At the Institute for Energy Systems and Technology (EST), a promising CO2 capture process, the Indirectly Heated Carbonate Looping (IHCaL), is being developed for integration into lime and cement plants, to reduce the associated CO2 emissions. In order to deploy this technology, the efficient heat recovery of the high temperature flue gases by combustion air preheating is required.

Within the DELTA Project, applied solutions to contribute to the energy transition in Darmstadt are being developed. To reduce greenhouse gas emissions, CO2 can be captured from the Waste-to-Energy plant Darmstadt, and utilized to produce chemicals such as methanol. To achieve this, an efficient tailored process to capture and utilize CO2 (CCU) is required.

The aim of the thesis is to select, design, optimize and asses different concepts for utilizing the CO2 captured from the Waste-to-Energy plant Darmstadt. For this, techno-economic models in MATLAB/excel will be developed, and process modelling (e.g. with Aspen Plus) will be carried out. The results will serve as a basis for the design of a suitable CCU facility in Darmstadt.

At the Institute for Energy Systems and Technology (EST), a promising CO2 capture process, the Indirectly Heated Carbonate Looping (IHCaL), is being developed for integration into lime and cement plants, to reduce the associated CO2 emissions. Combining IHCaL with other capture methods, such as absorption with monoethanolamine (MEA), could further reduce the specific energy consumption (SPECCA) and the cost of the entire system. Some hybrid solutions have been proposed, but a process optimization considering techno-economics is still required to assess the potential.
