With maximizing the reflux at the top of column, a situation arises called 'inverted cone-type liquid loading' which is said to be undesired. I would like to know the effect of such a situation and how to overcome it.
I found this book online, I hope it helps.

Thank you Karim Maraqa!
I have this book, and I would like to more about the query I have asked.
The inverted cone type liquid loading occurs when reflux ratio is increased to a great extent resulting in a very low flow rate of top product stream. This may occur due to excessive condensing of overhead vapour stream. The pool of liquid under this condition begins to accumulate on the tray and can eventually lead to "downcomer choking/flooding" and even "weeping" and affects the column separation performance.
