Pengaruh Spesifik Grafity ( SG ), Gross Heating Value ( GHV ) DAN C6+ terhadap Mutu Gas Alam di PT Pertamina EP Region Sumatera Field Pangkalan Susu

Abstract

The component of Natural gas commonly consisted of hidrocarbon like metane, etane, propane, butane, pentane, and C6 + or Heksane.Commomly, the quality of natural gas was influenced by many factor. Some of them were Spesific Gravity ( SG ), Gross Heating Value ( GHV ), and hydrocarbon content ( C6 + ). The Advantage of these factor depending on the locations of gas fields. With the Analysis by Gas Chromatography, we can determine Spesific Gravity ( SG ), Gross Heating Value ( GHV ), and hydrocarbon content ( C6 + ). The increase of Spesific Gravity ( SG ) and Gross Heating Value ( GHV ) value, the quality of natural gas also increase. Hidrocarbon content ( C6 + ) caused the significant influence because there was only a few in the natural gas. Commonly, value of Gross Heating Value ( GHV ), and hydrocarbon content ( C6 + ) in natural gas each 950 – 1300 BTU cft, C6 + adalah 0,07 %.
