Regarding the load performance graph

How to use the load performance diagram of a distillation column to guide distillation operations, and what effects changes in conditions such as pressure, reflux ratio, feed conditions, and the number of trays have on those five curves
The words “tray” should be added in front of the load performance graph. It is calculated based on the tray structure and physical property conditions. It is independent of operating conditions such as the reflux ratio. There are five lines in total. Once the load performance diagram is prepared, the operating point of the tower, that is, the intersection point of the vapor and liquid flow rates within the tower, should lie within the closed area enclosed by the five lines. It is preferable that this point not be too close to any of the boundary lines, as fluctuations in the vapor and liquid flow rates can otherwise lead to abnormal operation of the tower.
It’s a good post, but there are few replies :(
