Abstract
The invention provides novel mass transfer elements with a corrugated body structure and having ends turned back in a direction opposed to the curves of the corrugations such that the ends are turned towards one another. These elements are particularly effective as random dumped packing for mass transfer towers, providing a combination of high surface area and low pressure drop.
