Simulation of Chemical Processes involving Chemical Reactors in HYSYS Objective : Compare the use of different reactor types to model one reaction. Problem: Create a flow sheet diagram for the production of Ethyl Acetate (C 4 H 8 O 2 ). Ethanol (C 2 H 5 OH) is combined with Acetic Acid (CH 3 COOH) to Ethyl Acetate in a reactor. The reaction is: C 2 H 5 OH + CH 3 COOH C 4 H 8 O 2 + H 2 O Feed: Temperature = 70 o C Pressure = 1atm Water: 8.892 kmol/hr Ethanol: 186.59 kmol/hr Acetic Acid: 192.6 kmol/hr Property Package: NRTL Kinetic Parameters: Reactions are first order with respect to each reactants in the reaction (second order overall).
