What are the self-pressurization methods and approaches used in the large-scale air separation storage tank areas of all experts?

It was originally a water bath type; the flow rate was too high, which caused a burst that resulted in dozens of meters of piping disappearing. Now it has been replaced with a fin-type design

Improper operation leads to unreasonable settings. Reasons for the accident: First, no temperature monitoring was installed at the bottom of the heat exchanger where water is present ； II. No monitoring and analysis of the water-side surface of the heat exchanger was carried out ； III. For oxygen pipelines using carbon steel tubes, overloading can cause liquid to flow out of the heat exchanger, leading to freezing and cracking of the pipelines ； These three situations are the main causes of overpressure rupture. What are the self-pressurization methods and approaches for large air separation storage tank areas? Answer: The liquid is delivered to the vaporizer by means of its potential energy. The vaporizer exchanges heat with the atmosphere (through convection), causing the liquid to vaporize and generating the required pressure. Some of this pressure returns to the storage tank as vapor pressure in that tank, which in turn adds to the liquid’s potential energy, allowing more liquid to be delivered to the vaporizer for vaporization. A pressure reducing valve is installed in the line between the carburetor and the return tank to control the amount of liquid entering the carburetor and to regulate the gas output. Furthermore, using an air-type carburetor is a poor choice; it is more suitable for production with low flow rates and high pressures ； Not suitable for production under high volume and low pressure conditions.
