Abstract
A system includes a gas turbine system and an aftertreatment system coupled to an exhaust outlet of the gas turbine system and configured to treat exhaust gases exiting the exhaust outlet. The aftertreatment system includes a cooling unit configured to cool the exhaust gases and a carbon dioxide (CO2) treatment unit coupled to the cooling unit and configured to treat cooled exhaust gases by reducing an amount of CO2 in the cooled exhaust gases with lithium hydroxide (LiOH). The aftertreatment system includes a LiOH supply unit coupled to the CO2 treatment unit and configured to feed LiOH into the CO2 treatment unit such that a reaction between LiOH and CO2 occurs inside the CO2 treatment unit to convert CO2 into lithium carbonate (Li2CO3) and water (H2O). The aftertreatment system also includes a treated exhaust outlet coupled to the CO2 treatment unit and configured to discharge treated exhaust gases.
