Additionally, burning fossil fuels to achieve the required calcination temperature of 1,450 degrees results in further CO2 emissions. Because of that, CO2 emissions linked to the cement industry ...
The cement industry is one of the largest producers of carbon dioxide. It is responsible for up to eight percent of global man-made emissions – almost three times as much as the global air traffic. To ...
The Yarwun Hydrogen Calcination Pilot will demonstrate the viability of using hydrogen in the calcination process, where hydrated alumina is heated to temperatures of up to 1,000 degrees Celsius.
These two processes are unusual because the majority of their emissions come not from fuel combustion but from the calcination of limestone (CaCO 3), producing lime (CaO) and CO 2. Calcination is ...
