Abstract
A process vessel (2) is for achieving contact between at least one fluid passing through the vessel (2) and a packing material contained therein. The process vessel (2) has a peripheral wall (8) disposed around a longitudinal axis, an inlet for permitting entry of fluid into the vessel and an outlet for permitting the exit of fluid from the vessel. A redistributor (4) is located within the vessel (2) and the redistributor (4) follows a locus (3) which extends around the inside surface (10) of the peripheral wall (8). The locus (3) is neither perpendicular or parallel to the longitudinal axis and is preferably spiral or helical.
Claims17
A process vessel for achieving contact between at least one fluid passing through the vessel and a packing material contained therein, the process vessel comprising a peripheral wall disposed around a longitudinal axis and having an inlet for permitting entry of fluid into the vessel and an outlet for permitting exit of fluid from the vessel, the vessel including a redistributor connected to the inside surface of the peripheral wall, and in which the locus of the connection between the redistributor and the peripheral wall is neither perpendicular nor parallel to the longitudinal axis,
- wherein, on any plane drawn at a right angle to the longitudinal axis, a cross-sectional area of the redistributor on the plane is less than 5% of a cross-sectional area of the process vessel on the plane.
A process vessel according to claim 13 or claim 17, wherein the diverter is in the form of a ledge.
