There is already a distillation column; as the pressure in this column increases, how do the concentration of the light components at the top of the column and the amount of product collected from there change?

I have a question: Given an existing distillation column, if the operating pressure of this column is increased to establish a new equilibrium, how do the concentration of the light components at the top of the column and the amount of product collected from there change? Personally, I think that increasing the operating pressure reduces the relative volatility between the components, thereby increasing the difficulty of separation. According to the P-x(y) phase diagram, this corresponds to a position closer to the diagonal line; however, it seems that the feed line should shift counterclockwise, and I’m not sure how to analyze the rest of it. Could the expert help me analyze this theoretically?
Increasing the operating pressure reduces the relative volatility between the components, making separation more difficult, decreasing the processing capacity, raising the concentration of the light components at the top of the tower, and reducing the amount of product obtained from the top of the tower.
Increasing the operating pressure can boost the processing capacity
What is the purpose of doing this?
I want to conduct a theoretical analysis to see what the impacts would be
Increasing the pressure results in less distillate at the top of the tower, while a larger amount of distillate is obtained. . .
I hope everyone will conduct theoretical analysis and not just state the results; thank you
