Random Packing

Random packing for mass transfer applications

PunchTech manufactures and supplies random packing for packed columns and towers used in distillation, absorption, stripping, scrubbing and other mass transfer applications.

Packing is selected around the process duty, column geometry, hydraulic requirements, material specification and associated internal arrangement.

Packing Selected for the Service

Geometry, size & material drive performance

Random packing consists of individual packing elements loaded into a supported packed bed. The geometry, size and material of the packing influence how the bed performs across a range of measures.

PunchTech reviews the application before confirming the appropriate manufacturing and supply scope.

Packing influences

  • Available surface area
  • Mass transfer
  • Gas & liquid capacity
  • Pressure drop
  • Liquid distribution
  • Mechanical strength
  • Fouling behavior
  • Packed-bed stability
Random Packing Configurations

Selected to the duty

Subject to PunchTech's verified manufacturing range, requirements may include various metal ring, saddle and high-open-area packing geometries.

Note: specific product names, geometries and sizes should be published only after the available PunchTech range is technically confirmed.

The exact configuration should be selected based on

  • Process duty
  • Gas & liquid loading
  • Column diameter
  • Required efficiency
  • Pressure-drop limitation
  • Fouling tendency
  • Material compatibility
  • Bed depth
  • Mechanical requirements
