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 %.

Recently, major improvement on compressed air energy storage technology has been made by using the heat of compression for heating energy or using it to preheat the compressed air in the expansion phase and by demonstrating its ability to produce cooling energy. Thus, the trigenerative compressed air energy storage has been introduced. In this paper, we introduce a configuration of trigenerative compressed air energy storage system giving the preference to the electric energy production. The study then focuses on undertaking an optimization study via a parametric analysis considering the mutual effects of parameters. This analysis is applied to a micro-scale application including the existing technological aspects. The parametric study results applied on the hot temperature of the thermal energy storage indicate the possibility to find an optimal solution as a trade-off between system performances and other parameters reflecting its cost. On the contrary, the selection of the maximal storage pressure cannot be achieved by finding a compromise between energy density and system efficiency. A complete study of other design parameters will be addressed in a future publication.
