Sulfur recovery technology
Sulfur recovery technology The production of sour natural gas and the refining of higher sulfur content crude oils is increasing in the world today. The need to recover sulfur from hydrogen sulfide produced from such sources is also on the rise. In today's society there is an increased concern about the potential threat of air pollution to the well-being of mankind. Therefore, the various technologies for removing and converting hydrogen sulfide to elemental sulfur are gaining increased importance in industry. The Claus process was invented by an English scientist named Carl Friedrich Claus and a patent was issued to him in late 1883. In 1938, a German company called I.G. Fabenindustrie A.G. made a significant modification to the original Claus process; and thus, the Modified Claus Process was born. Today the majority of sour gas that is processed in the United States and throughout the world, and the majority of sour crude oil refined in the world produces hydrogen sulfide which is eventually converted to elemental sulfur by the Claus process. Other technologies have emerged down through the years; but, none have ever come close to making the impact on industry that the Claus process has achieved. It is estimated that some 90 more »
