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

Example

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
