental sulfur and water. A Claus plant (named for London chemist Carl Friedrich Claus) is a typical example of hydrogen... 

Claus Sulfur Recovery Process, At the sulfur plant, H2S is combined with sour-water stripper off-gas and sent to a Claus unit. Invented in 1881 by Carl Freidrich Claus/ almost every refinery in the world uses some version of this process to convert H2S into elemental sulfur. A simplified version of Claus-reaction chemistry is shown in Figure 26.
