Abstract
Abstract Cement production process features intrinsically large CO 2 emission due to the decomposition of limestone by calcination reaction and to fuel combustion, necessary for sustaining the endothermic calcination process and the formation of clinker. Conventional approaches to CO 2 emission reduction in cement plants are based on post-combustion capture with chemical solvents, requiring a substantial energy consumption for regeneration, or oxycombustion in the cement kiln, involving a deep redesign of the plant. The aim of this work is investigating the application of Molten Carbonate Fuel Cells in cement plants for CO 2 capture from the plant exhaust gases, using the fuel cells as active CO 2 concentrators of combustion flue gases and eventually obtaining a purified CO 2 stream through a cryogenic process. A novel configuration with MCFCs added along the exhaust line has been assessed by means of process simulations. The results show a remarkable potential in terms of equivalent avoided CO 2 emissions (exceeding 1000 g/kWh), high share of CO 2 avoided (up to about 70%) and low energy penalties.
