Abstract
Lime plants produce non-avoidable CO2. Calcium carbonate looping carbon capture is used to reduce CO2 emissions from lime plants. Indirectly heated calcium carbonate looping eliminates the air separation unit from the capture process. There are two integration methods considered, tail-end and fully integrated. A techno-economic and environmental assessment has been performed. The tail end case has a larger thermal input but produces more lime and electricity compared to the integrated case, which lowers its break-even selling price. The integrated case has lower project costs and direct CO2 emissions. The capture rate is 90% for the tail-end and 91% for the integrated case.
