도시가스품질검사기준 부취제 혼합비율문의

도시가스에 투입되는 부취제는 THT 70% ＋ TBM 30% 혼합하여 12~20mg/N㎥ 로 알고 있었읍니다   그런데 도시가스 품질검사기준고시(2012.2.8) 내용을보면 <TABLE style="BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; WIDTH: 373.95pt; BORDER-COLLAPSE: collapse; BORDER-TOP: medium none; BORDER-RIGHT: medium none; mso-yfti-tbllook: 1184; mso-border-alt: solid black .5pt; mso-border-themecolor: text1; mso-padding-alt: 0cm 5.4pt 0cm 5.4pt" border=1 cellSpacing=0 cellPadding=0 width=499 Table> <TBODY> <TR style="HEIGHT: 34.85pt; mso-yfti-irow: 0; mso-yfti-firstrow: yes"> <TD style="BORDER-BOTTOM: black 1pt solid; BORDER-LEFT: black 1pt solid; PADDING-BOTTOM: 0cm; BACKGROUND-COLOR: transparent; PADDING-LEFT: 5.4pt; WIDTH: 69.2pt; PADDING-RIGHT: 5.4pt; HEIGHT: 34.85pt; BORDER-TOP: black 1pt solid; BORDER-RIGHT: black 1pt solid; PADDING-TOP: 0cm; mso-border-alt: solid black .5pt; mso-border-themecolor: text1" width=92> 단   위</TD> <TD style="BORDER-BOTTOM: black 1pt solid; BORDER-LEFT: #ece9d8; PADDING-BOTTOM: 0cm; BACKGROUND-COLOR: transparent; PADDING-LEFT: 5.4pt; WIDTH: 8cm; PADDING-RIGHT: 5.4pt; HEIGHT: 34.85pt; BORDER-TOP: black 1pt solid; BORDER-RIGHT: black 1pt solid; PADDING-TOP: 0cm; mso-border-alt: solid black .5pt; mso-border-themecolor: text1; mso-border-left-alt: solid black .5pt; mso-border-left-themecolor: text1" width=302> 부취제 성분혼합</TD> <TD style="BORDER-BOTTOM: black 1pt solid; BORDER-LEFT: #ece9d8; PADDING-BOTTOM: 0cm; BACKGROUND-COLOR: transparent; PADDING-LEFT: 5.4pt; WIDTH: 77.95pt; PADDING-RIGHT: 5.4pt; HEIGHT: 34.85pt; BORDER-TOP: black 1pt solid; BORDER-RIGHT: black 1pt solid; PADDING-TOP: 0cm; mso-border-alt: solid black .5pt; mso-border-themecolor: text1; mso-border-left-alt: solid black .5pt; mso-border-left-themecolor: text1" width=104> 허용기준</TD></TR> <TR style="HEIGHT: 78.25pt; mso-yfti-irow: 1"> <TD style="BORDER-BOTTOM: black 1pt solid; BORDER-LEFT: black 1pt solid; PADDING-BOTTOM: 0cm; BACKGROUND-COLOR: transparent; PADDING-LEFT: 5.4pt; WIDTH: 69.2pt; PADDING-RIGHT: 5.4pt; HEIGHT: 78.25pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: black 1pt solid; PADDING-TOP: 0cm; mso-border-alt: solid black .5pt; mso-border-themecolor: text1; mso-border-top-alt: solid black .5pt; mso-border-top-themecolor: text1" rowSpan=2 width=92> mg/㎥ (0 ℃, 101.3 kPa)  </TD> <TD style="BORDER-BOTTOM: black 1pt solid; BORDER-LEFT: #ece9d8; PADDING-BOTTOM: 0cm; BACKGROUND-COLOR: transparent; PADDING-LEFT: 5.4pt; WIDTH: 8cm; PADDING-RIGHT: 5.4pt; HEIGHT: 78.25pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: black 1pt solid; PADDING-TOP: 0cm; mso-border-alt: solid black .5pt; mso-border-themecolor: text1; mso-border-left-alt: solid black .5pt; mso-border-left-themecolor: text1; mso-border-top-alt: solid black .5pt; mso-border-top-themecolor: text1; mso-border-bottom-themecolor: text1; mso-border-right-themecolor: text1" width=302> 첫번째 TBM (터셔리부틸머캡탄) 양파썩은냄새＋   THT (테트라하이드로티오펜)석탄가스냄새</TD> <TD style="BORDER-BOTTOM: black 1pt solid; BORDER-LEFT: #ece9d8; PADDING-BOTTOM: 0cm; BACKGROUND-COLOR: transparent; PADDING-LEFT: 5.4pt; WIDTH: 77.95pt; PADDING-RIGHT: 5.4pt; HEIGHT: 78.25pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: black 1pt solid; PADDING-TOP: 0cm; mso-border-alt: solid black .5pt; mso-border-themecolor: text1; mso-border-left-alt: solid black .5pt; mso-border-left-themecolor: text1; mso-border-top-alt: solid black .5pt; mso-border-top-themecolor: text1; mso-border-bottom-themecolor: text1; mso-border-right-themecolor: text1" width=104> 4~30 mg/㎥  </TD></TR> <TR style="HEIGHT: 112.7pt; mso-yfti-irow: 2; mso-yfti-lastrow: yes"> <TD style="BORDER-BOTTOM: black 1pt solid; BORDER-LEFT: #ece9d8; PADDING-BOTTOM: 0cm; BACKGROUND-COLOR: transparent; PADDING-LEFT: 5.4pt; WIDTH: 8cm; PADDING-RIGHT: 5.4pt; HEIGHT: 112.7pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: black 1pt solid; PADDING-TOP: 0cm; mso-border-alt: solid black .5pt; mso-border-themecolor: text1; mso-border-left-alt: solid black .5pt; mso-border-left-themecolor: text1; mso-border-top-alt: solid black .5pt; mso-border-top-themecolor: text1; mso-border-bottom-themecolor: text1; mso-border-right-themecolor: text1" width=302> 두번째 MES (황화메틸에틸)마늘냄새＋  DMS (황화이메틸)마늘냄새 ＋   TBM (터셔리부틸머캡탄) 양파썩은냄새＋     THT (테트라하이드로티오펜)석탄가스냄새  </TD> <TD style="BORDER-BOTTOM: black 1pt solid; BORDER-LEFT: #ece9d8; PADDING-BOTTOM: 0cm; BACKGROUND-COLOR: transparent; PADDING-LEFT: 5.4pt; WIDTH: 77.95pt; PADDING-RIGHT: 5.4pt; HEIGHT: 112.7pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: black 1pt solid; PADDING-TOP: 0cm; mso-border-alt: solid black .5pt; mso-border-themecolor: text1; mso-border-left-alt: solid black .5pt; mso-border-left-themecolor: text1; mso-border-top-alt: solid black .5pt; mso-border-top-themecolor: text1; mso-border-bottom-themecolor: text1; mso-border-right-themecolor: text1" width=104> 3~13 mg/㎥  </TD></TR></TBODY></TABLE>     질문 1. 표 첫번째 와 두번째 모두 투입되는지?

MES＋ DMS ＋TBM＋ THT의 경우에는  각 조성 비율은 정해져 있지 않습니다.  왜냐하면 LPG에는 다양한 부취제가 혼합되어 공급되기 때문입니다. 본 답변과 관련하여 추가로 문의사항이 있으신 경우 아래로 연락주시면 성심 성의껏 답변 드리겠습니다. <답변자 정보> * 답변자 : 김*구 / 소  속 : 품질검사부 /  연락처 : 031-310-1520  / 이메일 : navkyg@kgs.or.kr
