Optimization of ethylene oxide production via hydrogen peroxide process route

Abstract. This study investigates ethylene oxide (EO) production using a Titanium-Silicate (TS) catalyst in methanol, addressing the issue of excess hydrogen peroxide (H2O2). The objective of this study includes developing and validating a process model, evaluating key parameters, and proposing optimized conditions. Aspen HYSYS is used for modeling, and response surface (RSM) methods are applied for parameter analysis. The optimal conditions identified are a reactor temperature of 40˚C, pressure of 8.5 bar, and H2O2 concentration of 2.326 wt.%. Results show high alignment between predicted and modeled EO selectivity (0.06%). Future work could explore recycling streams and improve separation systems to enhance product purity and minimize waste.
