Efficient Management of Pollution in Portland Cement Industries

Abstract

There are a number of present situations as well as forthcoming challenges that have been identified, including global warming, climate change, environmental pollution, and the depletion of fossil fuel production. Among the many different types of industries, cement plants are among the most notable zones because they are responsible for emitting fifteen percent of the global pollutions into the surroundings. These pollutants have a negative impact on the health of humans, as well as on the flora and fauna. In the meantime, the utilization of cement-based materials in a variety of fields, including civil and construction engineering, medical field, and other areas, is unavoidable as a consequence of the ongoing increase in population and urbanization. The cement industry is among the most carbon dioxide emission-intensive companies and is classified as one of the largest producers of greenhouse gases. One ton of conventional Portland cement releases about 850 kg of carbon dioxide and 150 kg of other air pollutants when first discovered. Additionally, these pollutants are estimated to be 10% of the stationary admissible sources of CO₂ emissions. To reduce CO₂ emissions caused by energy consumption in the cement industry, the cement plants should change into a 2-stage process that, burning materials are pre-heated by exhausted high-temperature air and rRaw materials and clinker products are pre-heated or cooled by the exhausted hydrate process.

Two difficult problems on the development of a 2-stage cement process include on the chain energy (exothermic and endothermic) of the process, the pre-heated effect and temperature should be favourable and the static optimization of pyramid physicochemical reactions should be favorable to guarantee the final product's strict quality. This paper describes the development of a novel method of pollution control for cement industry which minimize pollutants.
