The most difficult and time consuming aspect of the design of packed columns is the hydraulic part. If the designer wants to try many different conditions, many repetitive calculations will have to be performed. Also, some inaccuracy is incurred when trying to use the U.S. Stoneware curves. The graphs are hard to read and almost impossible to interpolate between the parametric lines. The purpose of the program is to give a more accurate calculation by using equations for the pressure drop lines, interpolating between them and correcting for gas density for each foot of packing. The program also allows changes in gas and liquid flow rates, gas density, packing type and size bed height and column diameter which makes for easy comparison. between many proposed columns.

Given the gas and liquid flow rates, gas and liquid densities, liquid viscosity, column pressure and temperature, type of packing, and whether the system is foaming or nonfoaming, the program will will develop the optimum column design based on the characteristics and restrictions of the program. The program will specify packing size, the maximum allowable bed height, total and incremental pressure drop through the packing, superficial vapor velocity and percent of flooding. For each foot of packed height it will also interpolate between the pressure drop lines and correct for the effect of pressure on the gas density.
