Abstract
공장내 설치되어 있는 수천개의 비산배출원으로부터 배출되는 VOCs의 양을 산정하기 위해서는 많은 비용과 시간이 소요된다. 이러한 노력을 줄이기 위하여 전산모사방법을 이용하여 배출량을 예측하는 방법을 제시하였다. 예측된 값의 검증을 위하여 밸브, 플랜지 등의 비산배출원으로 구성되어 있는 실험장치를 고안하고 내부를 흐르는 유체의 종류 및 조건에 따른 배출량을 백포집법에 의해 샘플링하여 GC로분석한 후, 분석된 데이터를 전산모사를 통해 얻은 결과와 비교하였다. 그 결과, 전산모사를 이용하여 밸브, 플랜지, 개방식라인으로부터 배출되는 벤젠과 톨루엔의 양을 예측할 수 있었다.
Considerable effort and expense have been devoted to the estimation and acquisition of the amounts of VOCs released from thousands of the fugitive emission sources installed in chemical processes. In order to reduce the effort required on the estimation of VOC release, a methodology using a computational fluid dynamics (CFD) was proposed. The estimated values were compared with the experimental data obtained using a designed experimental apparatus that was composed of fugitive emission sources such as valves, pump, and flange. The emissions were sampled in sampling tedlar bags for a variety of volatile compounds at different pressures. The components were analyzed by a portable gas chromatograph. In conclusion, the amounts of benzene and toluene released from fugitive emission sources could be successfully estimated using the CFD technique.
