  1. Integrated Process Design • RESIDUE MAPS

  2. i-PrOH (82.3ºC) AZEOTROPE (80.4ºC) WATER (100ºC) ACETONE (56.3ºC) • Residue Maps • Residue Curves definition “Experimentally, residue curves can be obtained as the composition of the liquid remaining in a still when vapor is continuously boiled off in an open simple distillation process.” Wahnschafft O.M. Et al., Ind. Eng. Chem. Res. 31 (10), 1992.

  3. i-PrOH (82.3ºC) AZEOTROPE (80.4ºC) WATER (100ºC) ACETONE (56.3ºC)

  4. i-PrOH (82.3ºC) AZEOTROPE (80.4ºC) WATER (100ºC) ACETONE (56.3ºC) SEPARATION regionS A mixture located at region 1 can not be splitted in streams located at region 2. Region 1 Region 2

  5. Residue Maps (Douglas, J.M., “Conceptual Design of Chemical Processes”, Chemical Engineering Series, McGraw-HillNew York (1988)

  6. Residue Maps • Using the Residue Map Statement: Predict the distillate and bottoms compositionin a high separation capacity tower for a specified distillate flow. D = 1 xiD = ? ? Acetone 1 i-PrOH 8 Water 1 xiW = ?
