Associated gas, also known as flare gas or casinghead gas, is a natural byproduct of crude oil extraction. When oil is brought to the surface, natural gas dissolved in the oil is also released. In many cases, this gas is flared—burned off—due to lack of infrastructure or processing capability.
However, with proper gas compression and recovery, associated gas can be transformed from waste into a valuable fuel or feedstock, supporting energy sustainability goals and regulatory compliance.

Associated gas, once compressed and treated, finds application in various industries:
| Application Area | Use Case Example |
|---|---|
| Petrolio e gas | Reinjection, gas lift, flare gas recovery |
| Power Generation | On-site gas engines or turbines |
| Petrochemical | Feedstock for hydrogen or syngas production |
| CNG / LNG Systems | Conversion into compressed/liquefied gas |
| Environmental Compliance | Flare minimization and carbon footprint reduction |
Associated gas contains a complex mix of hydrocarbons—such as methane, ethane, propane, butane, pentane—as well as non-hydrocarbon impurities like CO₂, nitrogen, H₂S, and helium.
A purpose-built compressore di gas associato offers the following advantages:
✅ Handles multi-component gas streams
✅ Designed for variable pressure and flow
✅ Ensures leak-free, oil-free compression
✅ Supports high ambient e remote field operation
✅ Enables energy recovery from flare gas
In the oilfields of southeastern Turkey, one upstream energy company faced a recurring issue: large volumes of associated gas were being flared due to insufficient compression infrastructure. This not only caused environmental penalties but also wasted valuable energy resources.
The customer’s goal was to recover and compress this flare gas—rich in hydrocarbons—for on-site power generation e gas reinjection.
To achieve this, they required a highly customized compressor solution capable of handling complex gas compositions at extreme discharge pressures up to 40 MPa (400 bar).
Gas Composition: Complex & DemandingThe associated gas in this project was a typical multicomponent hydrocarbon stream, primarily consisting of:
Methane (CH₄): 73.01%
Ethane (C₂H₆): 9.9%
Propane (C₃H₈): 9.2%
Butanes, Pentanes, Hexanes (C₄–C₆): ~4%
Nitrogen (N₂): 0.96%
Trace Oxygen (O₂ < 0.005%)
This mixture presented unique challenges in terms of volatility, pressure management, e lubrication safety.
Keepwin’s Solution: Model 2VF-3.6/5-400To meet these technical demands, Keepwin Technology Hebei Co., Ltd. delivered a fully customized double V-type 5-stage air-cooled reciprocating compressor, model 2VF-3.6/5-400, capable of compressing gas from 0.5 MPa (g) to 40 MPa (g).
