Purification of waste gases in the desulfurization of coke-oven gas

Purification of waste gases in the desulfurization of coke-oven gas The operation of equipment for the hydrolysis of waste gases from the desulfurization of coke-oven gas is analyzed on the basis of chromatographic data. Specifically, the data relate to the operation of such equipment in shop 2 for trapping coking byproducts at OAO Magnitogorskii Metallurgicheskii Kombinat, over a period of four years (2004–2008). The reduced efficiency of the system in the third year of operation is due to sharp deactivation of the CR-31 aluminum-oxide catalyst (La Roche Chemicals) in the R-6301 reactor on account of sulfate formation on opening the reactor. In normal operation, the life of the catalyst in the R-6301 reactor is at least 2–3 years. To restore the efficiency of hydrolysis, the catalyst in the R-6301 reactor must be completely replaced, preferably with a specialized catalyst for hydrolysis and hydrogenation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Coke and Chemistry Springer Journals

Abstract

The operation of equipment for the hydrolysis of waste gases from the desulfurization of coke-oven gas is analyzed on the basis of chromatographic data. Specifically, the data relate to the operation of such equipment in shop 2 for trapping coking byproducts at OAO Magnitogorskii Metallurgicheskii Kombinat, over a period of four years (2004–2008). The reduced efficiency of the system in the third year of operation is due to sharp deactivation of the CR-31 aluminum-oxide catalyst (La Roche Chemicals) in the R-6301 reactor on account of sulfate formation on opening the reactor. In normal operation, the life of the catalyst in the R-6301 reactor is at least 2–3 years. To restore the efficiency of hydrolysis, the catalyst in the R-6301 reactor must be completely replaced, preferably with a specialized catalyst for hydrolysis and hydrogenation.
