Title
(EN) Internal members for mass transfer columns
Abstract
(EN)

Internal members or baffles for material exchange columns have at least one packing bed. The packing bed has at least one first packing block and at least one correction element associated with the first packing block. The first packing block and its associated correction element produce different final distributions of liquid or systematic maldistributions. The systematic maldistribution in the liquid phase caused by the first packing block is largely corrected by the systematic maldistribution of the associated correction element. Such an arrangement makes possible enhanced separation efficiency or higher packing beds.
