Oxy-fuel combustion technology uses high-concentration oxygen as a combustion enhancer, significantly improving combustion efficiency (by 15–25%) and flame temperature (by 200–300 °C). At the same time, it reduces ignition points and accelerates reaction rates, thereby achieving energy savings and consumption reduction. This technology lowers flue gas emissions by 20–30%, increases thermal efficiency by 15–20%, and supports carbon capture. Thanks to advances in oxygen generation technology, oxy-fuel combustion has been widely applied in steelmaking, nonferrous metallurgy, industrial furnaces, and hazardous waste treatment, offering both high efficiency and environmental benefits.

With its outstanding oxidation properties, ozone is widely applied in water treatment, flue gas denitrification, and paper bleaching. Due to its inherent instability (half-life of 20–30 minutes), ozone must be generated on-site, driving the rapid growth of China’s ozone generator market, which has reached 5.8 billion RMB with an annual growth rate of 12%. Among these applications, water treatment accounts for 55% of the demand. VPSA oxygen generation technology has become the mainstream choice, offering significant advantages such as 40–50% cost reduction, oxygen purity of 90–93%, and energy consumption below 0.30 kWh/Nm³. Under the impetus of stringent environmental policies, the market demand for VPSA equipment is projected to exceed 2 billion RMB in the next three years.

In China’s industrial oxygen market, VPSA oxygen generation equipment leasing and professional operation services have emerged as a leading model, enabling clients to concentrate resources on their core business while securing a stable supply of high-purity oxygen (93% ±0.5%) with exceptional operational reliability. Through BOT (Build-Operate-Transfer) or entrusted O&M models, enterprises benefit from: • Over 35% reduction in oxygen cost per ton • Equipment availability above 99.5% • 15–18% reduction in unit energy consumption Leveraging extensive project experience, an intelligent O&M platform, and advanced energy-saving technologies (energy consumption ≤0.30 kWh/Nm³), VPSA oxygen generation continues to drive high-quality growth, leading the industry amid a rapidly expanding oxy-fuel market with an annual growth rate of 12%.

As a major steel producer, China annually generates over 800 billion cubic meters of carbon-rich off-gases, including blast furnace gas (containing 20-25% CO) and converter gas (containing 60-70% CO). Utilizing PSA technology to separate and purify these gases to a high purity (CO ≥98%) for C1 chemical production can reduce raw material costs by 30-40% and increase the value-added of the gases by 2-3 times.By integrating steelmaking and chemical production, by-product gases can be converted into methanol (0.1–0.15 tons per ton of steel), forming a “steel–chemical” symbiotic system that reduces carbon emissions per ton of steel by 8–12%.……
