We use COCO as tool for testing ChemSep columns in(petro)chemical process simulations. This free simulation tool is a great platform for students to become familiar withvarious commercial chemical processes and the simulation techniques required for design and optimization of chemicalprocess plants. If you are unfamiliar with COCO there are two introductions you can read to get started quickly:CAPE-OPEN Flowsheet Simulations with ChemSep andFlowsheeting with COCO and ChemSep (2010)

This mixture formsmultiple azeotropes and its triangular diagram has several distillation boundaries at atmospheric pressure. The feasibility of the process wasconfirmed using rigorous steady-state simulations. This 3 column line-up is the most optimal column sequence in a global optimization to separate the azeotropic mixture.[fsd][png]Acetone is produced via several alternative processes, one of which is the Acetone Process via Dehydrogenation of 2-Propanol (IPA).This endothermic gas-phase reaction converts IPA to acetone and hydrogen. The process has two distillation columns and an absorbercolumn in which a water stream is used to recover acetone. In Ind.Eng.Chem.Res. Vol. 50 pp. 1206-1218 (2011)Luyben showed that operating the absorber at an elevated pressure reduced Acetone losses but increases vent losses and raises the required temperature and cost of thevaporizer heat source. It also adversely affects the reaction kinetics because the reaction is non-equimolar and conversion decreases with increasing pressure.As such, a higher reactor temperature is required to achieve the desired conversion.
