Leading expert for distillation technologies

Sulzer Chemtech is a leading expert and solutions provider for a range of distillation technologies. Our product portfolio comprises a unique and extensive range of top-performance, state-of-the-art column internals.

  • Structured packing (for example, MellapakPlus and BXPlus gauze packing) 
  • Random packing 
  • Trays (conventional, high performance and cartridge trays) 
  • Column internals (for example, distributors and collectors) 
  • Vapor-liquid and liquid-liquid phase separators (such as KnitMesh mist eliminators and MellachevronTM vane packs)

We are continuously improving our process solutions to meet your complex distillation challenges. We also offer you combinations with our other state-of-the-art process technologies.


We offer either a basic engineering package including key equipment such as column shells, internals, heat exchangers, and decanters, or a complete, often skid-mounted unit including process control and start-up support services.
