Participation earns 4 points of wealth! 10 wealth points as a reward for correct answers or in-depth discussions! :Lol, what does \"drowning the tower\" mean? Answer: During the distillation process, liquid gradually accumulates above a certain tray, eventually filling part of the tower section and obstructing the upward flow of gas. This prevents proper mass and heat transfer between the gas and liquid phases, a condition known as tower flooding. ======================================== ☛【Haichuan Activity Plan】I decide my own questions – I’ll choose the “best answer”! http://bbs.hcbbs.com/thread-1618021-1-1.html (Source: Haichuan Chemical Industry Forum) ☛Sponsors are being sought for the “2016 Haichuan Top 10 Members Selection Contest” http://bbs.hcbbs.com/thread-1628108-1-1.html (Source: Haichuan Chemical Industry Forum) ☛Everyone is welcome to scan the QR code to follow Haichuan’s WeChat official account and download the mobile app: http://bbs.hcbbs.com/attach/data/attachment/forum/201610/13/213618s5iw2kw5z5l6nnwb.jpg

Doctor, you edited away everyone’s topics! Also, the wealth rewards should not be too large. During the weekend when there are fewer people, rewards can be increased! It is best to participate 2 times normally, get 5 correct answers, and engage in in-depth discussions 8-10 times. The specific dimensions are determined based on the level of participation from the various sections. Daily Question: It is recommended to find questions from the existing resource posts in the section, and include the address of those resource posts at the end of the question! In this way, if everyone thinks the topic is good, they can download it to study* It also increased the download of zone resources, boosting the popularity of the zones! Picture of the day: Why not give the answer directly? Instead, the address of my device and my home is provided, so that people can see the question and go to that address link to find the answer! It’s to guide everyone to learn *! Increase the popularity of the section! !
Foaming becomes excessive, with the trays and inside of the tower filled with liquid; this is what is known as tower flooding.
During the distillation process, liquid gradually accumulates above a certain tray, eventually filling part of the tower section and obstructing the upward flow of gas. This prevents proper mass and heat transfer between the gas and liquid phases; this condition is known as tower flooding, or liquid slugging. There are two types: split jet flooding and downcomer flooding. Spray flooding is a type of entrained flooding caused by an excessive gas load, and it is primarily determined by the gas velocity. Weeping in the downcomer is caused by an excessive liquid load, which is primarily determined by the highest clear liquid layer on the tray and represents the upper limit for the liquid load.

Within the distillation column, the liquid phase flows from top to bottom through the downcomers due to gravity; thus, the liquid moves from areas of lower pressure to areas of higher pressure. Therefore, it is necessary for there to be a sufficient height of liquid in the downcomers in order to overcome the pressure drop between the two plates and enable flow. If the flow rate of one of the gas or liquid phases increases, it prevents the liquid in the downcomer from flowing downward properly. As a result, the liquid level in the pipe rises to the top of the overflow weir on the tray, causing the liquid between the two trays to become connected and leading to an accumulation of liquid inside the tower. This phenomenon is known as tower flooding. In addition to degassing and liquid flow rate, factors that affect flooding in a tower include the tray structure, particularly the tray spacing
Answer: During the distillation process, liquid gradually accumulates above a certain tray, eventually filling part of the tower section and obstructing the upward flow of gas. This prevents proper mass and heat transfer between the gas and liquid phases, a condition known as tower flooding.
