Nitrogen has many uses and based on the industry, it can be utilized for a wide range of dust and objectives. Nitrogen does not have any color and smell and it makes up about 78% of the atmosphere. Even though it is popularly associated with our surroundings, industrially manufactured nitrogen is used in many applications. In case one of your systems needs frequent purging, have a look at what you need to know regarding the different methods and procedures.
What does nitrogen purging mean? It is an industry-standard procedure that involves displacing any unwanted or dangerous atmosphere with an inert nitrogen atmosphere. In case you operate in an industry where there is the pollution of harmful gases, then you should consider nitrogen purging.
Why do we use nitrogen for purging? Nitrogen is dry and cannot catch fire. Therefore, the nitrogen displacement of flammable gases will stop any unstable and prospective atmosphere that can be ignitable. In other words, using nitrogen in oil and gas industry equipment efficiently eliminate moisture and oxygen and forms a stable climate.
Have a look at some of the various nitrogen purging systems. When talking about nitrogen purge, different systems and methods are involved. Each of them needs different equipment. the different types of nitrogen purging systems. Have a look at them.
Pressure transfer of liquids. in certain situations, you would want to transfer liquid without utilizing a pump. If you want to finish this task, nitrogen will enable you to pressurize the headspace through a vessel. This method is usually used in case of any space barriers or if there are materials that affect the efficiency of the pump.
The pressure-hold vacuum method. When situations do not allow a sweeping action of nitrogen you can use a vessel to pressurize nitrogen. The moment of the contents inside the vessels have mixed with nitrogen, the illusion takes place. This method is appropriate if the vessel has a single opening.
Displacement purging. If the equipment has simple cross-sections like the ones found in pipelines, then this method can come in handy. The amount of nitrogen needed depends on the volume of the pipe. As opposed to the different methods like dilution purging, it is easy for you to purge a system without appreciable dilution.
Dilution purging. This method comes in handy especially for obligated systems and equipment cross-sections that involved kilns, columns, and many more. When you mix the nitrogen with the gas you should purge, the contents can be patched through an outlet point which needs to be a distance from the inlet point.
Here is how the nitrogen purging procedure works. The objective of the nitrogen purging system is to wash pipes and other parts that may have contaminants. If you do that, you are going to greatly reduce the dangers that come with harmful elements such as oxygen. Based on the type of method you use, nitrogen can either flow art high or low pressures.
