UNIDENSETM

Catalyst Loading Process:
Improve the quality of primary reformer catalyst loading with UNIDENSETM technology!

Sock loading method (100mm tube) UNIDENSE technology (100mm tube)

  • Faster reformer loading
  • No presocking of catalyst
  • No vibration of tubes
  • Uniform pressure drop
  • Less waste of catalyst
  • No bridging of extra voids
  • Less tendency of hot spots
  • Less settling of catalyst
  • High uniform density
  • Lower tube wall temperature
  • Prolonged tube life
  • Increased reformer capacity

Cat Tech (as a licensee of Norsk Hydro) if offering this catalyst loading technology for the filling of primary reformer tubes in ammonia, methanol, hydrogen and other reformer-based plants.

  • UNIDENSETM is a simple and fast loading technology applicable to tube sizes 3" to 10" in internal diameter.
  • UNIDENSETM requires no pre-socking of catalyst and no vibration of reformer tubes.
  • UNIDENSETM combines a high-quality loading with fast loading technology. Reloading of tubes is normally avoided, reducing catalyst waste.
  • UNIDENSETM principle: Catalyst is filled into the tube along a loading rope which is gradually pulled from the tube as the catalyst layer builds. Brushes along the length of the loading rope reduce the speed of the falling catalyst so that breakage is avoided. This results in loading without bridges and extra voids of catalyst particles, hence there is no need for vibration.
  • UNIDENSETM technology, the loading time of a primary reformer can be substantially reduced while maintaining a high-quality loading. Typical loading time for 4" tubes is 8 minutes.
  • UNIDENSETM ensures that pressure drop variation of the tubes will be within a narrow range, assuring even gas flow in the tubes. The density will normally be higher than with the loading sock method, resulting in slightly increased - but more even - pressure drop, due to better packing. Since there are no extra voids, further settling of the catalyst - and thus pressure drop increase - will be minimal.
  • UNIDENSETM gives high uniform density along the full length of the tube, providing less tendency to hot spots and contributing to lower tube wall temperatures and prolonged tube life.
  • UNIDENSETM has been used for the unloading of all common catalyst types and sizes. Reformer tube designs with varying internal diameter, narrow or wide top section, have successfully been loaded.
