Reducing CO2 in US cements
The US cement market is increasingly accepting lower-carbon cements such as Portland limestone and ternary blended cements. Cement producers such as CalPortland Cement are including these types of cement to help lower their carbon footprint as part of a range of decarbonisation measures. By CalPortland Cement, USA. Lower-carbon blended cements have been used successfully in the construc...
Measuring kiln temperatures
Temperature monitoring plays a vital role in supporting process efficiency and cement product quality. It can help to prolong the life of the kiln, detecting refractory issues or insufficiently-quenched clinker at an...
Efficient enclosed handling
Growing global cement demand calls for new levels of efficiency and environmental protection. Recent Siwertell ship unloader deliveries and orders, including projects in the USA, Europe and the Middle East, demonstra...
Three lines of defence
Digitalisation has enabled cement producers to increase the uptime of their equipment as artificial intelligence (AI) has alerted them to current or future equipment failure so swift action can be taken through the p...
Supporting the drive for decarbonisation
As cement producers continue on the path to decarbonisation and carbon capture readiness, XDH-energy discusses the interconnected themes of Environmental Compliance as a Service (E-CaaS), Energy as a Service (EaaS), ...
Better predictive power
With the cement sector now under pressure to improve the efficiency of operations, Industry 4.0 brings new opportunities. The study presented in this article provides a novel data-driven approach to predicting weighi...
Closed-loop AI optimisation
A new wave of artificial intelligence (AI) systems are quickly replacing legacy cement process controls with self-learning optimisation and sophisticated AI models. They improve quality while allowing mills and kilns...
Value from waste heat
Waste heat recovery represents a significant opportunity for cement producers to improve plant efficiency and reduce their carbon footprint. This article looks at several proven technologies for capturing and utilisi...
Gasification technology for shredded solid waste
More than two years ago Taiheiyo Engineering Corp commercialised technology and equipment for mixing and drying hot meal and sewage sludge with its Taiheiyo Thermal Reactor (TTR®).1,2 A new application of the TTR is ...
To SCR or SNCR?
While in some cases the choice between SCR and SNCR technology for NOx reduction appears straightforward, there is a middle way that enables the use of the less expensive option of SNCR technology. Lechler explains h...
Game changer in the kiln
In today’s operating environment, the refractory lining in the safety zone of a kiln needs to accommodate the requirements of alkali resistance and energy-saving properties. A new brick by Refratechnik is designed to...
Adapting calciners for decarbonisation
The drive to decarbonise cement kiln lines has led to new research that looks at the use of hydrogen and plasma flames in co-firing with biomass. While this new technology requires modifications to the calciner and b...
Tapping ultimate WHR potential
Reducing the carbon footprint of cement production and introducing captive electricity generation have become priorities for Turkish cement producer Nuh Çimento. After nine years of waste heat recovery (WHR) experien...
The future of compressed air technology
In an effort to improve the efficiency of compressed air generation, Innovatium’s PRISMA liquid air energy storage system integrates industrial energy storage with industrial compressed air. The technology is designe...
A matter of scale
While significant advances have been made in carbon capture technology for the cement industry, the issues of scale and cost loom large over the sector. A modular approach to the introduction and development of carbo...
Strength development of ternary cements
Low-clinker ternary cements containing clinker, blastfurnace slag and calcined clay are becoming increasingly important in cement markets where decarbonisation is the key to sustainable construction. Central to the p...
