While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high temperatures in a kiln in a fuel-intensive process known as pyroprocessing (Exhibit 2).

Our pyroprocessing technologies have been developed over many years. Whether you burn tradition fossil fuels or alternative fuels, they will help you increase your cement plant's efficiency and uptime – delivering maximum value from your pyroprocessing system.
Sep 04, 2013· What is Pyroprocessing in Cement Plant? This is the kiln treatment stage, when the finely ground raw meal is raised up to a temperature at which it is semi-molten. After decomposition of some clay compounds and dearbonation of the calcium carbonate, further temperature increases result in the formation of hydraulically active calcium sillcates ...
Today we are going to start here one very important topic i.e. Pyroprocessing in cement industry. We will understand the various terminologies and engineering concepts used in cement technology with the help of this category. Further we will go for discussion of chemistry of cement, hydration of cement, properties of cement compounds, selection ...
A senior U.S. State Department official last week said the Obama administration views the experimental pyroprocessing technique as a form of nuclear fuel reprocessing, potentially dimming prospects for South Korea to secure the right to use the technology in a new atomic trade pact with the United States, Arms Control Today reported (see GSN, Feb. 28).
