The Flaring ProblemUtilization Possibilities

• 108 billion cubic meters of associated gas are
  flared and vented annually.
• This contributes to global emissions of 300
  million tons of carbon dioxide equivalents (CO2e)
• Options for flaring reduction
• Gas reinjection
• Commercial use (liquefaction)
• On-site power generation.
• 108 billion cubic meter associated gas are equal
  to 125,000 MW of gas power p.a.
• If utilized in gas engines, 53,000 MW electricity
  p.a. could be generated.

PGI Engine Performance Gas Injection

• PGI the gas engine without spark plugs
• High power output comparable to diesel engines
• Highest thermal efficiency combined with
  extremely low emissions (low NOX, low SOX and low
  CO2)
• Ignition of pilot fuel at a hot surface inside
  prechamber. Low maintenance costs due to PGI
  concept Ignition system without spark plugs
• Gas flexibility

Dual-Fuel Engine 32/40DF, 51/60DF

• 32/40 DF 51/60 DF
• Fuel flexibility due to possible liquid-fuel
  (MDO, HFO, crude) and gaseous-fuel (natural gas,
  flare gas) operation.
• Automatic, uninterrupted switch over from gas to
  diesel fuel operation and vice versa.
• High efficiency and reliability.
• High specific engine rating up to 1000kW/Cly.
• 16/24
• Originally developed for LPG market.
• Mixture of liquid (MDO, HFO, crude) and gaseous
  (natural gas, flare gas) fuels.
• Special technology for low quality gases (MN lt
  60, high content of heavy hydrogen carbonates,
  low heat value).
• Wide range of engine operations
