Example
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 < 60, high content of heavy hydrogen carbonates, low heat value).
– Wide range of engine operations

Summary Onsite Power Generation Utilizing Flare Gas
• Highest reliability: Engines are built for 8000+ operating hours per year.
• Engines offer best efficiency ratio for on-site power generation.
• Providing electricity for the oil bore fields in remote areas or for local grids.
• Dual-fuel engines offer high fuel flexibility.
• PGI gas engine technology offers best efficiency and lowest emissions.
• Different site conditions, e.g. gas quality, quantity and power demand, require project specific solutions.
