Can the tower liquid level be higher than the distillation reboiler outlet?
Thread Content
1. For the teacher, L1A and L1B are the upper and lower ports of the liquid level gauge, and A5 (DN700) is connected to the outlet of the reboiler. The liquid level gauge I have contacted before has not been higher than the outlet of the reboiler. Now the liquid level gauge is higher than the outlet of the reboiler. Can the liquid level of the tower be higher than the reboiler? Is there such a tower in chemical engineering principles? 32% of the liquid level is in the middle of the reboiler outlet, and 51% of the liquid level exceeds the reboiler. 2. Baidu’s definition of flooded tower does not seem to mean that the liquid level in the tower is higher than the reboiler. Is the liquid level allowed to be higher than the reboiler?
See if there is any special structure inside the tower； Otherwise, the general situation is that the liquid level at the bottom of the tower cannot reach the reboiler outlet. The liquid level at the bottom of the tower is displayed, just pay attention to the percentage of the liquid level to the outlet of the reboiler.
After that, there is a mixture of soda and water, and the system will vibrate greatly and become unstable.
This depends on the specific production process requirements. In principle, the larger the gas-liquid contact area, the higher the efficiency. If it is the main condensing evaporator of a cryogenic air separation equipment, the requirement is that it must be fully immersed. (Except shower type). I don’t know what your production medium is like, whether it is related to the physical and chemical properties of the medium, but it is best to follow the equipment operating specifications for control. If the principles of the process need to be discussed, it is best to attach a simplified process flow diagram to facilitate discussion.
