PACKED SCRUBBER DESIGN


Note: yellow cells indicate data to be entered by user

Hydraulic design:
1 Enter liquid and gas flow and properties
2 Enter packing data (copy from 'Packing data' sheet, if appropriate)
3 Enter diameter or % flood, but not both (if both entered, diameter controls).
4 If col diameter is specified, results are immediate
5 If % flood is specified, use 'Tools' 'Solver' to determine colum diameter
6 Messages will warn if scrubber is out of range of the correlation, or if the wetting rate is too low.
7 Packing data is on a separate sheet, and may be copied directly to the hydraulic sheet.
New packing data can be added as desired.
8 The pressure drop sheet is a lookup table used by the hydraulic calculation.  Do not change this sheet.



Mass transfer
1 This sheet corrects experimental values of HTU to different sytems or different flow rates.
2 If both gas and liquid films control, it also calculates overall HTU based on either liquid or gas.
3 If you know the process is controlled by one phase only that HTU need be calculated.
4 The only calculation that uses both Hg and Hl is the H-overall.
5 Enter data for the reference system (for which the known HTU was found) in the first col.
6 Enter data for the desired system in the second column.
7 Enter flow data
8 Diffusion coefficients, if not known, can be estimated using the 'Diffusion coefficients' sheet.
Caution: if you copy the answer, make sure you copy the value, not the formula.
