Process Knowledge
Process knowledge underpins everything – but it’s not something that comes easy. It’s taken us since 1856 to become the experts we are today.
Pyroprocessing
The pyroprocess is the central element to the clinker-making process. Without heat – and lots of it – the raw meal would not react to create the cementitious material that is so important to modern life.
But creating the temperatures required to form clinker comes at a cost. Reaching 1500 °C in the kiln, the cement pyroprocess is one of the hottest industrial processes and requires a huge amount of energy, traditionally in the form of fossil fuels (most often coal). Meanwhile, the chemical reactions that take place as the raw meal is turned into clinker release various pollutants – including NOx and significant quantities of CO2 from the breakdown of limestone. The cement pyroprocess therefore presents a range of challenges: from the purely economic (in terms of energy costs) to the social costs of air and ecosystem pollution, and, of course, the environmental. Since building the first preheater, we have been at the forefront of development efforts to tackle all of these challenges. The preheater alone helped to cut heat consumption in the pyroprocess by nearly 50 % at the time.
Subsequent innovations have continued to improve energy efficiency and reduce energy costs, e.g., by allowing greater use of alternative fuels, as well as controlling the production of pollutants, and improving reliability and availability through the pyro line. As we look to the future, we know cement production will never be a truly clean process. We are however committed to using the latest technologies to relentlessly improve the performance of our pyroprocessing equipment and so to reduce the environmental impact of cement production. Because we believe that what is good for the planet can ultimately also be good for our clients’ business. The times are changing; there is no doubt about it. But we are one old dog that can still learn new tricks.
