Sulzer's MellapakEvo maximizes vapor-liquid interaction and improves liquid distribution
As industry demands grew for solutions offering higher capacity and efficiency, Sulzer responded in 1999 with its structured packing MellapakPlus. This new packing generation featured an enhanced corrugation profile, reducing liquid holdup at interfaces between packing elements and significantly boosting column capacity. It set new performance standards and was followed just four years later in 2003 with the introduction of the gauze packing, BXPlus, which applied similar advancements to achieve minimum pressure drop in the typical operating range of gauze packing.
Since then, additional models were added to the MellapakPlus packing family, and Sulzer developed new packing types responding to specific customer needs.
The latest milestone in this evolutionary journey was the launch of Sulzer's next generation structured packing MellapakEvo in 2024. With features designed to maximize vapor-liquid interaction and improve liquid distribution, the packing delivers up to 40% higher efficiency and 20% greater capacity than its predecessor, MellapakPlus. It requires decades of development in structured packing technology to deliver significant benefits in terms of energy savings, operational cost reduction and environmental impact.
The new Sulzer MellapakEvoTM structured packing, in combination with advanced MellaTechTM column internals, delivers unparalleled performance improvement for your columns. Verified at an independent testing facility, this latest mass transfer component technology is proven to enhance column performance in both capacity and efficiency.
