Abstract (en)

[origin: WO9962621A1] The invention relates to a method for purifying process waste gases by introducing them into a waste gas purification system that comprises a reaction chamber and by post-treating the reaction products that leave the reaction chamber in a washing chamber or sorbtion chamber with an associated washing agent circuit, whereby the type and amount of harmful substances in the process waste gas are continually measured before said waste gases enter the waste gas purification system (1); the type and amount of harmful substances in the reaction products that leave the waste gas purification system (1) are simultaneously determined directly at the exit of the said system (1); and the measuring signals are used directly in order to regulate the operating parameters of the waste gas purification system (1).
