High performance packing for thermal mass exchange
BSH packings combine the essential features and properties of sheet metal packings and fabric packings in one packing type. The patented surface structure is an outstanding characteristic of the BSH packing. It consists of rhomboidal openings with alternatively crimped edges. This structure results in an exceptional and uniform wetting of smallest as well as large liquid loads. Turbulences caused by the crimped edges of the openings create a continuous mixing of the liquid film on the packing surface.
Properties:
Large capacities and flexibility
Good wettability and therefore optimum contact areas between gas and liquid
High separation performance, close to capacity limits
Liquid loads 0.02 to more than 150 m³/(m² h)
Low pressure drop
Solutions for every separation problem through variable, specific surfaces
Applications:
Vacuum columns
Atmospheric columns
Absorption
Natural gas drying
Refinery columns
Petrochemical columns
Waste water strippers
Separation columns for chemical industry
