Why is a composite tower used for the stabilizer in crude benzene hydrogenation?

There is mainly a heating tube at the bottom; a plate tower is used there, and the heating tube functions as a reboiler, which facilitates better heat transfer. Packing is used in the upper part to increase the heat exchange area

It is possible to increase the area for mass and heat transfer, thereby preventing excessive amounts of benzene from entering the tower top and causing losses.
