Description

Technical Field

[0002] Nitrogen buffering is a technology that utilizes the physical properties of nitrogen to stabilize or control pressure and temperature changes. In industrial applications, nitrogen buffers are usually used to absorb pressure fluctuations in the system, protect equipment from damage, and ensure the smooth operation of the process. The working principle of a nitrogen buffer is to utilize the compressibility of nitrogen. When the pressure in the system suddenly increases, the nitrogen in the nitrogen buffer is compressed, absorbing part of the pressure energy, thereby reducing the pressure peak and protecting downstream equipment from high-pressure impacts. Nitrogen buffers play a crucial role in industrial applications. They can stabilize nitrogen supply, reduce pressure fluctuations, and ensure the continuity and stability of the process flow. If the nitrogen buffer cannot perform split-tank buffering, the following problems may occur:
