밸브 및 플랜지의 누출오염원 유해대기오염물질 모니터링방법 개발과 적용

Blow-through bag method was developed to estimate emission amount of the hazardous air pollutants on the fugitive emission sources. This method has modified the related US-EPA method to improve the detecting accuracy and sampling efficiency for the valves and flanges of the fugitive emission sources. This developed method shortens the sampling time above 48% and improves 60 times of detection limits in comparison with the related US-EPA method. Therefore this method should facilitate more rapid and precise estimation of fugitive emission amount. We figured out fugitive emission and total emission amount and examined its efficiency with this developed method from fugitive emission sources on site. This Blow-though bag method was significantly improved the problems about sampling time and detection limit. Accordingly, the method enabled us to calculate a precise air emission amount of hazardous air pollutants for the industrial fugitive emission sources.
