a tray plate with substantially circular circumference and having top and bottom surfaces, which tray plate is provided with
passages for gas between the bottom and the top surface, and on which tray plate two semi-circular tray sections are defined
by a virtual diametrical line of the tray plate; and
a total of three downcomers for guiding liquid from the top surface of the tray plate to below the tray, each downcomer extending
from an inlet opening arranged in the tray plate to a downcomer outlet opening below the tray,
