Gas Composition Analysis
Gas Composition Analysis adalah analisis komposisi gas untuk mengetahui kandungan atau persentase berbagai jenis gas yang terdapat dalam suatu sampel gas.
Ruang Lingkup
Analisa komposisi gas meliputi identifikasi dan kuantifikasi hidrokarbon serta impurities dari Methane (C1) hingga Hexane (C6+) dan komponen berat (C7+). Parameter pengujian mencakup:
- Hidrokarbon ringan: Methane (C1), Ethane (C2), Propane (C3), Butane (C4), Pentane (C5), Hexane+ (C6+), C7+
- Non-hidrokarbon: Nitrogen, Oxygen, Carbon Dioxide, Carbon Monoxide
- Kontaminan: Hydrogen Sulfide (H₂S), Total Sulfur, Mercaptans, Mercury, Moisture
