چکیده

Chemical Looping Combustion (CLC) is a low-cost CO2 capture technology highly competitive for industrial and energy applications. Up to date, CLC has been mostly developed at atmospheric pressure. Pressurized may bring additional advantages due the intensification of process. The main objective this work was determine whether an increase in operating pressure could improve fuel conversion systems gaseous fuels when ilmenite used as oxygen carrier. Fluid dynamics considerations were evaluated window suitable design parameters pressurized conditions. A theoretical model previously validated modified consider fluid reaction kinetics conditions, both bubbling turbulent regimes, using natural gas estimated function several parameters, such velocity, particle size reacting temperature. Uncompleted combustion predicted limited improvement discussion about required reactivity carrier achieve complete performed. Furthermore, analysis system or (0.5 MPa) conditions with reactor designed under regimes carried out Aspen HYSYS process simulation software two different applications heat generation: production domestic hot water steam. From balance, it be concluded that efficiency achieved slightly higher than obtained pressure, essentially because possible use latent condensation generated reactor. In addition results work, thorough assessment technical risks techno-economic would order make final decision feasibility systems.

Effect of gas composition in Chemical-Looping Combustion with copper based oxygen carriers: Fate of sulphur

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can

Dynamic Model of Single-reactor Chemical Looping Combustion

The paper presents a simplified model of chemical looping combustion in a fixed bed reactor under isothermal condition. Both reduction and regeneration phases of the oxygen carrier are modeled in the single reactor model under the hypothesis of discontinuous feed and simplified reaction kinetics. This model is meant to be the simplest possible formulation for a description that incorporates all...

Simulation and validation of chemical-looping combustion using ASPEN plus

Laboratory-scale experimental studies have demonstrated that Chemical-Looping Combustion (CLC) is an advanced technology which holds great potential for high-efficiency low-cost carbon capture. The generated syngas in CLC is subsequently oxidized to CO2 and H2O by reaction with an oxygen carrier. In this paper, process-level models of CLC are established in ASPEN Plus code for detailed simulati...
