Conch Zongyang preheater modernisation project chosen for energy efficiency pilot

23 January 2025

China: The Conch Zongyang Line 4 preheater modernisation project, based on KHD technology, has been selected as a pilot project under the Sino-German Energy Efficiency Improvement Demonstration in Key Industries programme. The initiative will be executed by KHD, its parent company AVIC International Beijing, and Conch Group’s research and development department. Results are expected by the end of 2025.

The programme stems from a 2023 agreement between China and Germany on climate change and ‘green’ transition cooperation. The programme was announced in 2024. It evaluated 12 candidate projects before selecting the Conch Zongyang project for its integration of technologies to achieve energy efficiency and a reduction in CO₂.

This project is one of several provided by AVIC to Chinese cement producers using KHD’s pyroprocessing, grinding, alternative fuel and digitalisation solutions.

Turboden launches ORC plant in Saudi Arabia

02 October 2024

Saudi Arabia: Turboden, a subsidiary of Mitsubishi Heavy Industries, has announced its first project in Saudi Arabia — a 13MW organic rankine cycle (ORC) power plant at Riyadh Cement Company. This marks the first ORC plant in the Kingdom and the largest globally.

The plant will capture residual heat from the cement plant's clinker coolers and pre-heaters (2 kilns of 5000t/day each), offering high energy efficiency and eliminating water consumption. Sinoma Energy Conservation serves as the project's engineering, procurement and construction contractor.

General manager Andrea La Gioia said "Turboden is honoured to spearhead this groundbreaking project in collaboration with Riyadh Cement Company. With around 460 ORC plants in 52 countries, 50 in ‘waste’ heat recovery application, our ORC technology represents a game-changer in the global energy landscape, and we are proud to support the Kingdom of Saudi Arabia in its transition towards cleaner, more sustainable energy sources."

Lafarge France ignites new kiln at expanded Martres-Tolosane cement plant

31 October 2023

France: Lafarge France has ignited the new kiln at its Martres-Tolosane cement plant following a Euro120m upgrade. Local press has reported that the upgrade replaced the plant’s existing kilns and preheater tower with entirely new equipment. The new kiln has tripled the plant’s capacity, to 2.1Mt/yr from 0.7Mt/yr. Meanwhile, the new preheater tower will help to reduce the plant’s electricity consumption by over 20%. As a result of the upgrade, the Martres-Tolosane plant can now support an alternative fuels (AF) substitution rate of 60%, compared to 20% beforehand. Lafarge France aims to carry out further work to reach 85% AF substitution at the plant by 2027. Other planned projects include the installation of a carbon capture system.

Lafarge France chief executive officer François Petry said “We are going to create a research and innovation centre here dedicated to the capture of CO2, with the ambition of ultimately making the Martres-Tolosane plant net zero carbon.”

ThyssenKrupp Polysius wins CIMPOR flash activator contract

13 October 2023

Ghana: CIMPOR has appointed Germany-based ThyssenKrupp Polysius to build a 1280t/day flash activator for clay. The activator will supply calcined clay for use in the production of cement with a clinker factor as low as 50%. This can reduce the cement’s CO2 emissions by 40% compared with ordinary Portland cement (OPC). The supplier’s contract covers engineering, supply of core equipment and supervision of the project. The equipment includes parts for clay handling, a hammer mill, a flash dryer and preheating and cooling equipment, as well as storage silos. The activator will be natural gas-fired.

Polysius Activated Clay product owner Leo Fit said "Our technology is not only more environmentally friendly, but also creates cost benefits for our customers like CIMPOR. In many regions, limestone is scarce and clinker has to be imported at high cost. At the same time, suitable clay sources are available. The increasing pressure to reduce greenhouse gas emissions is leading cement manufacturers to rethink. They need an alternative that is cost-efficient and at the same time provides high-quality cement. This is exactly what Polysius activated clay offers."

Titan Group commissions upgraded Kamari cement plant

27 June 2023

Greece: Titan Group has successfully commissioned an upgrade to the pre-calciner system of its Kamari cement plant in Voiotia. Titan Group says that this will enable the 3.1Mt/yr plant to expand its range of lower carbon cements, reducing its CO2 emissions by 150,000t/yr. It also increases the plant's maximum possible alternative fuels (AF) substitution rate.

Titan Group’s Europe regional executive director Yanni Paniaras said "The completion of the Kamari plant upgrade represents a significant achievement for Titan Group. We are witnessing tangible results as our green innovation gains momentum and takes shape. This successful implementation of one of our major capital expenditure projects exemplifies our dedication to sustainable operations and strategic growth, while we continue to pursue more growth opportunities in all our active markets. We are committed to offering our customers and communities greener products and solutions, playing our part in building a sustainable future for all.”

Ciments Calcia investing Euro86m on decarbonisation at Beaucaire plant

20 April 2023

France: Ciments Calcia has announced an investment of Euro86m to further decarbonise cement production at its integrated Beaucaire plant. The subsidiary of Germany-based Heidelberg Materials has allocated a total of Euro600m towards reducing CO2 emissions from all of its operations in the country in response to a government initiative, according to The Tribune newspaper.

The current funding follows a spend of just under Euro7m on upgrades at the site, including installing a new clinker cooler that will allow for greater recovery of waste heat, and the addition of a new computer control system. Following this work, the single production line plant was restarted in early April 2023.

The next stage of investment has started with a feasibility study. If successful, a tendering process could start in the second half of 2023 with work planned to start in 2025. The company intends to renovate the plant’s electricity network, modernise the production line with a preheater and a pre-crusher and make further changes to target an alternative fuels thermal substitution rate of 75%. A third stage, involving carbon capture and utilisation and/or storage, is tentatively planned to start in 2030.

Secil Supremo Cimentos to upgrade and expand Adrianópolis cement plant

23 March 2023

Brazil: Secil Supremo Cimentos has appointed FLSmidth to carry out a pyro process upgrade at its Adrianópolis cement plant in Paraná. The Denmark-based supplier says that it plans to carry out modifications on the plant's preheater, cooler and related auxiliary equipment. It says the new equipment will expand the plant's capacity to 3900t/day, corresponding to an annual production capacity of 1.42Mt/yr. It will also enable it to increase its alternative fuel (AF) substitution rate to 40%. Secil Supremo Cimentos' AF mix consists of shredded tyres, wood and other refuse-derived fuels.

FLSmidth's head of capital sales, Jens Jonas Skov Larsen, said “We are grateful for our continued partnership with Supremo, which has consistently invested in the latest technology. As the plant was already operating an ILC five-stage preheater from FLSmidth, it was well positioned to use AF.”
