Improved emission calculations for PM{sub 10}, SO{sub 2} and H{sub 2}S from coke oven battery fugitive sources
- George Mason Univ., Fairfax, VA (United States)
National Ambient Air Quality Standards (NAAQS) specify the allowable limit of particulate matter in ambient air. Particulate Matter, under 10 micron size (PM{sub 10}), is the inhalable part of total suspended particulate in air with direct adverse impact on human health and environment. To have a better understanding of fugitive emissions from coke oven doors, lids, offtakes, pushing, hot car travel and quenching, EPA has conducted studies and published factors for emissions from most of those sources. Unfortunately, many of those field tests were performed in the 70`s and 80`s, and the developed emission factors may no longer be valid for present day coke plant operation. To identify the sources of PM{sub 10}, H{sub 2}S and SO{sub 2} and to account for their loading in ambient air samplers, fugitive emission estimation from Clairton Works battery sources, such as decarbonization, soaking, guide machine leaks during pushing and hot car travel were included in the emissions inventory. With the idea of developing accurate emissions rates from those sources, Clairton personnel took a different approach. They went to the basics of coal carbonization. The authors of the paper gathered operating data regarding average flue temperature in batteries, tons of coal charged, coking time, decarbonization and soaking time in all the batteries of Clairton for a month and estimated the fugitive emissions from soaking, decarbonization, pushing, hot car travel and quenching. They used information from published literature to calculate these emissions. This paper includes all of the calculations and assumptions used in these estimates. The references are also included. This study is a demonstration of a pilot effort to consider a new approach for estimating fugitive emissions from coke battery sources. The authors acknowledge that further effort from agencies and industry is required to fine tune this approach.
