SplitPak and SplitPak Plus packing

SplitPak (Mellapak until 2023) is the most widely used structured packing worldwide.

SplitPak Plus (MellapakPlus™ until 2023) is the latest-generation structured packing with increased capacity.

Thanks to its original improved geometry, compared with conventional SplitPak structured packing, the pressure drop is significantly reduced and maximum capacity can be increased by 25–30%.

The close similarity between SplitPak Plus and SplitPak packing enables successful use of a range of well-known and reliable column internals. The internals help accommodate the increased gas load corresponding to the potential capacity of SplitPak Plus.

Preferred operating conditions:

• From vacuum to medium pressure

• High pressure in certain processes

• Capacity increase for existing tray and packed columns

Fields of Application

basic chemicals
ethylbenzene/styrene
petrochemicals

Advantages

Universal packing type
Suitable for a wide range of applications—from low to very high liquid loads, from vacuum to moderate pressure for distillation, and at high pressure for absorption and stripping systems
Available in a wide range of stainless steels, alloys and thermoplastics
Unique geometry; manufactured in five sizes differing in specific surface area
At the interface between two packing elements, the gas flow changes direction smoothly
At the edge of the element, the gas flow is directed almost parallel to the vertical axis of the column. As a result, gas velocity is reduced by approximately 25% compared with the velocity inside the packing element
