Application of the Self-Pressurization System in Liquid Oxygen, Nitrogen, and Argon Tanks

The self-pressurization system in liquid oxygen (LOX), nitrogen (LIN), and argon (LAR) tanks is a crucial component designed to maintain and control the internal gas pressure levels. The primary purpose of the self-pressurization system is to gasify a portion of the liquefied gas, creating a stable internal pressure, ensuring that the stored liquid can be released smoothly and consistently. Below is an explanation of how the system works and its main features:

Working Principle:

The self-pressurization system operates by heating or utilizing ambient temperature to vaporize a small portion of the liquid gas (such as liquid oxygen, nitrogen, or argon) inside the tank. This gasification increases the pressure within the tank, which helps push the remaining liquid out of the tank to where it is needed. This process eliminates the need for external compressors, relying on the natural properties of the gas within the tank to generate pressure.

Components:

The self-pressurization system typically consists of several key components:

Heater: Used to heat the liquid gas and convert part of it into gas form.
Piping and Valve System: Controls the flow of gas and regulates the internal pressure of the tank.
Pressure Controller: Monitors and maintains the internal pressure within a set range, ensuring safety by preventing over-pressurization or low pressure.

Advantages:

Automated Pressure Regulation: By automatically adjusting pressure through the gasification process, the system ensures a continuous and stable gas supply without the need for manual intervention or additional equipment.
Energy-Efficient: It reduces energy consumption and operational costs by using the liquefied gas within the tank to self-pressurize.
Easy Operation: The system is highly integrated, making it simple to operate and easy to maintain.

The self-pressurization system ensures the safe and efficient storage and usage of liquid oxygen, nitrogen, and argon, making it indispensable in industries such as manufacturing and medical supply chains.
