A comprehensive step-by-step Aspen Plus simulation for limonene epoxidation in a batch reactor using a Langmuir – Hinshelwood – Hougen – Watson (LHHW) kinetic expression is detailed described. Model validation is presented by comparison of the Aspen Plus simulated data and laboratory-scale experimental data. The RMSD between experimental and simulated data lies around 4x10-4. Thus the presented model is a valid tool for studying and analyzing the conceptual design and scale-up for the reaction system. This work is currently used in normal sessions of a Chemical Reaction Engineering course and can be used as pedagogic tool for improving inductive as well as deductive mental processes in the Chemical Reaction Engineering students
