Stack Emissions

Cement manufacture generates a high level of particulates, including dust, NOx, sulphur dioxide, carbon dioxide and carbon monoxide. Several of these pollutants are subject to regulation, so must be continuously monitored and controlled. This can be challenging, as the high-particulate environment can adversely affect both the measurements and the instrument.

While cement kilns operate under steady conditions, there are likely to be naturally-occurring variations in the raw materials and fuels involved. This can produce discrepancies in the emissions generated, so even if a plant is usually compliant with regulations, it needs to continue to monitor the process.

The continuous monitoring of particulate emissions helps cement plant operators ensure that they meet control regulations, avoiding the prospect of sizeable fines. It can also help improve operational efficiency, which will lead to lower costs.
