Abstract
Mass transfer elements with an essentially four-lobed cylindrical configuration are particularly effective random dumped packing elements for mass transfer towers, providing a combination of high surface area and low pressure drop.
Claims6
A mass transfer element having a generally deformed cylindrical structure in which the cylinder wall has been inwardly deformed at opposed ends of mutually perpendicular diameters to provide a cross-section with external lobes, in which the ratio of the lengths of the mutually perpendicular diameters after said deformation is from about 2:1 to about 4:1.
