Where does the gas come from ?
Image Legend1. Salt cavern hydrocarbon storage2. Oil and gas reservoir3. Natural gas reservoir storage4. Transmission pipeline5. Compressor6. Gathering pipeline7. Emergency shut down valve
PII Training - Gas Processing
How it differs with other fossil fuels ?
Natural Gas C/H Ratio:
- CH4 : 0.25
- C3H8 : 0.375
- C10H22 : 0.454
- C6H6 : 1

Process Types in Natural Gas Processing
• Purification– From other phases (liquids, solids)– From impurities
• CO2
• H2S• H2O• Mercaptans (R-SH)• Carbonyl Sulfide (COS)• Carbon Disulfide (CS2)• Mercury (Hg)
• Fractionation– Lean Gas– NGLs– Condensate
• Liquefaction (LNG)
