Abstract
Global Warming caused by the Greenhouse gas has become a serious global issue due to the increasing in the use of fossil fuel and it is being exhausted. Recently, a great deal of research is being carried out to develop alternatives to fossil fuels. The oil sands have become one of the alternative energy sources. However, it is composed of about 10% bitumen and the rest becomes waste. Moreover, oil sands need a large amount of natural gas to provide heat and steam for bitumen extraction. In this study, it has been focused on the satisfaction both CO2 reduction and waste disposal by using spent oil sand after extraction bitumen from oil sand. Additionally, Aspen Plus was used to simulate to know about its carbonation reactivity. First, we analyzed the analysis of spent oil sand and discovered that it is of mostly composed of SiO2, so it needs pretreatment with CaO aqueous solution. After the pretreatment, it is performed by changes in temperature and pressure. The optimum is decided 500°C, 25 atm and reduced rate of mass was calculated 21.92% about carbonation reactivity by using simulation.
