“…CO 2 capture efficiencies up to 98% were attained. Testing involved the evaluation of different operation conditions, such as high CO 2 concentration (up to 33 vol %; wet basis), high limestone make-up ratios, looping ratios up to 20 mol CaO/mol CO 2 , and carbonator temperatures between 600 and 710 • C. Tail-end CaL was demonstrated under industrially relevant conditions, and is considered to be ready for the demonstration at larger scale in the cement industry [73].…”

CO2 Capture, Use, and Storage in the Cement Industry: State of the Art and Expectations

The implementation of carbon capture, use, and storage in the cement industry is a necessity, not an option, if the climate targets are to be met. Although no capture technology has reached commercial scale demonstration in the cement sector yet, much progress has been made in the last decade. This work intends to provide a general overview of the CO2 capture technologies that have been evaluated so far in the cement industry at the pilot scale, and also about the current plans for future commercial demonstration.

“…Compared with developed countries, emerging economies have limited access to capital and lack the knowledge, public acceptance and government support to reduce emissions (WBCSD-IEA, 2009;Iizuka, 2015). Their advanced counterparts have pioneered solutions in the cement industry by adopting the latest aids, such as stateof-the-art kiln technology and CCS (Jordal et al, 2017;Nabernegg et al, 2017). These approaches complement the use of alternative fuels (AFs) (e.g., tires and industrial waste) (WBCSD-IEA, 2009; Bakhtyar et al, 2017).…”

Cement manufacturing is an energy-and carbon-intensive process and a prominent contributor to global anthropogenic greenhouse gases (GHGs). Within emerging economies, this industry's considerable potential to pollute can be exacerbated by outmoded plant or practices, and management's limited capacity to remediate. In this context, the current study analyses the case of Indonesia's leading producer, recording variations in greenhouse gas (GHG) sources to pinpoint opportunities for reduction. Emissions, measured 20% higher than the 2030 global industry target, occur from the calcination process, abetted by fuel combustion. Reductions should be focused on reducing the clinker-to-cement ratio and promoting the uptake of alternative fuels. Avenues lie in increasing the use of clinker substitutes such as fly ash and limestone, and employing fuels derived from waste and biomass. Both sources are abundant in Indonesia. Further declines in GHGs could be achieved through technological innovations such as the upgrading of kilns. The inquiry provides recommendations for emission mitigation in the cement industry not only in Indonesia but also in other developing countries.

“…This work has been carried out as a part of the Horizon 2020 project "CO 2 capture from cement production" (CEMCAP) [13], which has the overall objective to prepare the ground for large-scale implementation of CO 2 capture in the European cement industry. An essential element in responding to this objective has been to perform a comprehensive techno-economic comparative assessment of CO 2 capture, which can be used as a decision basis for future evaluations of CO 2 capture implementation at Energies 2019, 12, 559 3 of 33 cement plants.…”

A technical evaluation of CO2 capture technologies when retrofitted to a cement plant is performed. The investigated technologies are the oxyfuel process, the chilled ammonia process, membrane-assisted CO2 liquefaction, and the calcium looping process with tail-end and integrated configurations. For comparison, absorption with monoethanolamine (MEA) is used as reference technology. The focus of the evaluation is on emission abatement, energy performance, and retrofitability. All the investigated technologies perform better than the reference both in terms of emission abatement and energy consumption. The equivalent CO2 avoided are 73–90%, while it is 64% for MEA, considering the average EU-28 electricity mix. The specific primary energy consumption for CO2 avoided is 1.63–4.07 MJ/kg CO2, compared to 7.08 MJ/kg CO2 for MEA. The calcium looping technologies have the highest emission abatement potential, while the oxyfuel process has the best energy performance. When it comes to retrofitability, the post-combustion technologies show significant advantages compared to the oxyfuel and to the integrated calcium looping technologies. Furthermore, the performance of the individual technologies shows strong dependencies on site-specific and plant-specific factors. Therefore, rather than identifying one single best technology, it is emphasized that CO2 capture in the cement industry should be performed with a portfolio of capture technologies, where the preferred choice for each specific plant depends on local factors.
