The integration of multiple plants through an eco-industrial park (EIP) is an effective pathway for sustainable development. A special class of EIPs is the carbon-hydrogen-oxygen symbiosis network (CHOSYN) in which hydrocarbon species from various plants are transformed into other species to create synergistic opportunities among the participating plants. Recent research contributions in this field have focused on the multiscale mass and energy integration of CHOSYNs for existing resources but without consideration of planned activities that can alter the resources to be integrated within the EIP. In some cases, there are planned expansions of existing plants in the EIP or the addition of new facilities and resources that require careful planning over a certain time horizon. This work introduces a systematic design approach for the design of the CHOSYNs over a planning time horizon while accounting for the variabilities in the sources associated with the participating plants and the market demands. A moving horizon superstructure representation is developed, and the design problem is posed as an optimization problem. Cash flow diagrams are used to evaluate the net present value (NPV) over the planning time horizon. A case study on hydrogen purification that includes five plants is solved to show the merits of designing an EIP over a time horizon.
