The report gives results of an assessment of the multimedia environmental impacts of continuous wet and dry quenching at National Steel's Weirton, West Virginia, Brown's Island coke plant. The report, based primarily on design data, test data from related processes, and engineering judgement, suffers from the lack of definitive test data. The assessment indicates that dry coke quenching results in less particulate matter emitted, less solid waste generated, less process-related gas emitted, and potentially less emission of polynuclear aromatic hydrocarbons and organics in general, than wet quenching. Dry coke quenching also results in increased aqueous effluents and fugitive emissions from coke transport and screening. The assessment concludes that, with proper wastewater treatment and control of coke transport emissions, the dry quench process should have less negative environmental impact than continuous wet quenching. The report identifies areas where data are insufficient for Level 1 assessment and indicates the testing required for a complete Level 1 assessment.
