What is a Cryogenic Liquid Nitrogen Plant?

1. Introduction

  • the cryogenic liquid nitrogen plant is a production base of cryogenics, mainly for the chemical industry, energy, and pharmaceutical;
  • it has a capacity ranging from 20 cum/hr to 10000 cum/hr.
  • Our company ZHONGRUI is a high-tech enterprise, which produces liquid nitrogen with crystallization technology and a very powerful operation.
  • We have made great achievements in the field of liquid nitrogen in the past few years.

2. What is a Cryogenic Liquid Nitrogen Plant?

A cryogenic liquid nitrogen plant (CLNP) is a large-scale industrial facility for the production of liquid nitrogen. The main purpose of the CLNP is to provide a source of high-quality nitrogen for the production of liquid chemicals, food products, and pharmaceuticals.
These plants can be found worldwide but are most common in Europe and Asia. They are mainly used by chemical, pharmaceutical, and food industries to produce nitrogenous compounds such as oxygen, nitric acid, nitrobenzene, and ammonia compounds. The first CLNP was opened in Japan in 1939 and over the next few decades, several more have been built around the world.
The chemical industry has traditionally used LCNPs because of their high purity levels and power output capabilities. Another reason to use these plants is that they are very efficient sources of refrigerated air which reduces energy consumption compared with other processes.
Other uses include reclamation of chemical waste; treatment of wastewater; purification of water; cooling applications such as cooling towers or heat exchangers; emissions control systems; solid-state chemical processing units; separation techniques including chromatographic separation techniques like gas chromatography coupled to mass spectrometry (GC-MS) or electrospray ionization (ESI). In recent years there has been increased interest in developing CLNP facilities for industrial gases such as hydrogen sulfide, propane, or methane gas, or even fuel gases such as ethane or propane used in chemical processing plants or HVAC systems!
In order to cover all these possible uses, it is important to have a well-trained staff on site who can monitor all operations closely during their operation period for any problems arising during the production process, manage maintenance work during periods when no operations take place, provide equipment repair services and maintenance services, etc.; thus ensuring optimal operational safety and reliability at all times.
It is also important that the plant must be well located near populated areas because it will be necessary to collect raw materials from every part of the country and transport them across hundreds of miles on board trucks with temperatures ranging from minus 60 degrees Celsius (- 74F) up to plus 50 degrees Celsius (122F).

3. The Purity of a Cryogenic Liquid Nitrogen Plant

Because of its low molecular weight, nitrogen is considered to be the most stable and pure form of nitrogen. The liquid nitrogen plant can generate pure nitrogen and oxygen with a purity of 99.99% and 99.7% respectively.
But what do all these numbers mean? How does this plant function?
The plant is divided into three different parts: a cryogenic liquid nitrogen storage unit, a cryogenic liquid nitrogen production unit, and an oxygen generating unit. The cryogenic liquid nitrogen storage unit stores the liquid nitrogen in a structure that keeps it at a temperature below -271 °C (-505 °C for long-term storage). As air circulates around the storage unit during the night, it heats up and condenses on the surface of the liquid nitrogen, which is then pumped out to create pure atmospheric air. The process continues until all of the pure atmospheric air has been produced.
As you can see from this diagrammatic representation, as well as being used to store liquid nitrogen at extremely cold temperatures (cryogenics), cryogenics has also been used in nuclear reactors, where unburned fuel rods are kept in a form that prevents them from overheating – essentially “freezing” before they burn up in the reactor core.
This means that when we want to use our cryogenics units to make more pure air than we need – or convert some other non-condensing gas (such as carbon dioxide) into pure atmospheric air – it’s possible to convert one part of an existing plant into another part by simply adding or removing components from one part to another.
It’s also possible for us to make a slight modification to our existing plants (adding new components) without having to completely redesign them; this is known as modularization and it allows us not only to produce larger quantities than we do today but also increase our efficiency; there is no need for us ever build new plants again if we can reuse old ones!
Storing the liquid nitrogen at extremely low temperatures creates new challenges too; although there are some areas that have shown that cold temperatures may have some benefits such as reducing corrosion rates, there are others that suggest they could be harmful such as ice formation and contamination with gases such as carbon dioxide which are also very dangerous in nature (the presence of carbon dioxide reduces photosynthesis rate by 10-15%).
Rather than worrying about these issues – which only apply marginally at best – focusing purely on storing purified air allows us more freedom

4. The Advantages of a Cryogenic Liquid Nitrogen Plant

Liquid nitrogen is a compound that is extremely cold, but not sufficiently so for it to be “freezing”. It has the same chemical composition as water, but it has a much lower boiling point and can be stored for very long periods of time without reaching a dangerous temperature.
This compound is used in cryogenic liquid nitrogen plants to generate nitrogen and oxygen. Although this chemical can be used from the ground up and there are no manufacturing costs associated with it, liquid nitrogen requires special equipment and refrigeration technology to make it safe to store.
Therefore, liquid nitrogen has some advantages over other types of cryogenic processes:
  • It is extremely cold, but not enough to be freezing (i.e., freezing at near absolute zero)
  • It remains stable in storage after long periods of time without losing its chemical composition
  • It can be stored indefinitely without exposure to any other chemicals or organisms (this makes the chemical safe for long-term use)
In addition, liquid nitrogen is incredibly efficient: compared to other forms of energy generation such as oil, gas, or coal exploitation there are virtually no emissions of carbon dioxide into the atmosphere from a production process involving liquid nitrogen. Liquid nitrogen also produces fewer emissions per unit volume than any other form of energy generation because it does not interact with the environment as oil or gas does.
With this information about cryogenic liquids, you should have an idea about what you should look for when buying one and how the process works; then you can start investigating the options available for your company when looking for one.

5. Conclusion

Having covered the basics of liquid nitrogen, and its applications in cryogenic processing, let’s look at the end of its cycle.
In the earlier part of this post, I covered briefly how liquid nitrogen is applied to a number of useful processes including dentistry, food processing, and medicine.
A plant to produce nitrogen gas (from which liquid nitrogen is derived), has a capacity ranging from 20 cum/hr to 10000 cum/hr, with a maximum capacity of 10000 cum/hr. The plant can be run 24 hours/day or night (depending on the demand). The process is done in stages: 60%, 40%, 20%, and 10% are added to deaerated water. Finally, there will be at least 99.7 percent purity left over once activated. Once activated there is no further need for the deaerated water. It can be kept for a long time without any loss in taste or aroma.
The process goes through three stages: 60%, 40%, and 20% are added to deaerated water; finally, there will be at least 99.7 percent purity left over once activated (which can be kept for a long time without any loss in taste or aroma). Once activated it can be kept for a long time without any loss in taste or aroma.
This works very well with both cement and concrete; where it is used as a curing agent (i.e.: on concrete) it becomes more effective when mixed with sandblasting agents. But other than that it has many industrial applications such as chemical processing, synthesis, equipment maintenance and transport of hazardous materials, etc… It also has many medical uses including cancer treatment, burns treatment, etc…
