Description
Summary:In this paper we analyse the economic and technical effects of using CO2 rich natural gas in an industrial park. The basis for our work is a technical-economic description the processes in the different plants. A mathematical model is established that enable analysis and optimisation of design and operation of the industrial park. The model optimises maximizes the net present value of the available investment and operation opportunities. The candidate plants that we consider in our case study are; a DRI plant, a steel plant (EAF), a methanol plant, a carbon black plant, a combined cycle power plant and a carbon capture facility. We use Norway as a case study due to the political ambitions of increasing domestic consumption of natural gas to achieve a higher level of innovation and industrial development. Several scenarios are analysed, and the main findings from this case study are that there could be both environmental and economic benefits by using a CO2 rich gas in an integrated industrial park.
