“… Thermodynamically stable product  High availability of wastes  Reuse product in a variety of application  Decreased leaching of heavy metal trace elements from the wastes  Low CO 2 adsorption capacity  Slow adsorption kinetics and mass transfer  High energy consumption in crushing Bobicki et al, 2012;Chang et al, 2012 CO 2 as carbonate precipitation, which is environmentally benign. The basic goal of accelerated carbonation is to mimic the natural weathering processes in which CO 2 reacts with metal oxide bearing materials to form stable and insoluble carbonates, with calcium-or magnesium-oxide being the most favourable metal oxide in reacting with CO 2 .…”

CO 2 capture, utilization, and storage (CCUS) is a promising technology wherein CO 2 is captured and stored in solid form for further utilization instead of being released into the atmosphere in high concentrations. Under this framework, a new process called accelerated carbonation has been widely researched and developed. In this process, alkaline materials are reacted with high-purity CO 2 in the presence of moisture to accelerate the reaction to a timescale of a few minutes or hours. The feedstock for accelerated carbonation includes natural silicate-minerals (e.g., wollastonite, serpentine, and olivine) and industrial residues (e.g., steelmaking slag, municipal solid waste incinerator (MSWI) ash, and air pollution control (APC) residues). This research article focuses on carbonation technologies that use industrial alkaline wastes, such as steelmaking slags and metalworking wastewater. The carbonation of alkaline solid waste has been shown to be an effective way to capture CO 2 and to eliminate the contents of Ca(OH) 2 in solid residues, thus improving the durability of concrete blended with the carbonated residues. However, the operating conditions must be further studied for both the economic viability of the technology and the optimal conditions for CO 2 reaction.

“…According to the observations reported in the literature (Bobicki et al, 2012;Chang et al, 2012a;Pan et al, 2014), the key operating factors affecting the carbonation reaction include reaction time, liquid-to-solid (L/S) ratio, temperature, pressure, and initial pH of solution. As a result, carbonation processes should be critically assessed under different operating conditions.…”

“…of industrial alkaline solid wastes including steelmaking slag, cement kiln dust, waste ash, paper mill waste and mining waste are recommended for mineral sequestration (Costa et al, 2007;Li et al, 2007;Pérez-López et al, 2008;Huntzinger et al, 2009;Bobicki et al, 2012;Pan et al, 2013a). Steelmaking industries, one of the largest sectors generating abundant CO 2 , accounting for 6-7% worldwide, produce significant quantities of waste slag with high mass fractions of calcium, exhibiting a potential for carbonation.…”

“…On the other hand, indirect carbonation is accomplished by extraction or bioleaching prior to carbonation. The challenge of mineral sequestration is to accelerate the carbonation process; while, at the same time, exploiting the heat of reaction with minimal energy and material losses (Bobicki et al, 2012). Recently, scientists have attempted to turn this process into a practical technology and capture CO 2 with lower energy and chemical usage (Eloneva et al, 2008;Baciocchi et al, 2009;Chang et al, 2011b;Eloneva et al, 2012).…”

“…It is postulated that the current warming of the global climate is the result of an increase in anthropogenic greenhouse gas (GHG) emissions, particularly CO2, since pre-industrial times (Canadell et al, 2007). Global average atmospheric CO2 has increased from 280 ppm in the 1750 s to 389 ppm in 2010 (Bobicki et al, 2012). Therefore, efforts to reduce the emission of CO2 are relevant in the current context.…”

In this paper, a static model of cement rotary kilns is proposed. The system model is obtained through polynomial series. The proposed model is contrasted with data of a real plant, where optimal results are obtained. Expected results are measured with respect to the clinker production and the combustible consumption is measured in relation with the consumption calorific. The expected result of the approach is the increase of the profitability of the factory through the decrease of the consumption of the combustible. KeywordsCement rotatory kiln; static model; MISO systems. ResumenEn este trabajo, se presenta un modelo estático de un horno rotatorio de cemento. El modelo del sistema se obtiene a través de series de polinomio. El modelo propuesto se verifica con datos reales de la planta, donde se obtuvieron resultados óptimos. Los resultados esperados son medidos con respecto a la producción de Clinker. El consumo de combustible se mide en relación con el consumo calorífico. Los resultados esperados del enfoque es el incremento de los beneficios de la empresa a través de la reducción en el consumo de combustible.
