SNCR: when the equation no longer holds
There are plants where selective non-catalytic reduction (SNCR) does not achieve the expected DeNO X results for no apparent reason. Often a look at the chemical processes in the background provides a clue as to why successful denitrification is failing. By Karin Koglbauer, DyCarnica, Austria. Figure 1: chemical DeNOx behaviour-ammonia vs urea (© DyCarnica) Selective non-catalyt...
CO2NTESSA’s net-zero vision
The CO 2 NTESSA project will implement an innovative carbon capture (CC) technology at NEXE’s cement plant in Našice, Croatia. The existing plant will be modified based on the polysius® pure oxyfuel process, enabling...
Business models for utilisation of non-recyclable plastics in the Indian cement industry
Co-processing of plastic and other municipal solid wastes provides a safe and cost-effective way of dealing with waste in India and supports the country’s drive to adopt a circular economy approach. By Dr Gaurav Bha...
Carbon capture optimisation: add heat, reduce risk
While a range of carbon capture (CC) technologies are available to the cement industry, not all are a suitable option in terms of cost and risk. Ramboll looks at the benefits of an integrated amine-based solution. By...
Heidelberg Materials’ journey to net-zero
Heidelberg Materials is investing in multiple projects to achieve its ambitious target of reducing its CO 2 emissions by 47 per cent by 2030. From its first carbon capture and storage (CCUS) project at the Brevik pl...
Ironing out the carbon emissions of clinker production
The use of iron-rich industrial wastes can provide one of the pathways to decarbonising the global cement industry with high-ferrite cement types embodying less CO 2 than their ordinary counterparts. By Cecilia Pesc...
Towards Germany’s first fully-decarbonised cement plant
Heidelberg Materials’ new GeZero project will completely decarbonise cement production at the Geseke plant in North Rhine-Westphalia, Germany. The first of its kind project will establish a full carbon capture and st...
London arbitration of maritime disputes and cement trading
Arbitration is often used for the resolution of commercial disputes, particularly in the context of international trade and shipping. This article provides a brief introduction to the relevance of London arbitration ...
Unlocking the power of waste heat
Waste heat is the largest unused energy resource in the world. Harnessing this untapped potential can be a game-changer. A flexible and proven technology, modular organic-Rankine cycle (ORC) waste heat recovery turns...
Geopolymer cements to address the GHG challenge
Mineral carbonation is being explored within the cement and concrete industry to chemically convert CO 2 emissions into stable minerals leading to permanent CO 2 storage within cementitious materials. Teesside Univ...
CLEANKER’s calcium looping progress and prospects
For the last few years, Buzzi SpA has been hosting a pilot project to demonstrate the efficiency of calcium-looping CO 2 capture technology for a cement plant. Results from the project’s nine experimental campaigns ...
Unlocking hydrogen’s power for greener transportation
Decarbonising concrete and cement transportation poses challenges – hydrogen may be the missing puzzle piece given payload and uptime benefits. The industry should take this opportunity to create ecosystems that depl...
Keeping cement moving sustainably
As supply chain sustainability becomes a key priority for organisations, CEMEX is committed to investing in innovative heavy-duty transport solutions. Dave Hart, supply chain director of CEMEX UK and France, explains...
Europe’s calcined clay debut
At the Saint-Pierre-la-Cour cement plant in France, Holcim has developed and commissioned its own patented technology to produce calcined clay with the lowest-possible CO 2 footprint, 100 per cent alternative fuel u...
Lubrication: a grease of cake?
Applying the correct lubricant at the correct time can significantly increase the life of roller bearings and avoid costly downtime of cement plant equipment. Lubricant producers have developed the necessary products...
