Empower your process with digitalisation. Across your cement flowsheet, your equipment offers a wealth of information about how efficiently your process is performing. Capturing this data in real time is key to achieving optimum performance – as well as increasing the availability factor. That's where digital tools come into their own.

Technologies designed to capture and store CO2 emissions from industrial operations are rapidly gaining traction, but finding ways to economically utilize the captured CO 2 has posed challenges. A team of A team of engineers from the University of California Los Angeles' Institute for Carbon Management have developed a new cement formulation, into …

Cement, a key ingredient in concrete, accounts for about 7% of global CO2 emissions and is the second-largest industrial emitter of CO2 after the iron and steel industry . The cement production process is responsible for 95% of concrete's carbon footprint.

In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

Moreover, while the cement industry has seen major advancements in IT infrastructure and operational technology over the past two decades, return has been below expectations. The efficacy of new enterprise-resource-planning systems, process-optimization tools, and even predictive maintenance has lagged behind due to change-management …

Unlike most industrial processes, process chemistry rather than fuel combustion is responsible for almost two-thirds (64%) of the CO 2 emissions emanating from the Portland cement industry. (1) As shown in Figure 1, around 880 kg CO 2 is generated per tonne of clinker in a typical (1 Mtpa, 3 000 tpd) cement plant, (2) which produces CEM I (95% clinker).

Accurate cement production also depends on belt scale systems to monitor output and inventory or regulate product loadout, as well as tramp metal detectors to protect equipment and keep the operation running smoothly. The …
