Problems with the final stage of the booster in the distillation tower
Thread Content
The final stage of the booster enters the distillation tower. During this process, the air first enters the main heat exchanger, turning the air into liquid air. The liquid air then enters the gas-liquid separator, and then enters the distillation tower in two separate ways: gas and liquid. My question is that I heard that the gas-liquid separator is an empty shell container with nothing inside. It seems to act as a pressure expander, raising the boiling point and causing part of the liquid to vaporize? Please let me know if this is the case specifically.
There are also many structures of gas-liquid separators. Common ones are empty cylindrical containers. principle: 1. The gas enters tangentially and rotates at high speed. Under the action of centrifugal force, the gas and liquid are separated. Liquid flows downward by its own weight, and gas rises. 2. After the volume increases, the pressure decreases, which lowers the boiling point of the liquid, and part of the liquid vaporizes, causing the liquid to be supercooled.
After the liquid air is throttled, it is usually in a gas-liquid two-phase state. The role of the gas-liquid separator at this time is to separate the two phases.
