Extraction column simulation

feed + solvent -> extract + raffinate (countercurrent LLE)

Simulate it free Browse example flowsheets

Parameters

n_stages [int >=1], distribution_coefficients {solute: K_D = extract/raffinate ratio}, pressure/temperature [optional] — two inlets (feed, solvent) -> extract + raffinate. Countercurrent LLE cascade; recovery rises with stages (Kremser limit at constant K_D)
