| Summary: | Carbon dioxide (CO2) emission has been increased utilizing energy from industry process. It is environmentally important to mitigate atmospheric CO2 emissions. To reduce CO2 emissions, the sequestration of CO2 is an alternative method. For this purpose, CO2 mineral carbonation was conducted utilizing olivine mineral (MgSiO4) at various sizes and temperatures. The reaction rate was increased with increasing the temperature and pressure; therefore, CO2 is highly sequestrated. The use of thermal process in three neck flush, optimum temperature of olivine carbonation was observed. To accelerate mineral carbonation process and extract the reactive component, hydrochloric acid (HCl) was used. The size reduction of olivine into 40, 100, and 250 μm was generated utilizing grinder and sieve machines in order to investigate the effect of increasing surface area on carbonation rate. As conclusion, by increasing the temperature of reaction and reducing size of olivine, the carbonation rate of olivine mineral was increased. |
