On 15th April 1883, a polish physicists name Karol Olszewski and Zygmunt Wroblewski, first liquefied the nitrogen. Since then it has been used for various purposes and the liquid nitrogen market is expanding exponentially. In this blog, we will read some of the facts about liquid nitrogen, and its uses.
What is Liquid Nitrogen and how is it made from Nitrogen?
The liquid nitrogen is denoted as LN, LN2, or LIN. Liquefied nitrogen is the liquid form of the element nitrogen. The nitrogen is produced by the process of fractional distillation of the liquid air. The nitrogen gas is odorless, colorless, and non-toxic. The liquid nitrogen is made from the nitrogen through cryogenic air separation. Although the basic technique was developed in the 20th century and still it is being used with an improved version.
The process starts with compressing nitrogen gas in the large compressors. The process of compression makes the temperature go higher. The hot compressed nitrogen is further passed through the heat exchangers to reduce the temperature. An absorbent material is utilized to eliminate the carbon-di-oxide and water. The air is passed through the heat exchanger which cools down the incoming air. Gradually the air becomes cold and starts to liquefy. The liquid air can be distilled and boiled multiple times. The nitrogen is condensed at the cryogenic temperature and then liquid nitrogen can be obtained. Finally, the liquid nitrogen can be collected in Dewar’s vessel for several industrial purposes.
Where is liquid nitrogen stored?
The liquid nitrogen is stored in well-ventilated areas and cannot be stored in some uncovered containers for a longer period of time.
Uses of Liquid Nitrogen-
- Liquid nitrogen is used for removing skin lesions like actinic keratosis and warts.
- Widely used to store cells in laboratories at low temperatures.
- In a hypoxic air fire prevention system, the liquid nitrogen is used as a backup nitrogen source.
- The liquid nitrogen is used to freeze oil and water pipes. The freezing of the water and oil pipes is done to block the flow of the fluid in the work area.
- In the process of cryopreservation of blood, liquid nitrogen is used to preserve biological samples such as eggs and sperm. Also, liquid nitrogen plays an imperative role to enable the animal genetic resource cryo conservation process.
- Liquid nitrogen is utilized in the process of food preparation such as ice creams.
- The compound is most widely used in the liquid nitrogen market as a coolant for the following purposes:
- The LN is used to achieve superconductivity in the semiconductors
- Extensively used in facilitating the extremely low-temperature reactions in the chemistry
- To shrink the various mechanical components during the machine assembly process
- Liquid nitrogen is used as a coolant in the conducting controlled evaporation processes
- For maintaining a lower temperature around liquid helium cooling system
- As a coolant for computers.
- Cameras in astronomy
- Used in making nitrogen fog and flash-freezing.
- LN is used as a source of dry gas
- Protecting the materials from oxygen exposure
- Liquid nitrogen is also widely used in food processing because it prevents the oxidation in packaging
- Liquid nitrogen is extensively used in the places such as, bars, restaurants, and pubs. The liquid nitrogen creates a fog effect on the table and it becomes very pleasing to the eyes of the customers.
- Containers such as crycan (made by Indian Oil Corporation Ltd) are non-pressurized and double-walled aluminum containers that are specially used for preserving bull semen under severely cold temperatures. The semen of a bull is further utilized for insemination in order to get a better breed of cows.
In a nutshell,
The myriad of uses of liquid nitrogen is increasing its demand in the market. With the advancement of the medical field, increasing globalization, widening hospitability sector, and rising investment in research, the liquid nitrogen market is expected to witness unwavering growth. Various leading companies are already rending the best of the services and making an immense profit. The regions such as China, India, and Japan expanding their petrochemical industry, and the region is estimated to render lucrative opportunities for market growth.
