Column Internals

Interdistributor Screens 

Packing supports at the bottom of columns are designed to perform two critical functions – support the packing in the column and distribute the vapor uniformly into the packing without causing flooding.

For columns larger than two inches in diameter, our interdistributor screen resting on an 1/4” flange has been found to provide necessary packing support. In columns up to 8” in diameter, an additional support is needed.

These screens ensure good hydraulics throughout the bed height.

Packing Holddown Screens 

Engineered to prevent the bed of packing from being disturbed when bumping occurs in the reboiler or when the column is operated under flooding conditions, these flat, circular screens are placed in the column directly under the top flange. All screens come in standard 10x10x0.025″ mesh.
