Overcoming AF challenges in achieving carbon neutrality18 November 2024, Published under Cement NewsThe 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... |

Compressors for carbon capture04 September 2024, Published under Cement NewsA 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 rates20 August 2024, Published under Cement NewsThe 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... |

Universities research rice husk ash as cement alternative09 July 2024, Published under Cement NewsResearchers 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... |
