The global air separation plant market size accounted for USD 6,522 million in 2024 and is expected to exceed around USD 10,623 million by 2034, growing at a CAGR of 5% from 2024 to 2034.
The air separation plant market refers to the production, distribution, and use of these plants, which separate atmospheric air into its primary components, typically oxygen, nitrogen, and sometimes also argon and other rare inert gases. Fractional distillation is the most common method for air separation. These plants are used to produce inert gas, coal gas, and ammonia. In the food and beverages industry, an air separator unit (ASU) is used to package and preserve products. There is a high demand for this separation plant in pharmaceutical, biotechnology, aerospace, electronics, energy and power, chemicals, mining, and oil & gas, which is driving the growth of the air separation plant market.
However, the risk factors of the market include the presence of water vapor and moisture, improper functioning of the equipment, high initial investments, and supply chain disruptions that can be barriers to the growth of the market. The future scope of the market includes the production of high-purity hydrogen gas, strategic partnerships and collaboration, improving decision-making, and integration of automation and artificial intelligence that will help the growth of the air separation plant market.
