Modern catalyst management regenerating, activating and optimizing SCR-DENOX catalysts upon activity loss and increase in SO{sub}2 to SO{sub}3 conversion

摘要

Regenerating used catalysts is an interesting alternative to replacing them by new ones, both from the ecological and economic points of view. Integral Umwelt- und Anlagentechnik GmbH ("IUT"), a subsidiary of the Integral Group, has developed a highly efficient and economical regenerating process. The company has drawn upon consolidated knowledge and comprehensive experience in the areas of building and operating all types of SCR-DENOX and De-Dioxin equipment, based on years of engineering, construction, and after-sale service of a multitude of nitrogen-oxide removal equipment units throughout Europe and Asia. The range extends from about 5,000 to 2,000,000 Nm{sup}3/h of flue gas in high-dust or low-dust applications for all fossil fuels in power plants, as well as diesel engines, to industrial processes and the incineration of municipal solid waste and hazardous waste.
