Flare Gas Recovery in Iraq: 6 Technologies That Can Turn Wasted Gas into Value

Across Iraq's oilfields, flare stacks burn day and night. They are a familiar sight, but they represent a serious technical and economic failure: valuable natural gas destroyed simply because there is nowhere for it to go.

The good news is that the technology to fix this already exists. Flare gas recovery is a mature field, with proven solutions ranging from simple compression systems to large-scale processing plants that feed refineries and petrochemical complexes. What Iraq needs is the investment to deploy these technologies at scale, and the engineering talent to operate them.

This guide explains six key technologies, how they apply to Iraq, and the skills professionals need to work with them. Engineers and managers building expertise in this area can explore Coventry Academy's Refinery and Petrochemical Training Courses.

Why Flare Gas Recovery Matters for Iraq

The scale of the challenge is significant. The World Bank found that global flaring grew for the third year in a row, reaching 167 billion cubic metres in 2025 and destroying gas worth about $54 billion. Iraq ranked with Russia and Iran as the largest flaring nations, with the three burning roughly 84 billion cubic metres between them, almost half the world's flared gas.

This creates a costly contradiction. Despite being OPEC's second-largest oil producer, Iraq has been a net importer of gas, flaring around half of its estimated 3.12 billion cubic feet per day of production until 2023. It has filled the gap by burning polluting liquid fuels in power stations and importing gas and electricity from Iran at high cost.

Flaring also carries a heavy environmental toll. Worldwide, it released an estimated 429 million tonnes of CO2-equivalent in 2025, including around 50 million tonnes of methane that escaped unburned.

6 Technologies for Flare Gas Recovery

No single solution fits every oilfield. The right technology depends on gas volume, composition, distance to markets and available infrastructure. These six options form the core toolkit.

1. Flare Gas Recovery Units (FGRUs)

What they do: Compressors capture low-pressure gas that would otherwise go to the flare header and route it back into the process or fuel gas system.

Best for: Reducing routine and continuous flaring at existing production facilities, refineries and petrochemical plants.

Key skills: Compressor operation and maintenance, liquid seal and flare system design, pressure control and safety interlocks.

2. Gas Gathering, Treatment and Pipeline Export

What they do: Networks of gathering lines collect gas from multiple fields, treatment plants remove water and acid gases, and pipelines deliver sales-quality gas to power stations and industry.

Best for: Large, clustered fields with steady gas volumes, as in southern Iraq.

Key skills: Dehydration (glycol units), amine sweetening, sulphur recovery, pipeline integrity and flow assurance.

3. NGL Recovery and Fractionation

What they do: Refrigeration or cryogenic turbo-expander processes separate natural gas liquids from the gas stream. Fractionation columns then split them into ethane, propane, butane and condensate.

Best for: Rich associated gas with high liquid content, which is common in Iraqi fields.

Key skills: Cryogenic process design, distillation column operation and troubleshooting, product specification control.

4. Gas-to-Power

What they do: Treated gas fuels gas turbines or engines to generate electricity, either at the oilfield or in large grid-connected power stations.

Best for: Areas with electricity shortages, or fields where power is needed to run oil production equipment.

Key skills: Gas turbine operation, fuel gas conditioning, combined-cycle efficiency and grid integration.

5. Gas Reinjection

What they do: Compressors inject gas back into the reservoir to maintain pressure, improve oil recovery or store gas for later use.

Best for: Fields where gas markets are not yet available but reservoir pressure support adds value.

Key skills: High-pressure compression, reservoir engineering and well integrity.

6. Gas-to-Chemicals and Small-Scale Conversion

What they do: Gas is converted into higher-value products such as methanol, ammonia, urea or olefins, or into compressed and liquefied gas for transport by truck or ship.

Best for: Building domestic petrochemical and fertiliser industries, or monetising gas at remote sites far from pipelines.

Key skills: Reaction engineering, catalyst management, steam cracking and petrochemical plant operations.

Technology in Action: Iraq's Flagship Projects

Several of these technologies are already working in southern Iraq.

Basrah Gas Company combines gathering, treatment, NGL recovery and export. Operating since 2013, it runs compressor stations, processing plants, a pipeline network and a storage and marine export terminal. It supplies dry gas to Iraq's grid and produces LPG and condensate. Its BNGL expansion adds two 200 mmscf/d processing trains, raising capacity to 1.4 bcf/d, and the company says this will increase its emissions reduction capability by about 10 million tonnes a year.

TotalEnergies' Gas Growth Integrated Project (GGIP) pairs gas-to-power with renewables. It includes recovering flared gas from three southern fields for power plants, alongside Ratawi field redevelopment, a 1 GWac solar farm and a seawater treatment plant. Its gas midstream plant, awarded to China Petroleum Pipeline Engineering in 2025, is designed to process 300 Mcf/d. Once running, it is expected to fuel about 1.5 GW of generation, powering roughly 1.5 million homes.

These projects demonstrate that flare gas recovery is technically proven in Iraqi conditions. The next step is extending it to fields not yet connected. BGC, for example, currently takes raw gas from only three large fields: Rumaila, Zubair and West Qurna 1.

Choosing the Right Technology: Key Questions

Engineers and project teams typically evaluate:

1. How much gas is flared, and how steady is the flow? Accurate metering is the essential first step.
2. What is the gas composition? Sour or liquid-rich gas needs more treatment but offers more valuable products.
3. How far is the nearest market? Distance to pipelines, power plants or refineries shapes the economics.
4. What infrastructure already exists? Tying into existing systems often cuts cost and time.
5. What are the commercial terms? Gas pricing and offtake agreements determine investment viability.
6. Does the organisation have the skills to operate it? Advanced plants need advanced teams.

The Skills Behind the Technology

Every technology described above depends on skilled people. Iraq's growing gas sector will need:

• Process engineers to design, simulate and optimise gas and refinery units
• Operations teams to run compressors, columns and treatment units safely and efficiently
• Mechanical and reliability engineers to keep rotating equipment and heat exchangers available
• Instrumentation and control specialists to manage automation and safety systems
• Process safety professionals to control the hazards of high-pressure, flammable and toxic streams
• Project managers to deliver complex facilities on schedule and budget

The workforce demand is real. GGIP construction alone was expected to employ 7,000 Iraqi nationals, and each facility will need trained operators and engineers long after construction ends.
