Techno-Economic Analysis and Optimization of Hybrid Absorption Processes for CO2 Capture from Lime and Cement Plants

Technisch-wirtschaftliche Bewertung und Optimierung hybrider Absorptionsverfahren zur CO2-Abscheidung aus Kalk- und Zementwerken

Masterthesis, Bachelorthesis

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.

Dyckerhoff cement plant Göllheim: the raw meal from this plant is investigated for its usability in the indirectly heated carbonate looping process.
