Program Description The PackCol program performs hydraulic design and rating calculations for packed columns and towers. The design basis for new columns can be approach to flood, maximum capacity or pressure drop. The rating mode allows you calculate the pressure drop and approach to flood for existing columns. S.I., Metric and English units are supported and the program can convert between these systems of units. The Eckert and Robbins correlations are both included to cover the full range of liquid flowrates. Calculated results can be printed in tabular form, and plotted as a Generalized Pressure Drop Correlation diagram or as an Operating Diagram. The program includes an extensive illustrated database of packing types from the major suppliers, but custom data can be used as well. The packings included are :-
- Raschig Ring
- Pall Ring
- Berl Saddle
- Cascade Mini-ring ( trademark of Koch (Cyprus) limited )
- Flexiring ( trademark of Koch-Glitsch, LP )
- Hy-Pak ( trademark of Koch-Glitsch, LP )
- Intalox ( trademark of Koch-Glitsch, LP )
- Snowflake ( trademark of Koch-Glitsch, LP )
- Jaeger Tri-Packs ( trademark of Jaeger Products, Inc. )
- Nutter Ring ( trademark of Nutter Engineering )
- Super Torus Saddle ( trademark of Raschig AG )
- Ralu Ring ( trademark of Raschig AG )
A detailed illustrated manual and tutorial are included in Adobe Acrobat (i.e. PDF) format. The cost of the program is US $80-00 for a single user license and US $250-00 for a multi-user site license. The following screen shots illustrate PackCol in action :
The Packed Column Calculator's Main Screen
The options for the calculation are set in the boxes across the top of the window. The packing details can be either entered on the left side, or selected from the built in database. The gas and liquid details are keyed in on the right and then the calculation can be performed. This form shows the basic results, and a more detailed set of results can be obtained by clicking the "Detail Calc" button. The Packed Column Calculator's Packing Database
An extensive database of standard packings is built into the Packed Column Calculator program. Custom packing factors and data can be keyed in, and saved as a calculation template for future re-use. The Generalized Pressure Drop Correlation Diagram
Plotting the Generalized Pressure Drop Diagram allows the PackCol results to be easily compared with hand calculation results, and to get a "feel" for how stable the column is likely to be. The Operating Diagram
Although the Operating Diagram is discussed in every handbook on column design, it is simply too much work to produce by hand and was rarely used in the past. However, PackCol generates the Operating Diagram instantly - giving the engineer an extremely powerful tool to investigate the effect of changes in liquid and gas flow.
