초록

국내에서 유통되고 있는 LPG중의 잔류물질을 분석하였다. 시료 채취 장소는 LPG용기 재검사장의 용기 2곳, LPG집단공급시설 기화기 6곳 및 LPG충전소의 압축기 오일 1곳이었다. LPG용기재검사장의 용기내 잔류물질의 성분은 alkene, diene계통의 물질(탄산소$\leq$9), 방향족 탄화수소와 타르성 화학물질 (탄소수$\geq$10)으로서 각가 1.5∼39.9%, 0.7%, 57.8∼96.0%이었다. 반면에 LPG집단공급시설의 잔류물질 및 LPG 충전소 오일 중의 타르성 화학물질은 96.6%이상이었다. 채취한 9가지 시료는 3가지 군집으로 분류되었다. SE사 용기 재검사장 시료 (SE사 시료와 S사 LPG 용기 재검사장 시료와의 유클리디안 RMS 거리=2.11), S사 LPG용기재검사장 시료 (집단공급시설시료 군과의 유클리디안 RMS거리=0.110), 집단공급시설 시료군(유클리디안 RMS거리〈0.075)이다. LPG 집단공급시설 시료의 성분이 LPG충전소 압축기오일의 조성과 매우 유사하고, 충전소 오일의 밀도와 집단공급시설의 시료 밀도가 각각 0.873, 0.873 $\pm$0.00798 (99% 신뢰구간)인 것으로 보아 타르성 화학물질은 LPG유통과정의 압축기 오일로부터 유입한 것으로 추정한다

The composition of trace materials in domestic circulated LPG are determined. The sampling points are two cylinders of LPG cylinder re-inspection center, six vaporizer of LPG-supplying group facilities, and the compressed oil from one LPG station. In the trace materials from cylinder of LPG cylinder-reinspection center, alkene and diene derivative (No. of carbon ${\leq}9),$ aromatic compounds, and tarry chemicals(No. of carbon ${\geq}10)$ are 1.5~39.9%, 0.7%, 57.8~96.0%, respectively. While in the trace materials from LPG-supplying group facilities and in the oil from LPG station, tarry chemicals(No. of carbon>10) exceed 96.6%. Nine samples are classified into three clusters. One cluster is the sample of SE company cylinder-reinspection center(Euclidian distance between S company LPG cylinder-reinspection center and SE company cylinder-reinspection center=2.11), the other is the sample of SE company LPG cylinder-reinspection center(Euclidian distance between from samples of LPG-supplying group facilities including compressed oil from LPG station=0.110) the third is the samples of LPG-supplying group facilities(Euclidian distances among them<0.075). The compositions of samples from LPG-supplying group facilities are similar to those of oil from LPG station. Furthermore densities of samples from LPG-supplying group facilities and compressed oil in LPG station are 0.873, 0.873 [0.00798 (99% confidence limits) respectively. It was presumed that tarry chemicals had been leached from the compressed oil of LPG supplying facilities.
