Abstract

This study investigates a modification to the cumene hydroperoxide (CHP) production process by removing the cooler between the reactor and separator, aiming to improve energy efficiency. The simulation results show that the modified process requires 245,259,223.09 kJ/h, compared to 265,992,099.05 kJ/h for the basic process, representing a significant energy reduction of 20,732,875.95 kJ/h. The removal of the cooler also leads to lower capital and operating costs, with annual savings of $111,900 in operating costs and $103,580 in utilities. This modification enhances the overall energy efficiency and cost-effectiveness of the CHP production process while maintaining product selectivity and operational performance.

Abstract

Acetone production via isopropyl alcohol (IPA) dehydrogenation is an energy‑intensive process due to the endothermic nature of the reaction. This study aims to minimize net energy consumption by simulating a modified process design that incorporates a Feed‑Effluent Heat Exchanger (FEHE) strategy. The simulation results demonstrate that the modified configuration successfully recovers heat from the reactor effluent to preheat the feed stream to 178 °C, thereby reducing the total energy consumption from 4,695.8 kW to 4,532.0 kW. This energy saving of 163.8 kW confirms that the proposed heat integration is technically feasible and significantly enhances the thermodynamic efficiency of the acetone production process.
