Gas Treatment Market Size and Forecast, 2025-2035 (USD Billion)

Amines held the largest share of the market in 2025, accounting for 72.60%. This is because amine units are widely used to remove acid gases in gas processing plants, refineries, and LNG facilities. Asia Pacific held 31.40% of the market revenue in 2025, supported by gas processing, refining, and LNG import facilities in China, India, Australia, and Southeast Asia.

The market is growing because natural gas and LNG production are increasing, more sour gas fields are being developed in the Middle East, and rules on sulphur and emissions are becoming stricter. Amine solvents are also being used in carbon capture projects. Chemical companies are introducing advanced amine technologies for carbon capture and developing selective solvents that can reduce energy use.

The gas treatment market is expected to grow from USD 5.24 billion in 2025 to USD 9.04 billion by 2035. This growth is mainly due to the rising need to treat natural gas, including sour gas that contains high levels of H2S and CO2. LNG plants, refineries, and new carbon capture facilities also need amine solvents to remove unwanted gases.

More companies are choosing selective and energy-efficient formulated amines instead of standard solvents. These products can improve performance and reduce energy use, adding value to the market. As a result, the market is expected to reach USD 6.88 billion by 2030 and grow at a CAGR of 5.60% from 2026 to 2035.

• Analyst View: We estimated the market by looking at the amount of gas treated in natural gas processing plants, LNG facilities, refineries, chemical plants, and carbon capture projects. We then considered the amount of acid gas removed, the quantity of solvents and other chemicals used, and their average prices.

Gas volumes were based on production levels, LNG capacity, and refinery output. Chemical use was estimated by considering solvent losses, chemical breakdown, and the amount of scavengers needed for different applications.

We cross-checked the results against gas treatment chemical revenue from leading amine producers and oilfield chemical suppliers, as well as published market estimates. This process placed our base-year estimate slightly above comparable figures. The expected growth reflects higher gas and LNG production and rising demand from carbon capture projects, while improvements in solvent efficiency may limit some of the growth.

Market Trends

• Selective amines are helping reduce energy use in sulphur recovery.
• Amine solvents are increasingly being used in carbon capture projects.
• The development of sour gas fields is increasing the need to remove H2S.
• LNG plants need gas with very low CO2 levels before liquefaction.
• Non-regenerable scavengers are used at wellheads and in smaller gas streams.
• Solvent recovery and cleaning help reduce amine losses.

Drivers, Restraints and Opportunities

Driver

Natural gas and LNG production continue to increase, creating a greater need to remove H2S, CO2, and water from gas. Sour gas fields in the Middle East require large units to remove acid gases. Carbon capture projects also use amine solvents to capture CO2 from flue gas.

Restraint

More efficient solvents and solvent recovery systems can reduce the amount of new chemicals needed. Changes in gas prices can also affect investment in gas processing facilities. In addition, carbon capture projects may face delays or depend on government support and subsidies.

Opportunity

Carbon capture projects at power plants, cement plants and waste-to-energy facilities could create new demand for solvents. Selective amines can also help refineries and gas processing plants increase capacity without building new units. LNG expansion in the Middle East, North America and Africa is expected to create demand for large gas treatment facilities.

Research Methodology

The gas treatment market includes amine and non-amine chemicals used to treat natural gas, LNG feed gas, refinery gas, syngas, and flue gas around the world.

The 2025 base-year estimate was developed by calculating the amount of gas treated, the quantity of acid gases removed, the amount of solvents and other chemicals used, and their prices. The estimate was then checked against gas treatment chemical revenue from leading amine producers and oilfield chemical suppliers.

Market values for each segment, region and company were estimated based on chemical type, application, end use and regional gas processing capacity. Key estimates were checked against company disclosures, regulatory and industry data, and published estimates from other sources. Inputs that could not be matched or confirmed were excluded.

All segment, regional and company figures were aligned with the same 2025 base year. The forecasts for 2026–2035 were then recalculated using a constant CAGR from the 2025 base and checked for consistency.

Analyst View Overall Market

The gas treatment market is expected to grow as natural gas production, LNG activity, and refining increase. Carbon capture is also becoming a new source of demand for amine solvents.

Our estimate connects market demand with the amount of gas treated, the level of acid gases present, and the prices of treatment chemicals. This means the forecast depends mainly on gas production and the development of carbon capture projects.

The main growth opportunities come from sour gas projects, LNG expansion, and carbon capture. However, improvements in solvent efficiency and delays to projects could limit market growth.
