Studies on the conceptual design of energy recovery and utility systems for electrified chemical processes

초록

Industrial energy systems under electrified heating were examined to understand the techno-economic impact of electrification on the supply of heat at the process level and the management of heat and power at the site level. Two case studies for chemical production were conducted to discuss the possible designs of electrified heat supply for processing industries and to compare the characteristics of heat recovery networks and utility systems under electrification with those under conventional fossil-fuel energy systems. The application of the heat-integrated design method is effective in providing design strategies for the transformation to electrified energy systems, as well as in evaluating plant-wide implications of electrification in practice. The design interaction between heat recovery and electrification was also investigated, and the cost-effectiveness of electrified energy systems was found to be highly influenced by heat recovery. The current study demonstrated that industrial electrification can be a practical alternative for industrial energy supply and that electrified heating can be economical with a low-cost and renewable source of electricity.
