Alternative Control Techniques Document: PM-10 Emissions from Selected Processesat Coke Ovens and Integrated Iron and Steel Mills

摘要

The purpose of the document is to provide guidance to state and local air qualitymanagement agencies for determining reasonably available control technologies (RACT) and best available control technologies (BACT) that apply to PM-10 sources in the iron and steel industry. Emission sources addressed are coke pushing, coke quenching, coke sizing and screening, casthouse operations, hot metal transfer, and desulfurization. These sources were selected for analysis because they are not presently regulated under New Source Performance Standards (NSPS). Emission control system descriptions, environmental and energy impact assessments, and control cost analyses are presented. The principal emission collection devices used are the fabric filter and wet venturi scrubber.
