China's ultra-low-emission program targets 80% of national cement clinker production capacity for completion of the required transformation by 2028, supporting demand for particulate, SOx and NOx control equipment.• Chemical, refining and petrochemical facilities will continue to require scrubbers, absorbers, VOC-control systems, thermal and catalytic oxidizers, flare gas management and continuous emissions monitoring.

Retrofit and replacement demand is expected to remain significant as older facilities upgrade equipment to meet increasingly stringent emission performance requirements. Policies• China's Ministry of Ecology and Environment has established increasingly stringent industrial emission requirements through national air-pollution standards, pollution discharge permits and sector specific ultra-low-emission programs.• The steel industry's ultra-low-emission framework covers both organized and fugitive emissions, encouraging investment in dust collection, enclosed material handling, desulfurization, denitrification and continuous emissions monitoring systems.• China introduced HJ 1408-2024, a technical specification for ultra-low-emission treatment of sintering exhaust gas in the steel industry. The standard became effective on April 1, 2025 and establishes requirements for the design, construction, acceptance and operation of treatment projects.• For cement plants, China's ultra-low-emission framework establishes stringent emission limits, including 10 mg/m³ for particulate matter, 35 mg/m³ for SO₂ and 50 mg/m³ for NOx for cement kilns and waste-heat utilization systems under the specified reference conditions.• China also expanded its national carbon emissions trading system in March 2025 to include steel, cement and aluminum smelting. This strengthens the connection between industrial energy efficiency, carbon reduction and environmental technology investment.Industry News• More than 95% of China's coal-fired power plants had undergone ultra-low-emission upgrades, while approximately 45% of crude steel capacity had undergone such upgrades according to China's Ministry of Ecology and Environment.• By June 2025, approximately 590 million tonnes of crude-steel capacity had completed full-process ultra-low-emission transformation, while another 360 million tonnes had completed key-process upgrades. Together, these facilities represented more than 80% of China's total crude-steel capacity.• China's steel sector ultra-low-emission transformation has reportedly reduced atmospheric pollutant emissions from the industry by approximately 60% and generated more than CNY 600 billion in associated investment.• China produced approximately 2.13 billion tonnes of cement in 2022, representing around 57% of global cement production, while coke production reached approximately 470 million tonnes, equivalent to around 70% of global production.Industry News• In April 2025, HJ 1408-2024 entered into force, establishing a dedicated technical specification for ultra-low-emission treatment engineering for steel sintering exhaust gas. This is expected to support further investment in particulate, SOx and NOx treatment systems.• In June 2025, China announced nationwide implementation measures for ultra-low-emission transformation in the cement and coking industries. The cement program targets 80% of national clinker capacity for completion by 2028, creating a sustained opportunity for gas-cleaning equipment suppliers.• In July 2025, China's Ministry of Ecology and Environment indicated that further strengthening of ultra-low-emission requirements for the steel industry would be pursued, including research toward upgrading existing requirements into mandatory standards.• China's gas-cleaning technology market is increasingly shifting from basic pollution control installations toward integrated multi pollutant control, high-efficiency filtration, digital emissions monitoring and energy efficient retrofit solutions, particularly across steel, cement, chemicals, refining and other heavy industries.Segment AnalysisChina Gas Cleaning Technologies Market By Technology• Particulate control represents a major technology segment in the China gas cleaning technologies market, supported by the country's large steel, cement, chemicals, non-ferrous metals, power generation, mining, and manufacturing industries.

Baghouse filters, electrostatic precipitators, wet electrostatic precipitators, cyclones, cartridge filters, and other dust-collection systems are widely used to control particulate emissions. China's air-pollution regulations require major coal-fired and industrial facilities to install or upgrade dust-removal systems, while national policies continue to promote high-efficiency particulate-control technologies. • Gas scrubbing is an important technology segment in China because industrial facilities generate SOx, HCl, HF, ammonia, and other soluble or acidic gases. Wet scrubbers, limestone-gypsum systems, dry and semi-dry scrubbers, alkaline scrubbers, and other absorption technologies are used across power, cement, chemicals, metals, refining, and waste-treatment facilities. China's industrial pollution-control policies specifically promote desulfurization and other flue-gas treatment technologies, while industrial furnace requirements identify high-efficiency desulfurization systems for several major industries. China Gas Cleaning Technologies Market By End-Use• Power represents a major end-use sector for gas cleaning technologies in China because of the country's extensive thermal power and industrial boiler infrastructure. Particulate collectors, flue-gas desulfurization systems, NOx-control technologies, and continuous emissions-monitoring systems are used to control combustion emissions. China's Air Pollution Prevention and Control Law requires coal-fired power plants and other coal-consuming facilities to install dust removal, desulfurization, and denitrification systems or implement equivalent technological upgrades.• Cement is one of the key end-use industries for gas cleaning technologies in China because clinker production, kiln combustion, grinding, crushing, material handling, and drying generate particulate matter, NOx, SOx, and other pollutants.

Baghouse filters, electrostatic precipitators, scrubbers, SNCR, SCR, and low-NOx combustion technologies are widely relevant to cement plants. China's cement-sector ultra-low-emission requirements target particulate matter, SO2, and NOx and require comprehensive treatment across major production and dust-generating processes. A revised cement emission-standard amendment is scheduled to take effect for new enterprises from April 1, 2026, with specified requirements for existing enterprises subsequently applying. China Gas Cleaning Technologies Market By System• New installation systems represent an important portion of the China gas cleaning technologies market, particularly for new chemical plants, steel and cement facilities, industrial projects, waste-treatment infrastructure, power facilities, and manufacturing capacity additions. New systems are designed according to plant capacity, process characteristics, pollutant profiles, and applicable national and local emission requirements. China's pollution control framework increasingly emphasizes the integration of high-efficiency dust removal, desulfurization, denitrification, VOC treatment, and monitoring technologies into new and expanded industrial facilities. • Retrofit/replacement systems account for a substantial share of demand because China has a very large installed base of power plants, steel mills, cement plants, chemical facilities, refineries, glass plants, and other industrial assets. Existing gas cleaning systems are upgraded or replaced to achieve tighter emission limits, improve removal efficiency, accommodate production changes, and comply with ultra-low-emission programs.

China's ongoing ultra-low-emission transformation of steel, cement, industrial furnaces, and other high emitting industries creates significant opportunities for retrofit and replacement systems.Considered in this report• Historic Year: 2020• Base year: 2025• Estimated year: 2026• Forecast year: 2031Aspects covered in this report• Gas Cleaning Technologies Market with its value and forecast along with its segments• Various drivers and challenges• On-going trends and developments• Top profiled companies• Strategic recommendationBy Technology• Particulate Control• Gas Scrubbing• NOx Control• VOC/Organic Gas Control• Fine Particle/Mist ControlBy End-Use• Power• Cement• Metals & Steel• Chemicals• Refining & Petrochemicals• Mining• Pulp & Paper• OthersBy System• New Installation• Retrofit/Replacement• Aftermarket/Services.
