Normal operation of the tower

It should be the temperature gradient, concentration gradient, and the site of mass and heat transfer, that is, the tray

Haiyou: If it’s a distillation tower, there are many factors that affect distillation; the topic raised by the original poster is a bit too broad. Factors that typically affect distillation include the design of the distillation tower itself, whether the trays or packing and internal components are appropriate, the design of the reboiler and condenser, the heat source used for heating and the cooling source used for condensation, the vapor and liquid load on the tower, the composition of the feed, the reflux ratio, the requirements regarding the conditions at the bottom and top of the tower, the desired separation efficiency, as well as the instrumentation and automation systems in place. All of these elements have an impact on the operation of distillation.

If it’s a packed tower, the key factors, in my opinion, are the gas velocity, the flow rate of the liquid sprayed from the top, and the liquid distribution density.

Top condensate volume, bottom heater heat input, feed rate, and condition.

This topic is really too general. There are many factors that affect tower operation; the “three key aspects” seem insufficient to cover them all. What you mentioned—\"overflowing, leakage, and mist entrainment\"—can be categorized as \"fluid dynamic properties.\" If we have to mention the \"three major\" factors, we can consider the temperature distribution within the tower (especially the temperature in the sensitive zone), the operating pressure of the tower, and the liquid level at the bottom of the tower. This is a bit forced as well; I’m not sure what the teacher’s answer is. Once the teacher reveals it, it will definitely be posted here for everyone to learn from.*

It is related to flooding, the air volume entering the tower, the packing layer or trays, and the circulation volume flowing in counterflow to the air entering the tower

It’s indeed too general. Under normal operating conditions, I think the relevant parameters should include: 1) the composition, flow rate, temperature, and other aspects of the feed; 2) the heating condition of the reboiler; 3) the amount of reflux, among other parameters. I hope the original poster can provide more details so that we can give better answers, hehe

The key is to be more detailed in the operations, okay?

Please refer to Section 7 of \"Principles of Chemical Engineering\" on distillation – \"Operational calculations for two-component distillation and factors affecting operation.\" There is a key factor that influences distillation operations: 1. Maintaining material balance between the inlet and outlet of the distillation unit is a necessary condition for stable operation; 2. The impact of reflux at the top of the tower; 3. The influence of feed composition and feed heat conditions. I believe these are the three factors in question

In the case of a distillation tower, there are many factors that affect distillation. Factors that typically affect distillation include the specifications and dimensions of the distillation tower itself, whether the trays or packing and internal components are appropriate, the type of reboiler and its heat exchange area, the type of condenser, the heating source, the cooling source, the vapor and liquid load on the tower, the composition of the feed, the reflux ratio, the requirements regarding the composition at the bottom and top of the tower, the desired separation efficiency, as well as the instrumentation and automation systems in use. All these elements have a significant impact on the operation of distillation. In short, the best approach is to conduct a specific analysis of each particular problem and address it within the process of reproduction.
