What is Structured Packing?

Structured packing is an advanced column internals material specifically engineered to maximize efficiency in chemical processing separation towers. Used in applications like distillation, absorption, and stripping, structured packing creates an organized surface area ideal for gas-liquid contact and mass transfer.

Types of Structured Packing: Our extensive range includes Metal Structured Packing, Ceramic Structured Packing, and Plastic Structured Packing, each tailored to meet specific process requirements regarding corrosion resistance, temperature, and cost.

Why Choose Structured Packing?

Implement structured packing for superior performance in demanding applications, including processes requiring:

  • A large number of theoretical stages
