Liquid level issue in the crude argon column condenser
Thread Content
After the amount of argon removed during the processing process is reduced by a quarter, the other valves in the crude argon tower remain unchanged. Does the liquid level in the crude argon condenser rise or fall? Also, does the argon content in the argon fraction affect the level of the liquid in the crude argon condenser?
I don’t know why you want to reduce this by 1/4? With the valves in the crude argon column not moving (and self-regulation also not working), and the liquid level in the condenser remaining unchanged, all you can do is wait for a \"nitrogen plug\" to form. The liquid level in the crude argon condenser refers to the liquid-air side; you need to distinguish between what is primary and what is secondary in this regard. Influence, and being influenced. Guess what your question is – it’s probably asking whether the argon production capacity can still be maintained if the plant operates at reduced load. My answer is “no”. This variable-load production is feasible within a certain range; it is not possible outside that range. It’s just a speculative explanation.
The liquid-air inlet and outlet valves of our crude argon condenser are all in manual mode. The amount of process argon decreases; other valves remain unchanged. As a result, the heat load on the crude argon condenser drops, which leads to a reduction in the amount of liquid air that evaporates. Since the valve controlling the flow of liquid air into the condenser stays the same, the amount of liquid air entering the condenser does not change. This causes the liquid level in the condenser to rise. As the liquid level rises, the static pressure at the bottom of the liquid increases, leading to an increase in the amount of liquid air that flows back to the main tower. When a balance is reached between the liquid and gas phases entering and leaving the condenser, a new equilibrium is established.
