由于蒸馏是一种应用广泛且能源密集型的分离技术，因此降低蒸馏过程的能耗可以显著节省炼油厂和化工过程工业的成本。精馏塔可以与热泵进行热集成，以减少公用事业提供的能量，也可以集成到整个过程中，为整个过程节省能源。然而，以往的研究还没有充分地研究热泵辅助精馏与整个过程的协同效应。本文针对精馏过程、背景过程和热泵系统的同时热集成问题，提出了一种系统的设计方法。这种整体热集成方法可以为整个过程带来相当大的能源节约。拟议的方法还包括系统地确定热泵的能量最佳布置及其与工艺流程的匹配。此外，还考察了精馏过程改进对整体热集成策略的影响。通过算例说明了所提出的设计方法的应用，并验证了其节能效果。在案例研究中，与基本情况相比，冷热公用事业的能耗分别降低了61.5%和20.6%。
Reducing the energy consumption of distillation processes can lead to significant cost savings in refineries and the chemical process industry because distillation is a widely used and energy-intensive separation technology. A distillation column can be heat integrated with heat pumps to reduce the energy supplied by the utility, and it can also be integrated into the overall process to save energy for the overall process. However, previous studies have not adequately investigated the synergistic effect of integrating heat pump assisted distillation into overall processes. In this paper, a systematic design methodology is proposed for the simultaneous heat integration of distillation, its background process and heat pump systems. Such a holistic heat integration approach can lead to considerable energy savings for the overall process. The proposed methodology also includes systematic identification for the energy-optimum placement of the heat pump and its matching with process streams. Furthermore, the impacts of distillation process modifications on the holistic heat integration strategy are examined. A case study is presented to illustrate how the proposed design method is applied and to demonstrate its effectiveness in saving energy. For the case study, the hot and cold utilities are reduced by 61.5% and 20.6% compared to energy consumptions for the base case.
