Global cement emissions standards

Global cement emissions standards

Feb 21, 2014 In the face of increasing limits on mercury emissions, cement plants can take two approaches to reduce their mercury emissions. Firstly, careful selection of input materials, specifically limestone and fuels, can reduce the quantities entering the system. Secondly mercury vapour and compounds can be absorbed onto carbon dust in the stack.

CEMS Challenges for Cement NESHAP

CEMS Challenges for Cement NESHAP

The EPA limit for mercury emissions is in units of pounds of mercury per million tons for cement clinker production, on a 30-day rolling average. So the DAS must get a signal from the plant data system for clinker production and incorporate that into the calculations. That could be from a weigh feeder that actually handles clinker or the kiln feed.

Mercury species mass flows and processes in a cement

Aug 01, 2010 Cement clinker is formed in the temperature range of 1000–1450 C and is then released from the kiln through the satellite clinker cooler. 10% of the air enters the kiln directly through the burner, while the main stream of combustion air enters the kiln through the clinker cooler and is thus preheated by the hot clinker.

Mercury emissions are typically higher in kiln operations with the raw mill-off (“direct” operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging (bleeding) of cement kiln dust from the system is an efficient way to control and reduce mercury emissions.
