What Is Associated Gas?

関連ガス, 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
石油・ガス	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

⚙️ Why Use a Dedicated Associated Gas Compressor?

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 関連ガス圧縮機 offers the following advantages:

✅ Handles multi-component gas streams
✅ Designed for variable pressure and flow
✅ Ensures leak-free, oil-free compression
✅ Supports high ambient そして 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 随伴ガス 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 そして 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 & Demanding

The 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そして lubrication safety.

Keepwin’s Solution: Model 2VF-3.6/5-400

To meet these technical demands, キープウィンテクノロジー河北有限公司 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) への 40 MPa (g).
