摘　　要：随着双碳政策的进一步向前推进,传统石油化工行业的发展面临着前所未有的挑战。如何在降低碳排放的同时实现能量的最大化利用备受关注。精馏是化工生产过程中最常用也是较为高效的分离手段。但是精馏过程往往伴随较大的能量损失。选择节能的精馏工艺,优化换热网络,促进能量集成,并同时采用高效的精馏设备,不仅能够提高精馏效率,降低有效能损失,节约生产成本,为企业来带可观的经济效益;而且推动了节能降碳目标的实现,提高了化工企业在碳交易市场上的竞争力。结合理论背景,对精馏过程的节能技术展开介绍并对其发展方向作出展望。Traditional petrochemical industry has been faced with tremendous challenges due to the boost of “Carbon Peaking and Carbon Neutrality” policy.Therefore, it has aroused great concern to maximize the energy utilization with a lower carbon emission. Distillation is an efficient separation method in chemical industry, which has been used overwhelmingly. However, distillation is also one of the most energy-consuming processes. Exergy loss and operating costs will be reduced by adopting energy-saving distillation process and optimizing heat-exchanging networks, which will bring economic benefit and realize energy integration.Combined with high-capacity distillation equipment, separating efficiency will be largely increased at the same time. Furthermore, employing these methods above,the chemical companies can make progress in cutting carbon emissions and become more competitive in carbon trading market. Based on theoretical analysis,energy-saving strategies were introduced and the future development of distillation were forecasted.
