More and more coke oven plants worldwide face the task to improve their emission reduction at their coke oven batteries. In the 90’s PROven was invented and developed by DMT to regulate the inner pressure of a single coke oven chamber. Generally, most of the coke oven chambers can only close and open their connection to the collecting main but without the possibility to regulate the pressure during the carbonization time. Through the installation of PROven the load on the coke oven door sealing system and the charging lids will be decreased and so does the emissions of crude COG as well. The current PROven system, installed in the collecting main, does not only regulate the chamber pressure, it replaces the valve between the goose neck and the collecting main, too. This variable pressure control allows decreasing the leakages at the emissions sources to a minimum and allows operating the collecting main under optimum pressure. Subsequently, this will lead to enhanced emission reduction. PROven proved its value with more than 2,100 units installed by licensee worldwide. Nevertheless, DMT is always focused on its client’s needs and therefore enhance PROven to provide the Best Available Technique (BAT). Among the main features of the now available system is the plain arrangement with a higher reliability and the possibility to install the system outside of the collecting main without modifying it. Hence, upgrading coke oven plants during operation is possible without any noticeable impact on the plant operation.
