Column Structured Packing Rating

Details for an existing structured packing in a column section are entered in this window. See Structured Packing Calculations for more information.

Usage

From the Column Tray and Packing Hydraulics Window, define a column section in the table, select Structured Packing as the Internals and select the Rating option in the Calculation Type drop-down list box.

Push the corresponding Enter Data button to enter information for the selected column section.

Manufacturer

Currently, Sulzer and Koch-Glitsch, LP are supported as packing manufacturers.

The RATEFRAC algorithm supports only KOCH-GLITSCH packings (i.e., Sulzer packings are not supported).

Packing Type

Select the required type of packing from the drop-down list. See Structured Packing Types for details of the available packings.

Sulzer no longer supports the packing types OPTIFLOW C.36, KERAPAK, and MELLADUR 250.Y/350.Y/450.Y. And these packing types are not supported in PRO/II.

For RATEFRAC, select the desired KOCH-GLITSCH packing type (Sulzer packings are not supported).

Packing Height

You must enter either the HETP (Height Equivalent to a Theoretical Plate) or the Height of the packed section.

Column Diameter

The diameter of the packed section of the column is required.

Perform Tray Structured Packing Rating Calculations

Select the desired Tray Structured Packing Rating Calculation option by clicking on the appropriate radio button. Normally, packing rating calculations are performed to update the column pressure profile to the calculated tray pressure drops and re-calculate the column with the new profile. See Packing Rating/Sizing at Output or Calculation Time for description of the options.

Click RATEFRAC options ... to pop up Column - RATEFRAC Packing Options dialog box.
