AB  - The present work examines the start-up process of the membrane-based oxyfuel process proposed in the OXYCOAL-AC project (project duration 2004 to 2011). The focus of the work is on a model-based control approach investigated as part of the project participation from 2007 to 2010, which can be used to carry out the start-up process of this process, which requires a large number of additional steps compared to the start-up process of conventional coal-fired power plants due to the novel process structure of the flue gas recirculation and its enrichment with oxygen in a membrane system. While the original research focused on the use of oxyfuel combustion in coal-fired power plants, the focus today is increasingly on industrial processes such as the cement industry or waste incineration, where CO2 emissions are generated by material conversions in the process. Building on the findings of the OXYCOAL-AC project, general follow-up activities in the field of oxyfuel combustion (SFB Oxyflame) and oxygen supply using membranes (MEM-OXYCOAL and HETMOC) have taken place. The basis for the analysis of the start-up process of the OXYCOAL-AC process is the extension and modification of a component library so that a detailed non-linear model of the entire process can be created, with which the entire start-up process from power plant shutdown to load increase to 100
