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 how cement producers can benefit from its high-efficiency SNCR technology. By Dipl Ing Claus Fritze, Lechler, Germany. Figure 1: structure of the APC Process Proven te...
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...
Sludge co-processing progress and prospects
China has significant potential for the development of cement kiln co-processing technologies of municipal sludge and other solid wastes. In this article, a dry sludge disposal project at a cement plant in Guangdong,...
Buckets of flexibility
In the cement industry high-capacity bucket elevators are used to lift a wide range of bulk materials, including raw mix, limestone, coal, raw meal, clinker and cement. Gambarotta Gschwendt recently received an order...
Beyond primary measures
Under tightening emission legislation, it may be time to consider new technologies and products to remain in compliance. Denmark-based Umicore offers a variety of catalysts for the removal of NO x , NH 3 , dioxins, C...
Graphene’s future potential
Reducing carbon emissions in the cement industry is a top priority, but how to achieve that is the subject of considerable research and development. For First Graphene Ltd and Fosroc International, graphene shows gre...
LC3 in codes and standards
Reducing the carbon footprint of the concrete industry is a priority in the face of global warming. Limestone calcined clay cements (LC 3 ) provide one of the best options to reduce CO 2 emissions. For optimal imple...
