Air Separation Plants Market Segmentation

The air separation plants market has been segmented based on type, process, gas, application, and region.

The global market by type has been segmented into under 20000 m3/h, 20,000-40,000 m3/h, 40,000-80,000 m3/h, and more than 80,000 m3/h. Among these types, in 2018, the global market was led by 20,000-40,000 m3/h segment and is projected to lead throughout the forecast period. The 20,000- 40,000 m3/h capacity type is used for air separation purposes. These are majorly used in the heat treatment process, welding, pulp & paper industry, the steel industry where certain gases that will react with and degrade the product, are removed. This expected to enhance the demand for the 20,000- 40,000 m3/h capacity type air separation plants in the global market during the forecast period.

Based on the process, the market has been segmented into the cryogenic distillation process and non-cryogenic distillation process. Among these processes, the cryogenic distillation process has accounted for the largest market share, followed by the non-cryogenic distillation process. Cryogenic distillation process separates oxygen from air by liquefying air at shallow temperature. Cryogenic air separation process relies on the differences in boiling points to separate air and purify into the desired gas supply and liquid products, such as oxygen, nitrogen, argon. It is used in medium to large scale plants to produce nitrogen, oxygen, and argon, as gases or liquid products. Moreover, all plants producing liquefied industrial gas products utilize cryogenic technology process, which enhanced the global market size for the air separation plants in 2018 and further expanding plants producing liquefied industrial gas is expected to raise the demand for the cryogenic technology process in the global market during the forecast period.

On the basis of gas, the global market has been segmented into nitrogen, oxygen, and others. In 2018, the oxygen segment dominated the market and projected to be dominant throughout the forecast period. The oxygen (O2) is an active, life-sustaining component of the atmosphere. It is colorless, odorless and tasteless & has poor solubility in water. The largest consumer of oxygen is the steel industry. Moreover, Oxygen has numerous uses in steelmaking and other metals refining and fabrication processes which are used in chemicals, pharmaceuticals, petroleum processing, glass, and ceramic manufacture and pulp and paper manufacture.

On the basis of application, the global market has been segmented into chemical, oil & gas industry, paper, metallurgy, and others. In 2018, the metallurgy segment dominated the market and projected to be dominant throughout the forecast period. Gases act as a manufacturer of casting molds to enhance their hardness. Moreover, they are also used to melt the steel and other metals and work as a shielding gas in the heat treatment of iron, steel, and other metals. The largest user of oxygen is the steel and metal industry. They are used to cool materials which are heat sensitive or soft at room temperature. Thus, these factors and features are expected to lead the global market growth for air separation plants during the forecast period.
