An innovative self-heat recuperation technology has been developed for heating and cooling thermal processes, in which not only latent heat but also sensible heat are circulated in a feed−effluent heat exchanger of the thermal process by compressing the effluent stream without any heat addition. Applying this technology to the thermal processes, the amount of energy required was determined using a commercial process simulation tool, PROII. The proposed self-heat recuperation technology, in which

In this paper, an integrated energy-saving process module based on self-heat recuperation for distillation processes is proposed; the energy saving in this module occurs via heat circulation. The proposed integrated process module consists of a heat circulation module and a distillation module in which the heating and cooling loads are balanced by exergy analysis. The self-heat recuperation technology proposed in our previous studies is adopted, and thus, the heat of condensation and the cooling

In this paper, an exergy analysis and a calculation method for a self-heat recuperative thermal process are described. Self-heat recuperation technology has recently been developed and has the characteristics whereby total process heat can be recirculated within the process, leading to a marked reduction in energy consumption. Although this technology can achieve perfect heat circulation in the process, the minimum energy required for the thermal process has not previously been described. Accord

In this paper, an innovative design methodology is proposed for production by azeotropic distillation using self-heat recuperation technology to reduce energy consumption. Based on this design methodology, the heat of the distillate and condenser in each distillation column is recovered by compressors and exchanged with the heat of the corresponding feed and reboiler. Hence, a larger amount of heat, which consists of the sensible heat and latent heat of the process streams, is circulated within

Abstract In this article, a novel design methodology based on self‐heat recuperation for a heat integrated distillation column (HIDiC) is proposed. HIDiC is a well‐known energy saving distillation process, in which the condensation heat of the rectification section is recovered and exchanged with the vaporization heat of the stripping section. By following self‐heat recuperation technology, the energy input/output of the HIDiC can be analyzed and the whole process heat can be recirculated by pre
