Overcoming AF challenges in achieving carbon neutrality

18 November 2024, Published under Cement News

The operational challenges posed by climate change and energy shortages in cement production have led to a growing emphasis on adopting alternative fuels (AFs), particularly biomass, to reduce greenhouse gas emissions and improve energy security. SCG Cement and Green Solution Business’ success in integrating AFs is a notable example. However, to ensure smooth operations, potential issues such as clogging and abrasion in the production process must be proactively managed. By Palakrit Tinnakor...

Co-processing potential for the Vietnamese cement industry

23 September 2024, Published under Cement News

Vietnam’s cement industry accounts for 17 per cent of the country’s fossil fuel-derived CO 2 emissions. The drive towards net zero by 2050, supported by the Just Energy Transition Partnership (JETP) and an improved waste management paradigm, is expected to strengthen co-processing in cement kilns. By Dr Kåre Helge Karstensen and Palash Kumar Saha , Foundation for Scientific and Industrial Research (SINTEF), Norway Figure 1: non-recyclable plastic waste originating from plastic ...

Compressors for carbon capture

04 September 2024, Published under Cement News

A groundbreaking project in Norway will produce the world’s first industrial-scale carbon-free cement. It is a vital effort to decarbonise one of the hardest to manage industrial sectors, but Marco Ernst, head of sales and project management CCS at MAN Energy Solutions, argues that the true key to achieving carbon capture at scale is cost. By Dr Marco Ernst , MAN Energy Solutions, Germany Heidelberg Materials’ Brevik plant will capture and store some 400,000tpa of CO 2 when opera...

Enhancing dip tube performance at high AF rates

20 August 2024, Published under Cement News

The rise in alternative fuel (AF) utilisation in cement manufacturing challenges the lifetime of dip tubes in the lowest cyclone stages of the preheater. A new generation of the HASLE Ceramic Vortex Finder, made from precast and pre-fired ceramic elements, has been installed in a German cement plant. The solution has tripled the lifespan in the lowest-stage cyclone, achieving a full campaign, and has surpassed 3.5 years in the second-lowest stage. By Lars Andersen, HASLE Refractories, Denmar...

Meeting the low-cost NOx reduction challenge

In anticipation of stricter future emissions regulations, Taiheiyo Engineering Corp has been developing various cement kiln NO x reduction technologies. The most recent breakthrough combines the company’s new NO x reduction technology with selective non-catalytic reduction to achieve significant reduction rates at low cost. By Toshiaki Hirose, Taiheiyo Engineering Corp, Japan Taiheiyo Engineering Corp has continued to develop its NOx reduction technology to support cement compani...

LC3 and LC2 – the low-carbon business opportunity

13 August 2024, Published under Cement News

Increasing urbanisation is expected to result in a significant share of the world population living in a built environment that, unless sustainable construction materials are used, will lead to a considerable carbon footprint. The development and more widespread use of limestone calcined clay cements such as LC 3 and LC 2 is not only expected to reduce the construction footprint but also offer a business opportunity. By Dr Debojyoti Basuroy, TARA Applied Research Centre (TARC), India ...

Universities research rice husk ash as cement alternative

09 July 2024, Published under Cement News

Researchers from ten universities across the globe are exploring the feasibility of using rice husk ash (RHA) in place of cement for manufacturing activities.   The participating researchers have found the RHA has a high silica content. Therefore, when RHA is used to produce concrete, it triggers a chemical reaction with hydrates (such as calcium hydroxides). This results in the formation of supplementary products that give the mixture strength and stability, which are vital for the concr...
