Mar 25, 2021 HRPG raises energy efficiency and reduces dust emissions impact. ... compared efficiency of steam cycle and ORC for HRPG of cement plants, and their study showed that the former had higher efficiency than the latter when exhaust gas temperature exceeded 310 C. So the HRPG system in the case study has good representativeness in the country. While China produced 56 % of the worlds cement in 2018, its emissions were 52 % of the total, a consequence of its clinker ratio being less than 0.60 in recent years, below the world average. The rebound in Chinas cement production and a higher clinker ratio in that country (Fig. C3) are the main reasons for global emissions to have regained ...

The Aganang and Delmas plants were designed to have limited environmental impact, and SepCem further reduces its impacts with mitigatory measures for any dust and/or noise pollution. Limestone is the principal raw material for cement, and it is used to manufacture clinker at SepCems technologically advanced plants. Additionally, it reduced the freshwater demand in its cement plants through the use of harvested rainwater in plants and recycled water use. As a result, Dalmia Cement became 12.4 times water positive in FY 2020-21 at a group level.

environmental and social impacts of cement industries

emissions from a dry kiln with preheater and precalciner is typically 1.5 kg/t of clinker compared to 4.5 kg/t for the wet process. The NOx emissions can be reduced further to 0.5 kg/t of clinker by after burning in a reducing atmosphere and energy of the gases recovered in a preheater/precalciner. For control of fugitive particulate emissions, Carbon dioxide captured from the emissions of a cement processing plant can be sequestered in concrete forever. Once injected, the CO2 reacts with the calcium ions in cement to form nano-sized calcium carbonate minerals that become permanently trapped in the concrete. This is an alternative to the common practice of transporting liquid
