Title: A PACKING ELEMENT METHOD TO PRODUCE IT AND A COLUMN OR REACTOR COMPRISING SAID ELEMENT
Abstract:
A packing element (1) for use in mass and/or heat transfer processes through which at least one liquid may flow, wherein the packing element (1): has an outer surface (2) comprising three or more outer arched rib elements (21) and two outer connecting edge elements (22), optionally has an inner surface (3) comprising optional inner arched rib elements (31), wherein the element 1 is substantially spherical or substantially ellipsoidal, and wherein the outer connecting edge elements (22) and the outer arched rib elements (21) and optional inner arched rib elements (31) are embodied such that the total projected area (4) of the packing element (1) when viewed in any direction (7), preferably a radial direction (5) or optional axial direction (6), is partially open due to the presence of an open projected area (41), wherein it is open to an extent that ranges from about 15 to about 50, preferably about 17 to about 40, more preferably about 18 to about 35, most preferably about 20 to about 30 % of the total projected area (4). The invention further relates to a method for producing said element (1). The present invention further relates also to a column or reactor comprising a bed of said elements (1), a method to prepare said bed, and the use of the element (1) or column or reactor in a mass transfer and/or heat transfer process and/or in a chemical reaction.
