Partial Capture of Carbon Dioxide from Industrial Sources - A Discussion on Cost Optimization and the CO2 Capture Rate

Paper in proceeding, 2017

This work discusses the cost optimal capture rate of absorption based carbon capture processes by a combination of process simulations and cost-estimation. The influence of the quality of the CO2 source (quantity, continuity and CO2 concentration) and the availability of low cost heat on the absolute and specific capture cost are highlighted. The results stress that partial capture of CO2 could lower the specific capture cost (€/ton CO2) and that the relation between capital expenditure and lowered energy demand should be reconsidered for cases with access to low-cost heat.
