Main products ：
 

PSA Oxygen Plant

  
 

A PSA (Pressure Swing Adsorption) PSA Oxygen Generator is a device that separates oxygen from air using the principle of pressure - swing adsorption. It typically contains two adsorption towers filled with zeolite molecular sieves. When air is compressed and enters the tower under high pressure, nitrogen and other trace gases are adsorbed by the molecular sieves, while oxygen passes through and is collected. When the adsorption capacity of one tower reaches saturation, the process switches to the other tower, and the saturated tower undergoes regeneration by depressurization to release the adsorbed gases. Psa Oxygen Gas Generatorare widely used in industries such as metal smelting, chemical production, and medical oxygen supply.
 

Oxygen Plant


 

An Oxygen Plant is a general term for equipment that produces oxygen. It can use various methods for oxygen production, including cryogenic air separation, PSA, and membrane separation. Cryogenic air separation plants cool and distill air at extremely low temperatures to separate oxygen, nitrogen, and other components. Mobile Oxygen Plant are capable of producing large quantities of high - purity oxygen and are commonly used in large - scale industrial applications, such as in the steel industry for oxygen - enriched combustion to improve the efficiency of steelmaking processes.
 

Nitrogen Plant
 

A Nitrogen Plant is designed to produce nitrogen gas. Similar to oxygen plants, nitrogen can be produced through cryogenic air separation, PSA, or membrane separation methods. In cryogenic nitrogen plants, air is liquefied and then distilled to separate nitrogen from other components. Nitrogen Production Unit use adsorbents to selectively adsorb oxygen and other impurities from compressed air, leaving nitrogen gas. Nitrogen plants are used in many industries, such as food packaging to provide an inert atmosphere for product preservation, and in the electronics industry for semiconductor manufacturing processes.
 

VPSA Oxygen Plant


 

A VPSA (Vacuum Pressure Swing Adsorption) Oxygen Plant is a variation of the PSA technology. It operates at a lower pressure range compared to traditional PSA. The VPSA process uses a vacuum pump to assist in the regeneration of the adsorption towers. This allows for a more efficient removal of adsorbed gases, reducing the energy consumption for regeneration. VPSA Oxygen Gas Plant are often used in applications where a large amount of oxygen is required at a relatively lower purity level, such as in wastewater treatment plants for aerobic biological treatment processes.
 

Air Separation Unit


 

An Air Separation Unit (ASU) is a complex industrial facility that separates air into its primary components, mainly oxygen, nitrogen, and argon. The most common method used in ASUs is cryogenic distillation. Air is first compressed, cooled, and then sent to a series of distillation columns. In these columns, through the process of repeated condensation and evaporation at different temperatures, oxygen, nitrogen, and argon are separated based on their different boiling points.Oxygen Air separation Unit are crucial in industries such as steelmaking, chemical production, and electronics manufacturing, where high - purity oxygen, nitrogen, and argon are essential for various processes.
 

CO₂ Plant

A CO₂ Plant is used to produce carbon dioxide gas. It can obtain CO₂ from various sources, such as flue gas from power plants or industrial processes, or through chemical reactions. For example, in some fermentation processes, CO₂ is a by - product that can be captured and purified. CO₂ plants may use technologies like absorption, adsorption, and distillation to purify and liquefy the CO₂. Co2 Production Plant is used in many applications, including carbonation in the beverage industry, as a refrigerant in some cooling systems, and in enhanced oil recovery in the oil and gas industry.
 

Gas Compressor


 

A Gas Compressor is a mechanical device that increases the pressure of a gas by reducing its volume. There are different types of gas compressors, such as reciprocating compressors, centrifugal compressors, and screw compressors. Reciprocating compressors use a piston - cylinder arrangement to compress the gas. Centrifugal compressors rely on the high - speed rotation of impellers to impart kinetic energy to the gas, which is then converted into pressure energy. Screw compressors use two intermeshing screws to compress the gas. Gas compressors are essential in many industrial processes, including gas transportation in pipelines, air compression for pneumatic tools, and in the operation of various gas - based industrial plants.
 

ISO Tank


 

An ISO Tank is an intermodal tank container designed and constructed in accordance with international standards (ISO - International Organization for Standardization). These tanks are used for the transportation and storage of various liquid and gaseous substances, including chemicals, food products, and gases.Oxygen storage Tank are made of high - quality materials to ensure the safe containment of the substances. They are equipped with fittings for filling, discharging, and pressure control. These tanks can be easily transported by different modes of transportation, such as trucks, trains, and ships, making them a convenient and standardized solution for the global transportation of bulk liquids and gases.
