The 4th Daughter Directive to the Air Quality Directive sets, for year 2012, a target value of 1 ng/m3 for the concentration of benzo(a)pyrene in ambient air. This target cannot be met at present in the ambient air of numerous coke plants. Operators are thus requested to take every reasonable measure in order to come closest to the desired air quality standard. Technical measures for minimizing benzo(a)pyrene emissions will focus on optimizing the pressure conditions in the oven chamber as well as on improving the sealing capabilities of coke oven closure facilities. The techniques for reduction of benzo(a)pyrene emissions, developed by Deutsche Montan Technologie GmbH, are presented.
