15 de ene. de 2024 · This study evaluates various technical options for achieving deep decarbonisation in a clinker production facility by utilising hydrogen (H 2) as an alternative fuel to replace fossil fuels and by integrating an oxy-combustion technique with carbon capture and storage (CCS).
Process heat overview. Clinker, and clinker substitutes, are the active components that confer cement its binding properties. Producing traditional cement clinker is an extremely energy and CO2 intensive process. In the EU, 90% of clinker is now made via the more energy efficient dry clinker-making process (2).
1 de oct. de 2022 · In this study, the clinker production process is integrated with the dehydrogenation process of NH 3 that produces H 2, which generates the thermal energy required in the clinker production process. H 2 produced from NH 2 decomposition is employed as an alternative fuel for clinker production to reduce the CO 2 emission significantly.
Clinker is produced by heating crushed limestone and a mix of other materials (clay and sand) to 1450 °C in a rotary kiln. Clinker is later ground down to a fine powder and mixed with gypsum and other ingredients to make cement.
16 de jun. de 2021 · Figure 1 A shows the current process for production of cement, which includes three main stages: raw material extraction and preparation, clinker production, and cement grinding. Limestone (CaCO 3 ) is the main feed constituent.
5 de feb. de 2024 · Figure 8 shows a high-level process scheme and the relevant material flows and electricity requirements for the I-CCU pathway, which integrates the production of hydrogen, clinker, and methanol. This pathway utilizes pure oxygen, obtained from the electrolysis of water, as the oxidizing agent for the combustion in the clinker production as in ...
This article is a continuation of the previous article on the indirect mechanosynthesis clinkerization process, which combines mechanical activation (high-energy milling) and thermal treatment at lower temperatures (from 900 °C) than those used for conventional clinkerization to produce clinker.
