Potential Application of Cement Kiln Dust in Carbon Capture
2023年7月4日 · The implementation of carbon capture, utilisation, and storage (CCUS) technology is one measure aimed at limiting these emissions. This study analyses the mineral carbonation process using CO2 and flue gas as the last stage of the CCUS process applied to cement kiln dust.
processes, cement kiln dust can be collected in two ways: (i) part of the dust can be separated and returned to the kiln from the dust collection system (cyclone) close to the kiln, or (ii) the total quantity of dust generated can be recycled or discarded.
Calcium elution from cement kiln dust using chelating agents, …
2020年4月3日 · In this study, indirect carbonation was carried out by using cement kiln dust (CKD), an alkaline industrial by-product, and three chelating agents (citrate, malonate, and adipate salts) as solvents at the room temperature and atmospheric pressure.
Accelerated Carbonation of Cement Kiln Dust and Lime Kiln Dust …
One of the ways to reduce CO 2 emissions from the cement industry is to react the produced CO 2 with alkaline wastes produced during the manufacturing of cement such as cement kiln dust (CKD) and lime kiln dust (LKD). CKD and LKD are fine-grained, unreacted wastes obtained from the calcination of finely ground limestone fed into cement kilns.
