Carbon dioxide and heat integration of industrial parks

The depletion of natural resources and the increase in greenhouse gases emissions has led to policies aiming at drastic carbon dioxide emissions reductions over current levels. This work addresses the carbon dioxide integration of industrial parks, i.e. the integration of carbon dioxide sources, sequestration and utilization options to achieve required emissions reductions at minimum cost. The work makes use of the recently proposed carbon dioxide integration approach to explore carbon management options across an industrial park together with energy integration approaches to (1) minimize net energy demand of the industrial park and therefore cut fuel and corresponding emissions, and (2) explore synergies available from utilizing excess process heat to provide low-cost, emissions free heat and power sources for energy intensive carbon capture and compression costs. The proposed approach integrates methods for carbon dioxide and heat integration. The approach is demonstrated through a case study for which substantial savings are identified with the new approach.
