Structured packings

Structured packing is one of our core abilities. Over 50 years of experience in development, design, and production of this type of packing makes us your best partner to find the optimum solution for your application.

Mellapak™ structured packing
Mellapak™ and MellapakPlus™
Mellapak is the most widely used structured packing worldwide. MellapakPlus™ is the latest generation of structured packing. With the enhancement of the geometric structure of conventional Mellapak™, the pressure drop is much lower and the maximum capacity can be extended by 50% compared to Mellapak™.

MellapakCC™
We have developed a new structured packing for absorbing carbon dioxide more efficiently from flue gas streams of fossil-fueled power plants. Sulzer MellapakCC significantly reduces the column size and the pressure drop across the CO2 absorber, thus reducing capital and operational expenses.
Details of a structured packing: Hybrid Gauze Packing AYPlus™ DC
Hybrid gauze packing AYPlus™ DC
AYPlus™ DC is based on a newly developed hybrid gauze material combination and the geometry of MellapakPlusTM 252.Y. AYPlus DC has a distinctly increased separation efficiency compared to MellapakPlus 252.Y, in particular at low liquid loads and with aqueous systems.

Gauze packings
BX gauze packing has been successfully employed in the industry for over 50 years, allowing difficult separation tasks to be accomplished. CY packing was developed for separations that require even a larger number of theoretical stages. BXPlus and CYPlus are the latest generation of gauze packings and offer the same efficiency as BX respectively CY with a 20% lower pressure drop.
Laboratory packings in small diameter
Laboratory packings
For small laboratory column diameters we can offer you specially designed packing types for a preliminary assessment of a separation task. They offer you the highest number of theoretical stages while keeping a small pressure drop.

Mellacarbon™, Mellapak™ & MellapakPlus™ - Packings for corrosive systems
In cases where corrosion is a main issue and metal packings are not an option, we can offer you structured packings made of carbon and of different thermoplastic materials.

Structured grid packings - Mellagrid, Nutter Grid, F-Grid
Grids are developed for severe services that are susceptible to fouling, erosion, coking, and high solids content. Grids are installed in rigid modules stacked in successive layers with a fixed orientation, thus minimizing the overall pressure drop while simultaneously increasing tower efficiency.
