摘　　要：在当前全球能源危机和环境保护的大背景下,化工行业正面临着提高能效与减少环境污染的双重挑战。在酯化反应精馏生产碳酸二甲酯的过程中高能耗问题不仅增加了生产成本,也加剧了环境压力。针对这一目标,研究采用Aspen Plus流程模拟软件,构建精确的酯交换法反应精馏模型,并集成热泵系统进行模拟分析。研究重点聚焦于热泵系统与传统反应精馏过程的能耗对比分析。研究结果显示,采用热泵技术的反应精馏系统能显著提高能源利用效率,与常规工艺相比,热负荷节能效率达89%。这一发现不仅为碳酸二甲酯的生产提供了一种节能减排的新途径,也为其他化工过程的能效改进提供了参考。In the context of the current global energy crisis and environmental protection,the chemical industry is facing the dual challenges of improving energy efficiency and reducing environmental pollution.In the process of esterification reactive distillation to produce dimethyl carbonate,high energy consumption not only increases the production cost,but also intensifies the environmental pressure.Aiming at this goal,Aspen Plus process simulation software was used to construct an accurate esterification reaction distillation model,and a heat pump system was integrated for simulation analysis.The research focuses on the energy consumption comparison between heat pump system and traditional reactive distillation process.The results show that the esterification reaction distillation system using heat pump technology can significantly improve the energy utilization efficiency,and the heat load energy saving efficiency is 89%compared with the conventional process.This discovery not only provides a new way of energy saving and emission reduction for the production of dimethyl carbonate,but also provides a reference for the improvement of energy efficiency in other chemical processes.
