Associated Petroleum Gas Generator Set
Spark-ignition gas engine generator configured for associated petroleum gas (APG) recovered at oil production sites, with integrated gas treatment, engine, alternator, and control panel for on-site power generation where flaring reduction and lease power supply are required.
Product Introduction
The Associated Petroleum Gas Generator Set is a spark-ignition gas engine generator configured to operate on associated petroleum gas produced as a byproduct of crude oil extraction. Associated gas typically contains methane, heavier hydrocarbons including propane, butane, and pentane, along with variable concentrations of hydrogen sulfide, carbon dioxide, nitrogen, and water vapor, depending on the reservoir and separation stage. The set integrates a gas treatment train for knock control, moisture removal, particulate filtration, and pressure regulation upstream of the engine, followed by the gas engine, alternator, cooling system, and control panel assembled as an integrated unit. Power output ranges from 200 kW to 4,000 kW, with engine speed set at 1500 rpm for 50 Hz or 1800 rpm for 60 Hz output. The control panel manages engine start and stop, gas supply regulation, alternator excitation, synchronization, and protection functions. The set is applied at oil production sites and lease facilities where captured associated gas is converted to electricity for on-site operations or export, reducing flaring volumes and offsetting diesel or grid power purchases.
Core Advantages for B2B Operations
Heavy Hydrocarbon Knock Control
Associated gas contains propane, butane, and heavier fractions that raise the fuel's knock tendency compared with dry natural gas. Engines configured for APG service include combustion chamber geometry and ignition timing strategies that accommodate higher knock propensity, along with knock sensors and automatic timing adjustment to protect the engine across varying gas composition.
Gas Composition Tolerance
Associated gas composition varies as the field matures and as separation conditions change. The gas treatment train and air-fuel control system are configured to handle a range of methane numbers and heating values, with real-time monitoring of gas properties and automatic adjustment of the fuel-air mixture to maintain stable combustion.
Flare Reduction and Emissions Compliance
Associated gas that would otherwise be flared can be routed to the generator set for combustion and power generation. This reduces flare volumes and associated emissions, supporting operators in meeting flaring reduction targets and regulatory obligations for gas utilization at the lease site level.
Remote and Unattended Operation
Oilfield lease sites are often located in remote areas without permanent operating staff. Control panels can be configured with remote monitoring interfaces and automatic start and stop functions, allowing the generator set to operate unattended and to be supervised from a central control room or mobile terminal.
Diesel Displacement at Remote Sites
Power at remote oilfield sites is commonly supplied by diesel generator sets with fuel transported by truck. Operating on associated gas available at the wellhead or separation facility reduces diesel consumption, fuel logistics, and the associated cost per kilowatt-hour generated on site.
Modular Deployment for Field Development
Generator sets can be delivered in containerized or skid-mounted configurations for transport and commissioning at lease sites with limited infrastructure. Additional units can be added as field production grows, allowing capacity to be matched to gas availability over the life of the field.
