Cement production is one of the most energy intensive industrial processes, accounting for ∼5% of the total CO2 anthropogenic emissions, with 2/3 of these emissions attributed to limestone calcination. In the course of the SOLCEMENT project a novel process has been developed, where concentrated solar energy is used for limestone calcination instead of fossil fuels, while a thermochemical energy storage reactor able to transfer energy from daytime to the night operation is also implemented. The preliminary process described in previous work, assumed that CO2 from calcination is mixed with the flue gases, while the updated version of the process presented here, facilitates co-integration with CO2 capture schemes by utilizing separate streams for a) the high-quality CO2 produced from calcination and b) the flue gases of the calciner burner during night operation. This updated process is modeled by Aspen PlusTM V11 and compared with the conventional one in terms of both CO2 emissions and energy consumption. It is shown that a reduction of 32% in fossil fuel energy consumption and 8.6% in CO2 emissions per kg of clinker is possible. [ABSTRACT FROM AUTHOR] |
