Interplant Carbon Integration Towards Phased Footprint Reduction Target

This work presents a first attempt to define and address the multi-period carbon dioxide network synthesis problem for industrial parks. The problem is to determine over time an optimal carbon dioxide reuse networks for reducing the net emissions of the industrial park by utilizing carbon dioxide source flows in carbon dioxide sinks. The formulated optimisation model determines the optimum amount of CO₂ that is to be captured in different time periods with an objective of minimizing total cost of treatment and equipment. It takes into account information on carbon dioxide sources, existing and options for additional sinks, capture and transmission, expansion plans for the industrial park and carbon reduction targets. The approach is illustrated with an example.
