Abstract

The carbon dioxide concentration in the atmosphere has increased strongly over the few past decades as a result of the dependency on fossil fuels for energy production. The global atmospheric concentration of CO2 increased from a pre-industrial value of about 280 ppm to 390 ppm in 2010 [4]. Thus, various effects are taken into consideration in order preserve the well being of the planet Earth for future generations. One of the main studies hovering over this issue is the implantation of Chemical Looping Combustion (CLC). Due to the low efficiency of the CLC mechanism, this technology has not yet been considered as a grand scale model. However, considering the effectiveness of this system on lowering the carbon dioxide concentration in the atmosphere and improving effects on human life, it is promising that CLC mechanism can soon become one of the main important power generation systems. Through this study, the overall efficiency of the system and its effectiveness is studied. Through a detailed modeling of basic/un-pressurized CLC system, the main components and their effectiveness such as percent of heat recovery, amount of operation energy, and overall net power created was first analyzed. By knowing the outcomes of the unpressurized system, the main objective of this research was set to improve the overall efficiency by considering different scenarios and instances. In order to do so, three main programs were utilized. In order to perform the thermodynamic analysis of the overall system, MatLAB was used. Some of the crucial informations that were found through the usage of MatLAB include: temperature crossing, maximum allowable operating temperature, and efficiency of the system considering different hypothetical conditions.
