Sulfuryl Fluoride Fumigant Industry Chain Analysis
Process Flow of Sulfuryl Fluoride:
（1）Catalytic Reaction
Liquid SO₂, Cl₂, and anhydrous HF are vaporized by heating and then fed into a raw material gas dryer to remove trace moisture. The dried gases enter a fixed-bed reactor containing a catalyst, where a gas-phase fluorination reaction occurs, producing sulfuryl fluoride (SO₂F₂), HCl, and a byproduct (SO₂FCl). A small amount of CO₂ is generated due to the high-temperature activity of the activated carbon catalyst. The catalyst used for the fluorination reaction is activated carbon.
（2）HF Recovery
The hot gaseous products from the fluorination reaction pass through a condenser for HF recovery. About 95% of the unreacted HF is condensed and returned to the reactor. The uncondensed HF enters the next acid gas absorption step together with the gaseous materials.
（3）Acid Gas Absorption
Gaseous materials pass through a graphite falling-film absorption tower to absorb the byproduct HCl. The absorption solution obtained is byproduct hydrochloric acid. After acid gas absorption, the gas enters a water-washing tower and a gas-liquid separation tower.
（4）Water Washing and Gas-Liquid Separation
The gas from acid gas absorption enters a water-washing tower, where water spray removes residual acidic gases such as SO₂. To improve washing efficiency, two reagents (#1 and #2 containing NH₄⁺ alkaline substances) are added. A large amount of water is used, and a circulating washing method is adopted. The wash water is treated as wastewater. After washing, the gaseous materials undergo gas-liquid separation to remove all moisture. During the graphite absorption and water-washing processes, some SO₂F₂ and intermediate SO₂FCl are absorbed and hydrolyzed, producing H₂SO₄ and HCl, which enter the byproduct hydrochloric acid and wastewater streams.
（5）Drying
The water-washed sulfuryl fluoride gas enters a gas storage tank. In the tank, the gas undergoes gas-liquid separation and dehydration, followed by condensation and molecular sieve drying, producing crude liquid sulfuryl fluoride.
（6）Distillation
The dehydrated crude sulfuryl fluoride is sent to a distillation column for further purification. Non-condensable gases such as CO₂ are discharged from the top, carrying a minimal amount of sulfuryl fluoride. Purified sulfuryl fluoride is collected from the bottom, dehydrated again, stored in finished product tanks, and then packaged for sale.
Key Trends
Expansion of Sulfuryl Fluoride Applications and Emerging Market Potential
Sulfuryl fluoride, as a multi-purpose fumigant, is gradually expanding its applications from traditional areas such as sanitation, grain storage, ship holds, containers, tobacco, soil, and cultural relics fumigation to emerging sectors including new materials and renewable energy industries. In these high-end materials and renewable energy fields, sulfuryl fluoride primarily serves as a chemical raw material for the production of functional materials and high-performance chemicals, demonstrating its cross-industry application potential.
In the lithium battery electrolyte sector, sulfuryl fluoride can be used as a precursor to produce lithium bis(fluorosulfonyl)imide (LiFSI). Fushine Pharmaceutical Co., Ltd. in China has developed large-scale production technology for this process, offering advantages over traditional methods such as lower production costs, environmental friendliness, and suitability for industrial-scale manufacturing. LiFSI features high conductivity, chemical stability, and thermal stability, addressing the shortcomings of lithium hexafluorophosphate (LiPF₆) in high-performance lithium batteries and meeting demands for wide-temperature, high-safety applications. This indicates a broad market prospect for sulfuryl fluoride in high-end electrolyte materials.
Meanwhile, Linhai Limin Chemicals Co., Ltd. is actively expanding into the renewable energy battery value chain. By acquiring land and planning to construct projects producing 10,000 tons of lithium battery electrolytes and 12,000 tons of sulfuryl fluoride annually, the company demonstrates the strategic value of sulfuryl fluoride in new energy materials production. The project also includes R22 and related infrastructure, indicating an effort to enhance core competitiveness through vertical integration, enabling scale economies and rapid growth.
Overall, the sulfuryl fluoride market is transitioning from a traditional fumigant to a high-end industrial raw material. This cross-industry application not only broadens the market space but also increases its added value, particularly in emerging industries such as renewable energy, aerospace, and water treatment membrane materials.
Continued Growth in Sulfuryl Fluoride Use and Emissions
Sulfuryl fluoride, as a replacement fumigant for methyl bromide, continues to see growing use in structural and soil fumigation, as well as post-harvest food treatments. Usage is especially concentrated in California, Japan, and major global agricultural regions including Canada, Western Europe, Mexico, Indonesia, and Thailand. Although sulfuryl fluoride does not directly deplete stratospheric ozone, it is a potent greenhouse gas with a 100-year global warming potential (GWP) of approximately 4780 and an atmospheric lifetime of 36 ± 11 years.
Research by A. Gressent et al. shows that the global molar fraction of SO₂F₂ increased from 0.3 ppt in 1978 to 2.5 ppt in 2019, while emissions rose from 0.5 Gg/year to 2.9 Gg/year, with an average annual growth rate of around 5%. This indicates that emissions have risen in tandem with usage. The removal of SO₂F₂ from the atmosphere relies primarily on surface ocean hydrolysis and hydroxyl radical reactions, and its long-term persistence could have significant climate impacts.
Looking ahead, with further phase-out of methyl bromide and growing global fumigation demand, the use and emissions of sulfuryl fluoride are expected to continue rising. This trend reflects both the market expansion potential of the chemical and the associated environmental regulatory challenges.
Environmentally Friendly Fumigation Technologies
Environmentally friendly fumigation technologies typically involve the use of fumigant gases in enclosed spaces to eliminate pests and microorganisms while minimizing harm to the environment and living organisms. Traditional fumigants may pose toxicity risks to humans and the environment, whereas “green fumigation” emphasizes the use of chemicals with lower environmental and human toxicity. Fumigation is widely applied in agriculture to protect crops, grains, and soil from pest damage. For exported wood products, fumigation can prevent the entry of live insects, enabling fumigation certification and compliance with import-export regulations.
For example, biofumigation is a natural, eco-friendly, and promising alternative to methyl bromide fumigation. It often involves soil fumigation where volatile gases are generated through the decomposition of plant metabolic products, inhibiting or killing soil-borne pests and diseases. Common biofumigant plants include species from the Brassica genus, mustard, rapeseed, and cauliflower. These plants can be used in crop rotation or intercropping systems to control soil-borne pathogens effectively.
Driving Factors
Gradual Phase-Out of Methyl Bromide and Other Traditional Fumigants
A major driver of the sulfuryl fluoride fumigant market is the regulatory restriction on traditional fumigants, particularly methyl bromide. Methyl bromide has been widely used for fumigation of buildings and commodities, but it is an ozone-depleting substance regulated under the Montreal Protocol. Over the past two decades, many countries have gradually phased out or strictly restricted its use, creating a pressing need for effective and legally compliant alternatives. Sulfuryl fluoride fumigant has become a primary substitute because it does not directly deplete the ozone layer and has been approved for fumigation of residential and commercial buildings. The gradual phase-out of methyl bromide has accelerated the adoption of sulfuryl fluoride across multiple sectors. Structural fumigation, especially in residential and commercial buildings, has significantly shifted toward sulfuryl fluoride due to its superior material penetration and lower residue. Similarly, in agricultural and food storage applications, sulfuryl fluoride has emerged as a reliable replacement, ensuring compliance with global environmental regulations.
Urbanization and Infrastructure Development
Another key factor driving the demand for sulfuryl fluoride fumigant is global urbanization and the expansion of infrastructure. As more residential, commercial, and industrial buildings are constructed, the risk of termites, cockroaches, bedbugs, and other pests also increases. These infestations pose serious economic and health challenges, driving strong demand for efficient structural fumigants.
Sulfuryl fluoride fumigant is non-flammable, non-corrosive, and capable of rapidly penetrating building materials. Since its introduction in the U.S. in 1961, it has been widely used for fumigating residential buildings, various public and commercial structures (including museums, libraries, archives, churches, government buildings), and historical sites. The construction sector remains its largest application area. Compared with methyl bromide, sulfuryl fluoride penetrates building materials more quickly, achieves broader-spectrum pest control, leaves lower residues, and has effectively replaced methyl bromide in termite control.
Its ability to penetrate building materials and control multiple pests makes sulfuryl fluoride fumigant particularly important in urban environments. Its efficacy against termites has been a key factor in its widespread adoption in countries with large residential construction volumes, such as the U.S., Japan, and emerging Asian markets. Urbanization also drives demand for commercial infrastructure, including offices, hotels, hospitals, and museums, where pest infestations could harm reputation and trigger regulatory issues.
Moreover, modern urban populations are increasingly aware of health risks posed by pests. This awareness has boosted demand for professional pest control services, which primarily use sulfuryl fluoride fumigant for building fumigation. Urban development, rising disposable incomes, and the proliferation of professional services together form a reinforcing cycle that supports sustained market growth. In emerging economies, ongoing infrastructure expansion is expected to continue supporting sulfuryl fluoride demand. As residential and commercial real estate projects grow, especially in the Asia-Pacific and Latin America, the need for certified fumigation solutions is likely to rise alongside urbanization rates.
Expansion of Grain Storage and Commodity Protection
Protecting stored food is an important driver of the sulfuryl fluoride fumigant market. In both developed and developing countries, pests such as beetles, weevils, and rodents can cause significant post-harvest losses. Sulfuryl fluoride fumigant can effectively fumigate stored grains, nuts, legumes, and other commodities, making it an essential preservative in large storage facilities, warehouses, and processing centers.
Studies have shown that sulfuryl fluoride effectively eliminates pests that harm food. Fumigation trials on nuts, cereals, flour, and other key food items have examined residue levels, demonstrating that sulfuryl fluoride does not affect food taste or quality. In September 2003, the Swiss government officially approved sulfuryl fluoride for commercial food fumigation, becoming the first country to use it as a replacement for methyl bromide in food applications. In January 2004, the U.S. Environmental Protection Agency registered sulfuryl fluoride for food fumigation, and by July 2005, set residue standards for its use in food. Italy, the U.K., Germany, Canada, France, and other countries have also approved sulfuryl fluoride for fumigating stored food.
Global population growth, rising food demand, and expanding agricultural trade directly drive the use of sulfuryl fluoride fumigant in commodity protection. As food safety regulations and residue standards become stricter in major markets such as the U.S., Europe, and parts of Asia, sulfuryl fluoride provides a safe and effective solution that ensures compliance while maintaining product quality. Additionally, with global supply chains increasingly relying on container transport, the risk of cross-border pest spread rises. Using sulfuryl fluoride for import-export fumigation helps prevent invasive species and meet quarantine regulations, further solidifying its role in food security and trade.
With growing investments in modern storage infrastructure and strengthened pest management systems, demand for high-efficiency fumigants like sulfuryl fluoride is expected to continue rising.
