Internal compression fluid purification procedure
Thread Content
Gentlemen: I’m seeking the procedure for purifying fluid accumulation due to internal compression! Note: Liquid oxygen is pressurized and then vaporized in a vaporizer before entering the plate-type reactor, which is slightly different from the commonly used internal compression process! Learn from the methods used by other sea friends!
There’s no difference; they’re all similar. Liquid oxygen is pressurized by a liquid oxygen pump and then sent to the liquid oxygen evaporator, where it exchanges heat with pressurized air before entering the main exchanger. After reheating, pressurized oxygen is obtained. Many internal compression processes work in this way. Learn from the operation method.

Question: After your liquid oxygen is pressurized by a liquid oxygen pump and then sent to the liquid oxygen evaporator where it exchanges heat with pressurized air, why does it still need to go to the plate heat exchanger? ?
It should be liquid oxygen that, after being pressurized by a high-pressure liquid oxygen pump, enters a high-pressure heat exchanger (where it exchanges heat with high-pressure air), is reheated, and then enters a pressure regulating device.
Liquid oxygen exchanges heat with pressurized air to become oxygen, which then goes to the main exchanger for further reheating; pressurized oxygen is obtained upon exiting the cold box.
It’s as if the plate cooler has been divided into two sections… the bottom part vaporizes the liquid, while the upper part continues to reheat it
You mean the external compression process of Hangyang’s 60,000 model, right? Liquid oxygen enters the liquid oxygen self-pressurizing evaporator where it exchanges heat with air (air coming in via plates); the air releases heat and turns into liquid air, which then enters the lower tower. Liquid oxygen absorbs heat, causing changes in the gas oxygen. ) to obtain oxygen. Oxygen enters the main heat exchanger to exchange heat with air, resulting in oxygen at room temperature. Then the oxygen pressure is increased.
No, we use an internal compression process; there is no oxygen compressor, and liquid oxygen pumps are used for pressurization.
Liquid oxygen exchanges heat with pressurized air to become oxygen, which then goes to the main exchanger for further reheating; pressurized oxygen is obtained upon exiting the cold box. 4 H/d. ~0 That’s what you wrote; after heat exchange with air, liquid oxygen becomes oxygen. So why go to the main heat exchanger for further reheating? Please provide some flowcharts to study*. Thank you...... Email: 64304289@qq.com
After being pressurized by a high-pressure liquid oxygen pump, the liquid oxygen enters a high-pressure heat exchanger (where it exchanges heat with high-pressure air), is reheated, and then enters a pressure regulating device. This should be a relatively common case of internal compression
