Why isn’t anyone answering? I’m a beginner, so my questions might not be professional, but I really want to understand it Could someone please give me some advice? Thank you!

Your questions could fill an entire book; I suggest buying a book titled \"Questions and Answers for Oxygen Technicians\" to read.

These issues were all thought about before taking any action; in reality, after carrying out the operation, many problems are adjusted on the spot according to the conditions at that time, rather than being imagined here in advance. Determining how many controls are necessary requires design parameters, while figuring out how to adjust them needs a flowchart; normally, the low-pressure board is used for gas redirection. In fact, we have experienced a situation with high-pressure pilot gas, which was handled by the commissioning engineers from the design manufacturer; it is not recommended to operate the high-pressure air throttle valve without sufficient experience. The opening degree of this valve is adjusted based on the operating conditions of the expander, as specified in the relevant procedures. . Does the air entering your expander come from the booster or from the pressurization section of the expander? For the process that comes directly from the booster, the references are: the temperature before the expander, as well as the flow rate of processed gas at the expander and in the boosting section; in other words, the loads on both sides, which determine the shaft temperature and vibration levels, and adjustments are made accordingly. Of course, when the hot tower and cold tower are in operation, and the expander is functioning properly, it is preferable to increase the expansion ratio of the expander to boost the cooling capacity. How to control the temperature in front of the expander when starting it? How much to control? The control level depends on how the cooling capacity for the process is provided and what the temperature before the machine should be set at Control is achieved by adjusting the flow of hot and cold air through the high-pressure plate exchanger. Purification is adjusted while liquid accumulates: both the upper and lower towers are packed towers; in the cold tower, the throttle valve is gradually closed as the temperature drops, so almost no purification is required.

Thank you, may a kind person have a safe life.

This requires considering the process involved; the original poster can provide a brief description of your process so that the analysis can be conducted more effectively. Pure theory alone cannot solve the problem, and it is also necessary to try it out in actual operations.

The process is different, and the operations involved are also somewhat distinct. The issues you mentioned are numerous, just as was said above. If you want to understand them in detail, you should talk face-to-face with your experienced instructors and then try it out in practice; that way you will know everything.

What does this mean? What on earth are you doing?

How are the high-pressure throttled air flow and the expander flow allocated? Only then can the temperature in front of the expander be reduced quickly, as this temperature serves as a reference for heat exchange in the system!

Before driving, try not to operate the high-pressure throttle valve. For applications that require significant heat exchange cooling, the airflow to the high-pressure plate-type cooling source should be adjusted to its maximum level, thereby reducing the temperature at the inlet of the expander.
