Cryogenic Nitrogen Plant

Cryogenic nitrogen plant sucks air from the atmosphere that comprises of gases such as nitrogen, oxygen and various others. Nitrogen is said to constitute around 78% of earth’s atmosphere by volume. It is called as the largest industrial gas because of its application in various industrial and medical applications. After atmospheric is tapped it is moved into an air compressor where it is compressed and moved into a cleanup where impurities such as hydrocarbons, moisture and carbon dioxide are removed. Thereafter, it is run through a heat exchanger where the air is cooled to cryogenic temperatures. Then, it is moved into a high distillation column where nitrogen is separated from oxygen and other gases and is distilled till it meets industrial and medical specifications. Our plant machinery is constructed as per international standards.

How Does Cryogenic Nitrogen Plant Work & Process

We use the latest cryogenic technology in constructing cryogenic distillation. Since we are focused on constructing high quality cryogenic nitrogen plant and liquid nitrogen plant, we pay a great deal of attention to building nitrogen machines with solid designing. We have experts that help you install and commission cryogenic nitrogen generation plant, cryogenic nitrogen plant cost. Our clients from various industries now prefer using cryogenic nitrogen plants because liquid nitrogen is easy to store and transport. Moreover, liquid nitrogen is less likely to leak even though nitrogen is widely used as a gas. It is said that around 50 million tons of nitrogen gas is generated every year. Liquid nitrogen plants are preferred by our customers all over the globe since liquid oxygen is easy to transport and store. We offer the plant in various sizes and capacities ranging from 20 liter/hour to 500 liter/hour and cryogenic nitrogen plant 450 nm3/hr (651.15 litre liquid). Purity of nitrogen produced in our plants is around 99.99%.

Liquid Nitrogen and its Various Applications

Liquid nitrogen is used in medical an industrial applications. It is also used in the industrial manufacturing of ammonia, which is important for making numerous industrial products such as nitric acid, fertilizers, pharmaceutical products, and explosives. Because of its inerting properties, nitrogen is used in preserving food products and making diodes and transistors. Liquid nitrogen is used for cryo-surgery, storing sperm and other cellular materials for medical or research purposes. It  also acts as a refrigerant for preserving  texture, flavor, color and moisture of food. Numerous other applications include:

• Preservation of food( Food Packaging industry)
• In the manufacturing of incandescent bulbs
• In the making of stainless steel
• For decreasing fire hazards in aircrafts
• For cryo-preservation of blood, reproductive cells and other biological materials

Salient Features of Cryogenic Nitrogen Plant

Scope & Supply of Nitrogen gas Plant

• Air Compressor : Rotary air compressor screw type can be used for smaller size plants upto 50 m3/hr & 1000 m3/hr. Upto 40000m3/hr. Centrifugal compressor can be used for higher size plants.
• Air pre cooling system: Air separation plants adopt chilling system in all air pre-Cooling systems.
• Air purification system: Molecular sieves are used in the air purification system to remove the Co2 & moisture for the process air at low- Pressure.
• Air separation column: (Air separation column-cold box) consists of outer steel casing, Main heat exchanger, liquefier, Bottom column, Top column, Condenser, Sub-cooler, Liquid oxygen & nitrogen filter. Cooling pipe line, insulation material, Digital electronic temperature indicator & scanner, PT 100 sensor, DP gauge monometer, Expansion valve with long stem type with pointer & index & wheel -1 set.
• Expander: Expander is used for giving cooling to the air for the liquefaction process and broken by booster, so as to reduce the expanded air volume, stabilize the upper columns working condition and reduce power consumption. The turbine expanders have complete trouble free working and long life and reliability.
• Control Panel: Nitrogen gas plants can be configured for automatic operation through a pc. This will use out switching valves of German or Japanese and motorized cryogenic valves on cold box.
