Abstract

According to domestic air pollutant emission statistics, a considerable amount of air pollutants is generated by ships. Therefore, various policies are being implemented to limit air pollutant emissions from ships and improve the air quality in ports. In addition, international conventions are carried out for the prevention of marine pollution by ships. However, because few studies and experiments have been conducted on the measurement of air pollutants emitted from actually operating ships, this study presented a method and possibility for evaluating air pollutant emissions from a 9,196GT ship actually operating using a portable emission measurement system (PEMS). A difference in emission occurred depending on the RPM and load, and the emission of NOX was 497-2,060ppm, CO2 was 1.55-6.9%, and CO was 0.002-0.14%. The emission specified in the shop test provided by the engine manufacturer differed from the actual emission measured. This study proved that the maximum emission of each air pollutant generated in the entire sailing section of the ship was included in the PEMS measurement range, and the possibility of using PEMS for ships within 10,000GT was verified.

국내 대기오염물질 배출량 통계에 따르면 상당한 대기오염물질이 선박에 의해 발생하고 있다. 따라서 선박으로부터의 대기오염물질 배출 제한과 항만지역 대기질 개선을 위해 다양한 정책들이 시행되고 있고, 국제적으로도 선박에 의한 해양오염 방지를 위해 국제 협약 등이 이루어지고 있다. 하지만 실제 운항하는 선박에서 배출되는 대기오염물질 측정에 관한 연구와 실험은 거의 이루어지고 있지 않아, 본 연구는 이동식배출가스측정장비(PEMS)를 사용하여 실제 운항하는 9,169톤급 선박에서 발생하는 대기오염물질 배출량 평가에 대한 방법과 가능성을 제시하였다. RPM과 부하에 따라 배출량의 차이가 있었으며, NOX 배출량은 497-2,060ppm, CO2는 1.55-6.9%, CO는 0.002-0.14% 수준이다. 엔진 제조사에서 제공하는 Shop Test에 명시된 배출량과 실제 측정된 배출량에 차이가 있음을 확인하였다. 대상선박의 전 항해구간에서 발생하는 각 대기오염물질 최대 배출량이 PEMS 측정 구간에 포함되는 것을 확인하여, 총톤수 10,000톤급 이내 선박에 PEMS 활용 가능성을 검증하였다.
