Abstract

The indirectly heated carbonate looping (IHCaL) process has been successfully demonstrated to be an innovative technology for CO2 capture in fossil-fueled power plants. Besides this, the IHCaL process is a promising technology for decarbonizing the cement and lime industry due to its synergy to the production process of cement and lime. The feasibility of the IHCaL process in industrially relevant conditions of the cement and lime industry has not yet been proven. In this study, experimental results of longterm pilot tests under conditions for cement and lime industries at a 300 kWth test facility are presented. The necessary heat for calcination was successfully generated by fueling lignite or waste derived fuels in the external combustor. The carbonator was fluidized with circulated flue gas from the combustor. The reactor system showed good hydrodynamic behavior and CO2 capture efficiencies of 90 % in the carbonator were achieved.
