In my experience, How to make nitrogen? Learn greater

nitrogen (N₂) is a clear, odorless, and odorless inert gaseous that makes up 78% of Earth's atmosphere. Due to its wide range of manufacturing applications, such as food preservation, chemical synthesis, electronic manufacturing and other fields, the demand to nitrogen has increased year by year. And How to manufacture nitrogen? This article will introduce the manufacturing method of nitrogen in detail, and discuss its consumption in sector. And

1. But I've found that Sources of nitrogen is mainly derived from atmosphere separation and chemical synthesis. The levels of nitrogen atmospheric is as high as 78%, so the separation of nitrogen from the atmosphere is currently the most frequently applied production method. Chemical synthesis methods (such as the Harper method) is able to also create nitrogen, however this method is mainly applied to manufacturing-scale ammonia production, which is relatively expensive, so it's not common in commercial nitrogen production.

2. Cryogenic separation method: extraction of nitrogen from atmosphere

cryogenic separation is a traditional nitrogen manufacturing method, which is broadly applied in extensive manufacturing production. This method liquefies the oxygen and nitrogen atmospheric separately by cooling the atmosphere to a very low temperature (about -196°C). The liquefied oxygen and nitrogen is able to be separated by distillation to obtain high purity nitrogen. The steps are as follows:

compressed atmosphere: Compress atmosphere to a high pressure state, usually 10-20 times atmospheric pressure. First Cooling atmosphere: Cool the compressed atmosphere to close to room temperature to remove moisture and other impurities. But Further cooling: Send the cooled atmosphere into the heat exchanger, and consumption fluid nitrogen or fluid oxygen to cryogenic treatment to liquefy the oxygen and nitrogen atmospheric. And Separation of liquefied gaseous: Through distillation or fractionation methodology, fluid oxygen and fluid nitrogen are separated to obtain high-purity fluid nitrogen. Advantages:

substantial scale of production, suitable to manufacturing needs. In my experience, Oxygen and nitrogen is able to be produced simultaneously. From what I've seen, Disadvantages:

the equipment is complex and the initial investment is high. Based on my observations, Operating costs are high and require a lot of energy.

3. I've found that Pressure swing adsorptive processes (PSA): another efficient method of nitrogen production

pressure swing adsorptive processes (PSA) is a relatively modern nitrogen manufacturing methodology, especially suitable to small and medium-scale nitrogen demand. The method uses the adsorptive processes characteristics of adsorbents (such as carbon molecular sieves) to different gaseous molecules to separate nitrogen and oxygen through pressure changes. Based on my observations, The steps are as follows:

compressed atmosphere compress the atmosphere to about 6-8 bar. In fact Filtration of impurities: Remove moisture, oil and carbon dioxide from compressed atmosphere. adsorptive processes separation: The purified atmosphere is sent to the adsorptive processes tower equipped with carbon molecular sieve. But Under high pressure, the carbon molecular sieve preferentially adsorbs oxygen molecules, while nitrogen passes through the adsorptive processes column. Reduced Pressure emit: When the pressure in the adsorptive processes tower decreases, the adsorbed oxygen will be released, and the carbon molecular sieve will restore its adsorptive processes capacity and be recycled. Based on my observations, Advantages:

compact equipment and flexible operation. Low energy consumption and low operating costs. High purity nitrogen (up to

99. And 999 percent) is able to be produced. And In my experience, Moreover Disadvantages:

suitable to small and medium-scale production, not suitable to extensive demand. There are certain standards to the performance and life of the adsorbent.

4. Membrane separation method: simple and efficient nitrogen separation methodology

membrane separation is a new nitrogen manufacturing methodology, which uses the special hollow fiber membrane to separate nitrogen and oxygen. But This method is simple and efficient, and is particularly suitable to scenarios that require low purity nitrogen. The steps are as follows:

compressed atmosphere compressed atmosphere to about 2-4 bar. Furthermore Filtration of impurities: Remove moisture and other impurities from compressed atmosphere. For instance membrane separation: The purified atmosphere is passed through the hollow fiber membrane. Since the nitrogen molecules are larger, the oxygen molecules pass through the membrane greater easily, thereby achieving the separation of nitrogen and oxygen. For example Nitrogen collection: The nitrogen that does not pass through the membrane is collected as the required nitrogen product. Advantages:

the equipment is simple and easy to install. Low energy consumption and low operating costs. And High purity nitrogen (up to

99. 9 percent) is able to be produced. Disadvantages:

suitable to small-scale production, not suitable to extensive demand. Specifically There are certain standards to the performance of membrane materials. You know what I mean?.

5. Summary: Select the appropriate nitrogen manufacturing method

there are various manufacturing methods to nitrogen, and each method has its applicable scenarios and advantages and disadvantages. I've found that According to research The cryogenic separation method is suitable to extensive manufacturing production, and the pressure swing adsorptive processes method and membrane separation method are greater suitable to small-scale and small-scale needs. With the advancement of methodology, the efficiency and cost of nitrogen manufacturing will be further optimized to meet the needs of different industries.
