Resumo

With decreasing limits on allowable emissions on coke plants, one of the most effective emissions reductions strategies is single oven pressure control that allows the independent pressure control for each oven disregarding the collector main pressure set point. This strategy is known to greatly reduce, if not eliminate entirely, coke oven door, standpipe lid and filling port emissions by maintaining the collector main under negative pressure whilst maintaining a positive pressure in each oven throughout the carburization process.Paul Wurth has developed their Sopreco© (Single Oven PREssure COntrol) valve that allows the collector main to be kept at a negative pressure. The first generation Sopreco© Version 1 valve was internal to the collector main and was integral with the shut off valve (damper pan).
