Penentuan Komposisi Hidrokarbon pada LNG yang Terdapat dalam Berth II dan Berth III dengan Menggunakan Kromatografi Gas

Abstract

LNG (Liquified Natural Gas) is a melted natural gas. LNG have to be saved at ± -160oC. The composition of LNG is hydrocarbon alcana such as methane ± 92 %, ethane ± 5 %, Prophane ± 1.5 %, Buthane ± 0.2 %, Penthane ± 0.01 %, and a little nitrogen ± 0.1 %, to recognize how much concentrate in each component, the sampel of LNG will analys hydrocarbon and nitrogen by using gas cromatography, after detecting the concentrate in each component, so HHV can be counted from LNG, because HHV can determine LNG cost in the marked world. One of HHV grade in LNG is methane ± 92 %, Ethane ± 5 %, Prophane ± 1.5 %, Iso buthane ± 0.2 %, normal buthane ± 0.2 %, iso penthane ± 0.01 %, and normal penthane ± 0.004 %.
