In the mid 1980s, theCompriomo company fromNetherland combined the Claus reaction with the catalytic oxidation reaction on the basis of the traditional concept, successfully developed theSuperClausmethod and achieved industrialization on the scale of 100 t/d Claus device in 1988. At present, more than 130 industrial units ofSuperClaus (andSuper fine) process have been built around the world, and rich experience in design and operation has been accumulated. Highlyefficient selective oxidation catalyst and advanced burner control (ABC) system are the two most important key technologies ofSuperClausprocess. In recent years, theSuperClausprocess is combined with the new process technologies, such as oxygen-enrichedcombustion, dynamic wave alkali washing and so on, to deal with theleansour gas sulfurrecovery with high impurity componentsand more stringenttail gasemission requirements impurity components.
