Does the feed location in the distillation tower have an impact on production?

It will have an impact. It should be at the position where the component concentrations are closest.

It will have an impact; I agree with what was said on the second floor

Reply 1# 244898809: The conditions at the feed location vary; if the number of tray layers remains unchanged, the value of q will change, which in turn directly affects the relationship between the upward flow of gas and the downward flow of liquid in the distillation and stripping sections of the tower. When a cold liquid is fed, q is greater than 1.

An inappropriate setting of the feed plate will affect both the composition of the distillate and that of the residue in the reactor. The feed position is too high, resulting in an increased content of non-volatile components at the top of the tower ； The feed position is too low, resulting in an increased content of light components in the residue at the bottom of the tower. However, when the position of the feed plate changes little, and since tower operation has a certain degree of flexibility (with varying degrees of flexibility among different trays), adjusting the feeding conditions accordingly based on the feed plate position can improve the composition of the materials at the bottom and top of the tower. You need to figure this out through practice, but you should have a certain distillation mathematical model in mind before making adjustments. When the feed composition differs significantly from the original design, the position of the feed plate should be adjusted promptly.

Of course it has an impact. Directly, the number of trays in the distillation section and the stripping section changes significantly, which affects the quality of the product obtained from the top of the tower. Additionally, the feed temperature and composition also play a significant role.
