Research PaperOn the simultaneous integration of heat and carbon dioxide in industrial parks

•The approach explores synergies across HI and CCUS, and renewable energy in industrial parks.•An optimization model explores various options to reduce GHGs emissions for minimum cost solutions.•A case study is presented to illustrate the application of the proposed approach.

This work addresses the systematic integration of carbon dioxide (CO2) and excess heat from processing facilities in industrial parks to achieve low cost carbon dioxide footprint reductions. The proposed optimization-based approach simultaneously assesses integration options that encompass the CO2 sources and their potential capture, utilization and storage (CCUS) options across sinks as well as heat and power integration in the cluster through a central utility system and grid. The proposed approach incorporates excess heat from industrial plant and renewable energy options in the form of solar and geothermal steam generation. An optimization model is developed and solved to assess the integration options and identify optimal synergies across the CO2 and energy interfaces, which minimize the total annualized cost of the system. A case study is presented to demonstrate the developed approach and illustrate its use in developing efficient solutions for CO2 emissions reduction in industrial parks.
