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), and waste heat recovery for increased peak load demand and flue gas cleaning for optimal CO 2 capture. By Xavier d’Hubert, XDH-energy. Figure 1: Environmental Compliance as...
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...
ACCSESS for CCS projects
Carbon capture, utilisation and storage (CCUS) is an important pillar of HeidelbergCement’s carbon neutrality roadmap. As part of Project ACCSESS, the company will be the first to pilot CCUS technology in eastern Eur...
Aggregates go carbon negative
There is a consensus that, to reach net zero by 2050, the cement industry must embrace carbon capture, utilisation and storage (CCUS). This article looks at the potential of CCUS for the treatment of cement residues ...
Addressing AF myths
Existing misconceptions about the use of alternative fuels (AFs) continue to form a barrier to increased thermal substitution rates in cement plants. Specialist AF producer N+P addresses these myths and provides proc...
Rohožník White is green
White cement is used to create some of the greatest architectural landmarks that attract attention all over the globe. In Europe white cement is only produced in a few places, including at the Rohožník cement plant i...
