The MellapakPlus™ 252.Y plastic packing benefits from the proven features of Sulzer’s MellapakPlus™ product line. At the lower and upper portion of each packing element, the angle of the corrugation gradually approaches vertical, resulting in a s-shape geometry. Due to this modification, the direction of the vapor flow smoothly changes at the interface between two elements. This smoother flow leads to a reduction of the vapor flow velocity and shear forces, resulting in a decreased liquid hold-up at the element transition. The net result is a reduction of pressure drop while providing the same separation efficiency as the previous industry standard, Sulzer Mellapak™ 250.Y PP while keeping the same capacity as the Mellapak™ 250.X PP type.

Therefore, MellapakPlus™ 252.Y plastic packing can be used to replace standard plastic packings and rings and provides higher capacity and efficiency depending on the actual situation.

At the moment MellapakPlus™ 252.Y plastic packing is available from PP. Other plastic types such as PVDF are in preparation.
