Abstract

This study investigates the effect of reactor type, reactor configuration, reactor temperature, and reactant ratio on the formation of propylene glycol from propylene oxide and water using HYSY Simulation Software. The reactor types studied were Continuous Stirred Tank Reactors (CSTR) and Plug Flow Reactors (PFR). The effect of the reactant ratio was investigated by varying the mole ratio of propylene oxide to water. The effect of temperature was studied by varying the reaction temperature from 24 to 40°C. The HYSYS simulation results showed that the PFR resulted in the highest conversion compared to the CSTR. The CSTR configuration in series resulted in the highest conversion compared to the CSTR configuration in parallel. The conversion of propylene oxide to propylene glycol increased with increasing temperature. The reactant ratio of 1:1 (propylene oxide to water) resulted in the highest conversion compared to other reactant ratios. The implication of this study is to provide information on a more efficient and economical propylene glycol process.
