I’d like to ask about the requirements for pursuing a craft-related career

The size of the reflux tank at the top of the tower is determined based on time factors. What about the other tanks, such as the buffer tanks and the separation tanks? By the way, the liquid level is determined by the volume of liquid present. Are there any standards regarding the interlocks on the instruments and things like that? Or are these rules derived from books? And which book contains those standards? Thank you all, Happy New Year!
It seems that no book or standard yet provides a definitive answer; judgments and calculations need to be made based on the specific manufacturing process in which these devices or instruments are used. Regarding the process calculations for containers, I recommend an old book titled \"Process Design Data for Refining Equipment: Process Design of Containers and Liquid-Liquid Mixers\" (an electronic version of it is available on this forum); I personally think it’s worth studying*.
What about the level gauge? How is the height determined? And how is it decided for some device ports whether they should be connected at that height at a tangent point or directly inserted? You know?
It’s really hard for me to answer you. Simply put, the liquid level height of a level gauge depends on the process requirements for the measured liquid level, such as meeting the maximum, normal, and minimum levels. As for the specific choice, it remains as I mentioned earlier: it depends on the manufacturing process.
I think the first thing is to ensure that the volume of the container meets the requirements for use. For a reflux tank at the top of a tower, its main purpose is the separation of gas, liquid, and water; it is crucial to ensure an adequate settling time for water as well as a proper separation time for gas. On this basis, it is also necessary to guarantee that the container does not become empty, overfilled, or overflow while in normal use. The design approach for the remaining containers should be similar as well; the focus of the design should primarily depend on the different functions of each container.
