Process Simulation of Chemical Looping Combustion for a Mixture of Biomass and Coal with Various Oxygen Carriers—Part II

Publication Date Oct 12, 2019


Chemical Looping Combustion (CLC) is an emerging technology that has shown great promise for the capture of almost pure CO2 in combustion of fossil fuels in power plants. In this chapter, the CLC process is modeled in ASPEN Plus and then validated using experimental data from the combustion of three types of biomass as fuels, and Hematite (Fe2O3) as an oxygen carrier (OC). The three types of biomass used in the simulation are Pine Sawdust, Almond Shells, and Olive Stones. The effect of the fuel reactor temperature on gas concentrations (namely CO2, CO, H2, and CH4) in the fuel reactor, and the carbon capture efficiency are examined. It is found that all three biomass types have very high carbon capture efficiencies, with Pine Sawdust and Almond Shell reaching nearly 100 % capture efficiency for temperatures equal to or greater than 950 °C, while Olive Stones reaches a capture efficiency of nearly 100 % at temperatures greater than 980 °C. It is also found that fluctuations in CO2 concentrations in the fuel reactor vary across the three biomass types. The effect of using Mn2O3 as the OC in place of Fe2O3 was also investigated. It was found that switching the oxygen carrier to Mn2O3 caused the concentrations of CO and H2 in the fuel reactor to decrease slightly, while the concentration of CO2 increased slightly. Furthermore, changing the OC to Mn2O3 had no effect on the carbon capture efficiency. Additionally, a mixture of coal and biomass at 895 °C was used with each of the two oxygen carriers, and the results were compared. ...
