“…The joint removal of NH 3 and H 2 S from COG using the Ama-sulf technology was thus introduced. This approach involves the partial oxidation of H 2 S and the simultaneous decomposition of NH 3 over a Ni catalyst at 1100°C to 1200°C [34,35].…”

Coke oven gas treatment plants are well equipped with distributed control systems (DCS) and therefore recording the vast amount of operational data efficiently. Analyzing the stored information manually from historians is practically impossible. In this study, data mining technique was examined for lowering the ammonia concentration in clean coke oven gas. Results confirm that concentration of ammonia in clean coke oven gas depends on the average PCDC temperature; gas scrubber temperatures stripped liquor flow, stripped liquor concentration and stripped liquor temperature. The optimum operating ranges of the above dependent parameters using data mining technique for lowering the concentration of ammonia is described in this paper.
