Heat integration of alternative Ca-looping configurations for CO2 capture 2016 Access copy available to the general public Unrestricted The best option to overcome the energy penalty in Ca-looping is to take advantage of the surplus heat by external integration to produce additional power and increase net efficiency. As calciner represents the main energy consumption, another possibility is to internally use the surplus heat to preheat the solids entering this reactor. The objective of internal integration is to reduce the energy demand per captured tonne of CO2. It represents a reduction of the coal and oxygen needs and also a total decrease in the CO2 generation regarding the ordinary configuration. However, the amount of available heat for extra power generation by external integration, essential for the viability of this technology, is also reduced. This is the case of the configurations including a cyclonic preheater or a mixing seal valve. This study assess the energy penalty minimization that may be reached by external integration of these internal energy integration configurations. A methodological process has been applied to obtain a reduction of the energy penalty with respect to the ordinary configuration. This energy saving combined with the lower size of equipment and reduced capital cost would make the cyclonic preheater the most suitable configuration to improve the viability of this technology. info:eu-repo/grantAgreement/ES/MINECO/ENE2013-45353-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.52 2016 THERMODYNAMICS 3 / 58 = 0.052 2016 Q1 T1 ENERGY & FUELS 17 / 92 = 0.185 2016 Q1 T1 1.974 2016 Building and Construction 2016 Q1 Civil and Structural Engineering 2016 Q1 Electrical and Electronic Engineering 2016 Q1 Pollution 2016 Q1 Industrial and Manufacturing Engineering 2016 Q1 Mechanical Engineering 2016 Q1 Energy (miscellaneous) 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Martínez, A.
