What determines the location of the tower feed inlet?
Determined based on the working principle of the tower and the properties of the raw materials
The constant-precision distillation tower has three feed inlets. Installed at different heights on the tower. In production, the appropriate feed inlet should be selected based on the specific circumstances, and adjustments may be necessary. As defined by the optimal location of the feed plate, for a distillation column fed at or near the bubble point, the selection of the feed inlet is determined based on ensuring that the composition of the feed matches that of the feed plate. Generally speaking, when the proportion of volatile components in the mixture to be separated increases, a feed port located at a higher position is chosen; the feed port is adjusted accordingly when the feeding conditions change. When the feed temperature decreases, a feed port at a higher position is used ； Conversely, use a feed port at a lower position.
Here’s some material from Northeast Forestry University. “Determination of the Optimal Location of the Feed Port in Plate Distillation Columns and Calculation of the Theoretical Number of Plates” – you can look for it online. If you can’t find it, give me an email address and I’ll send it to you.
Upstairs, could you pass me a copy? I really need it too; I’m extremely grateful. My email address is 55456742@qq.com. Thank you again!
I want one too, please send me one. Thank you! My email address is likewen4310@163.com
Determined based on the properties of the raw materials and the feeding method!
It exists in the principles of chemical engineering; it’s one of the most basic calculations. The theoretical number of theoretical plates is determined based on the properties of the raw materials. This post was last edited by brainandrain on 2009-4-12 at 20:35
Could you please send one to me on the 4th floor as well at zhangcp_2009@163.com? Thank you! :P
It should be determined based on the data from process calculations. Generally, the diameter and location of the nozzles in a tower are provided by the process calculation package
The location of the feed inlet needs to be determined based on the distillation section, the properties of the feed material, and the state of the feed. I remember that in school, the teacher taught us how to use Aspen for such design tasks.

It should be determined based on the degree of distillation required, as to where to feed the material
The tower feed inlet location can be determined based on the composition of the raw materials, as well as through calculations related to the separation process. The principle is that it is best for the feed composition to be identical to the actual concentration composition inside the tower, in order to minimize the disturbance caused by the feed on the distillation process; hence, the feed plate is also known as a sensitive plate
