A fractionation tray for use in a process column. The fractionation tray is of a type where a first fluid flows downwardly from a downcomer onto the fractionation tray and across the fractionation tray in a first direction. A second fluid flows upwardly through the fractionation tray for interaction with the first fluid. The fractionation tray includes an upper tray section, a lower tray section that is operable to removably engage the upper tray section, a joint region which includes an area of overlap between the upper tray section and the lower tray section. The joint region allows passage of the second fluid therethrough.
