I need advice from an expert!

Regarding the operation of a distillation column, how do the various operating parameters within the column change when the feed composition varies? Why? How does it need to be adjusted?
Your question is too general; it’s not clear how the components change – for example, do they become lighter or heavier?
Check whether there are more heavy components or light components in the feed. As the amount increases, the temperature gradient grows larger, and the opening controlled by the top pressure becomes smaller. Adjust to increase the steam volume and reduce the reflux. Conversely, there are more light components.
This question is too unprofessional; it would be better to be more specific. You can ask experienced colleagues for basic operations; don’t you have a mentor?
The poster’s question is equivalent to asking about all the issues related to distillation tuning; in other words, it’s as if no question was asked at all! The temperature, pressure, and reflux control of distillation towers need to be handled on a case-by-case basis. If you want to learn more about this, you can contact me privately; we specialize in the design and manufacturing of distillation towers, and I’m sure I can help answer your questions!
What happens if it gets lighter? What happens if it gets heavier? What changes will occur in operations inside the tower? Why has this change taken place? How should it be adjusted? Thank you!
