An absorber or desorber contains a layer () for a structured packing which has corrugations, wherein a plurality of open channels () is formed by the corrugations, wherein the channels include a first corrugation valley (), a first corrugation peak () and a second corrugation peak (). The first corrugation peak () and the second corrugation peak () bound the first corrugation valley (), wherein the first and second corrugation peaks have a first apex () and a second apex (). An indentation () extending in the direction of the first apex () is formed on the first apex () of the first corrugation peak (). The first corrugation valley () has a valley bottom (), wherein the normal spacing () of at least one point of the indentation () from the valley bottom () of the corrugation valley () is smaller than the normal spacing () of the first apex () from the valley bottom () of the corrugation valley ().

Mass transfer apparatus having a structured packing

The valve cover has a pair of tabs at the ends that are inserted into end sections of an orifice in the tray deck. The tabs of the valve cover abut against the underside of the tray deck while a pair of sloped portions of the valve cover rest on the top side of the tray deck in order to hold the valve cover in place.
