[Suzhou XITE Gas] The difference between liquid nitrogen and nitrogen gas

Nitrogen is a naturally occurring non-metallic element. In the periodic table, we use the symbol N to denote it. This element is inert. Moreover, it constitutes 78% of the atmosphere of our planet. However, you must remember that gaseous nitrogen is natural.

Liquid nitrogen is not naturally occurring. We use a low-temperature air separation process to liquefy this non-metallic element. However, chemically speaking, gaseous nitrogen and liquid nitrogen are the same and are both composed of N2 molecules.

However, the essential difference between liquid nitrogen and nitrogen is that the former is man-made, while the latter exists in nature. We will discuss nitrogen and liquid nitrogen in detail later. First, we will go through a short snapshot of them below.

Liquid Nitrogen Vs Nitrogen.

Liquid Nitrogen (LIN)

It is artificially produced

Liquid Nitrogen

Liquid phase

Exposure to liquid nitrogen can make materials brittle

Harmful to living tissue

Applications include preservation of semen, blood samples and other biological samples, frozen food, branding of cattle, skin treatment and cryotherapy.


Occurs naturally and makes up 78% of the atmosphere.

Nitrogen in the gas phase

Gaseous phase

Usually not dangerous

No effect on materials

Applications include use as a covering agent for protecting food from oxidation, transporting hazardous products, filling tire tubes, making beer kegs, etc.

What is liquid nitrogen?

So we've talked about the difference between liquid nitrogen and nitrogen. Now we will look in more detail at what liquid nitrogen is. Liquid nitrogen is liquefied nitrogen at very low pressure. We refer to the liquefied gas as a cryogenic liquid or simply as a cryogenic gas.

A cryogenic liquid is a liquid gas with a boiling point below -90 degrees Celsius. Similarly, LIN is a cryogenic agent with a boiling point below -195.8 degrees Celsius. In short, we denote it as LIN. typically, it has many properties similar to nitrogen.

It is inert, colorless and odorless. And, you should be careful when handling LIN. Touching liquid nitrogen can be hazardous to bare skin. Industry uses liquid nitrogen plants, which produce liquid nitrogen by fractional distillation.

What is nitrogen?

Nitrogen is a gas that occurs naturally in the earth's atmosphere. It is inert, colorless and inert. In fact, industry values the inert nature of this gas. As one may know, it makes up about 78% of our atmosphere.

Obviously, nitrogen is the industrial gas that is consumed in specialized quantities. We find it in use in all walks of modern life. It is used in the manufacture of ammonia, fertilizers, pharmaceuticals, food packaging and chemical products.

Advantages of owning a field nitrogen generator (nitrogen generator):

Before using the nitrogen generation system on site, many enterprises in the industry have no choice but to buy nitrogen elsewhere. However, the use of on-site nitrogen generator can eliminate all the troubles related to bulk purchase of nitrogen. Our nitrogen generator is an option with the greatest benefit: the average cost of producing nitrogen by ourselves is one-third to one-half lower than the relevant cost of purchasing nitrogen. Using the on-site nitrogen generator system, there is no need to pay the freight when purchasing nitrogen. Our nitrogen generator system usually allows you to recover the cost within 18 months.

In addition to economy, the nitrogen generator system of the on-site nitrogen generator also provides:

Reliability - the nitrogen generator system, that is, the on-site nitrogen generator system, uses the surrounding air to generate nitrogen. Therefore, our customers never have to worry about the shortage of nitrogen. Reduce stress - improve safety through storage. Simple - we make it easy for people without relevant equipment experience. The visual touch screen control can control the stability of gas purity. At the same time, it can operate self diagnosis, visual operation diagram and maintenance plan reminder on the screen. Flexibility - our equipment is small and can be transported under various conditions, so as long as there is air and electricity, the equipment can operate stably anywhere. Fully automatic - once a downstream request is detected, production begins.

Why use XITE nitrogen generator?   Our nitrogen generator system provides reliable on-site nitrogen supply for various industries, which is famous in China and Southeast Asia. Our on-site nitrogen system can produce nitrogen with purity up to 99.999%. For our nitrogen generator, it can meet the nitrogen production in any place and any complex environment.
