Abstract

PURPOSE: To reduce the amt. of a neutralizing agent used and increase the amt. of sulfuric acid recovered, by filtering high concn. sulfuric acid contg. soot obtd. from exhaust gas in a SOx absorption process after which the soot is washed with water and neutralized, and the washing soln. is recycled to the process.
