Abstract. Coke oven emissions are the volatile products that are released from bituminous coal during its conversion to coke in high temperature ovens in the absence of air. These emissions arise from the noncarbonaceous materials present in the coal prior to processing and are complex mixtures of dusts, vapors, and gases that typically include polycyclic aromatic …
