Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.The package contains models for performing distillation and packed column calculations.For distillation there is a basic model performing just the material and energy balances, without any treatment of the necessary number of contact stages. A binary distillation model, and a more complex multicomponent model.
For packed columns, the Sherwood-Lobo model will perform simple hydraulic calculations. In order to obtain the height of the transfer unit more complex models are needed. For unstructured packing there is the Onda model, and also the very complete Billet-Schultes model. For the last one, the packing characteristics to use can be found at "Prediction of mass transfer columns with dumped and arranged packaging", Trans IChemE, Vol.77 Part A, September 1999. For structured packing there is the Delft model.
