Random Packing Characteristics

The Packing Factor is required for the packing calculations. You may enter a value directly, or select a standard Norton or KOCH-GLITSCH Type and Packing Size. Selecting a pre-defined type and size automatically loads the appropriate packing factor and other pre-defined data.

Manufacturer

If the selection is Norton or KOCH-GLITSCH, you may select from the predefined packing Types.

Although Koch-Glitsch, LP now owns the Norton packings, PRO/II continues to access properties of former Norton packings by grouping them under Norton as the manufacturer.  Otherwise, when the packing manufacturer is Unspecified, you must supply the Packing Factor.

For RATEFRAC, you may select from the predefined KOCH-GLITSCH packing types. (These do not include the former Norton packings.)

Type

You may select from the available Norton or KOCH-GLITSCH packings. If you select a standard Packing Size, the appropriate Packing Factor is entered automatically.

For RATEFRAC, you may select from the available KOCH-GLITSCH packings. (These do not include the former Norton packings.)

Packing Size

Select or enter the required size. This is required if the HETP is to be calculated by the program. For a Norton or KOCH-GLITSCH packing, you may choose from the predefined list for the selected packing Type as long as the dimensional units are inches or mm.

Packing Factor

If you select a standard Packing Size for a Norton or KOCH-GLITSCH packing, the appropriate factor is entered automatically. Packing factor denotes area per unit volume of the packing material. This value is used in the pressure drop calculation of the column. A higher packing factor correlates to a higher pressure drop in the column.

Norton Company, Norton packings, and Norton method are wholly owned by Koch-Glitsch, LP. PRO/II continues to differentiate former Norton packings from other KOCH-GLITSCH packings by accessing them using Norton as the manufacturer.
