The concept of Heat Integrated Distillation column (HIDiC) was introduced by Mah et al [1] to improve the energy efficiency of distillation processes. Firstly, a brief review of the HIDiC configurations and pilot plants is introduced. The objective of this study is to demonstrate the performance of a new packing specific for HIDiC tested in a concentric HIDiC pilot plant to prove the operability and the overall performance. First, the new specific packing and its characterization are presented. The characterization includes the hydrodynamics, the mass transfer and heat transfer performance. For the experiments on HIDiC pilot plant, several tests are performed at steady state of 90 min. One of these experiments is presented with the operating parameters (boiler heat and pressure ratio). The cyclohexane/n-heptane binary mixture is used for these experiments. The simulation results of a classical distillation column are compared to HIDiC column steady state operation. This comparison demonstrates energy savings about 40 %.

Mah 等人 [1] 引入了热集成蒸馏塔 (HIDiC) 的概念，以提高蒸馏过程的能源效率。首先，简要介绍了 HIDiC 配置和中试设备。本研究的目的是展示在同心 HIDiC 试验工厂中测试的 HIDiC 专用新填料的性能，以证明可操作性和整体性能。首先，介绍了新的特定填料及其表征。表征包括流体力学、传质和传热性能。对于 HIDiC 中试设备的实验，在 90 分钟的稳定状态下进行了多次测试。这些实验之一提供了操作参数（锅炉热量和压力比）。环己烷/正庚烷二元混合物用于这些实验。将经典蒸馏塔的模拟结果与 HIDiC 塔稳态操作进行了比较。该比较表明节能约 40%。
