KIMA Process Control to supply kiln cooling system for Cementa's Slite cement plant
17 November 2022Sweden: Germany-based KIMA Process Control has secured a contract for the supply of a kiln shell cooling system for Cementa's Slite cement plant in Gotland. 88 water jets will deliver centimetre-precision cooling for the 55m-long kiln, while IR pyrometers measure temperatures over areas of 10cm2. According to KIMA Process Control, the equipment can avoid unnecessary cooling of the kiln shell, conserving the heat energy supplied by the main burner.
The new cooling system will eliminate the use of energy intensive electric fans, slashing 1700t/yr in CO2 emissions, according to the supplier. It said that noise emissions will also 'drastically' decline as a result of the upgrade. The system's operating costs are reportedly 98% less than those of the plant's existing fan system.
The supplier said that the new equipment will 'bring the cement plant in Slite an economic benefit in the shortest possible time.' It said "For the cement industry, this project represents a new milestone in terms of best available technology in the operation of rotary kilns."
Cemex increases nine-month 2022 sales and income
27 October 2022Mexico: Cemex sold 47.8Mt of cement in the first nine months of 2022, down by 5.3% year-on-year from 40.5Mt in the same period of 2021. Despite this, its consolidated revenues rose by 8%, to US$11.7bn from US$10.8bn. The group's cost of sales grew by 12% to US$8.09bn from US$7.25bn, and its operating earnings before interest, depreciation, taxation, depreciation and amortisation (EBITDA) dropped by 6.6%. Nonetheless, contributions from discontinued operations led to net income growth of 72%, to US$987m from US$574m.
Cemex said that higher prices in local currency terms drove sales growth across all of its regions. As a percentage of sales, costs grew to 70% from 68%, mainly on account of energy price rises. Operating EBITDA fell across all regions apart from Europe, the Middle East, Africa and Asia (EMEAA), where it rose by 2.5% to US$524m from US$511m. Cemex noted Europe's 'remarkable resilience' in implementing 'double-digit' price increases to increase earnings, while also crossing a threshold of 40% in CO2 emissions reduction from its 1990 baseline.
Philippines: Cemex subsidiary Solid Cement is installing a new US$356m, 1.5Mt/yr line at its Antipolo cement plant. When operational in April 2024, the line will increase the plant’s capacity by 79% to 3.4Mt/yr. Over the first four months of the project since March 2022, Solid Cement invested US$197m in silos and mechanical installation. The new 1.5Mt/yr line will use Low Temperature Clinker technology to reduce its CO2 emissions, and will also recycle waste hot gases for raw materials drying.
Solid Cement is building the plant using 6000t of its own Vertua reduced-CO2 cement, which it says will further reduce its net carbon footprint by 564t.
Philippines president and CEO Luis Franco said “We will maintain our active role in supporting the development of this nation, as we have done in the past 25 years.”
World: Three cement producers - Cemex, Dalmia Cement and Holcim – are founding members of COP26’s First Movers Coalition public-private partnership. The partnership plans to use its global purchasing power to create markets for emerging CO2 emissions reduction technologies, in order to accelerate and scale collective impact towards the global realisation of emissions reduction targets.
The coalition expects technologies currently on the market to account for 82% of CO2 emissions reduction before 2030 and 50% before 2050, while it expects future technologies to account for 15% before 2030 and 46% before 2050.
Kerala government announces plan to reduce cement prices
04 November 2021India: The government of Kerala plans to increase its cement production in order to help lower the price of cement in the state. The Times of India newspaper has reported that the state owns 10% of its cement industry. It plans for state-owned Travancore Cements to increase grey cement, white cement and wall putty production at its Nattakom grinding plant in Moolavattom. Its other cement company, Malabar Cement, previously increased its cement production.
The state government also convened a meeting of private sector cement producers in order to discuss the possibility of a reduction in the price of cement.
Systems Change Lab report accuses cement industry of failing to make progress towards 2030 climate change target
28 October 2021World: A Systems Change Lab report on the state of climate change action has warned that the global cement industry is making insufficient progress towards its 2030 climate change targets and that a step-change in action is required. It recorded the carbon intensity of global cement production at 635kgCO2/t in 2018 with the 2030 target of no more than 370kgCO2/t. The rate of change over the previous five years was reported as being 2.9% but an annual rate of change of 22.5% would now be required to meet the 2030 target.
It also noted that emissions intensity from the cement industry had actually increased slightly in recent years. It reached this conclusion by using a different methodology from the Getting the Numbers Right (GNR) project. Instead it estimated the global emissions intensity by using global data on process emissions and energy data from the International Energy Agency and the GNR.
The report said that the cement sector would need to go beyond traditional mitigation options such as improving energy efficiency and switching fuels to meet its climate commitments. However, carbon capture utilisation and/or storage (CCUS) and novel cements were described as costly and immature. In its view, “Decarbonisation in the long term thus will depend on significant investments in research, development, and demonstration, alongside efforts to create a demand for low-carbon cements and policies to support investment in decarbonisation technologies.” It described both strategies as, “not yet fully mature in terms of technology development, costs and scaling.” The ‘critical enablers’ it identified to help the cement sector meet its target included stricter regulations, increased demand for low-carbon cement and investment in pilot and industrial scale projects looking at novel cements.
Overall, the report said that change towards averting climate change across 40 key areas in power generation, buildings, industry, transport, land use, coastal zone management and agriculture was not happening fast enough and that none were on track to meet their respective 2030 targets. Change was happening but not at the required pace. Systems Change Lab is a collaboration between the High-Level Climate Champions, Climate Action Tracker, ClimateWorks Foundation, the Bezos Earth Fund and World Resources Institute.
Finland: Wärtsilä’s sales fell by 6% year-on-year to Euro3.18bn in the first nine months of 2021 from Euro3.39bn in the corresponding period of 2020. It increased its order intake by 11% to Euro3.58bn from Euro3.24bn. The company’s cash flow from operating activities fell by 12% to Euro360m from Euro407m. It expects that demand for its offering will increase ‘considerably’ year-on-year in the fourth quarter of 2021.
The supplier announced that it will aim to achieve carbon neutral operations and to provide a product portfolio which will be ready for zero carbon fuels by 2030. It published a report entitled Front Loading Net Zero on how production economies can make savings while managing the renewable energy transition. The report concludes that full decarbonisation before 2050 will be financially viable if properly supported by governments and energy companies.
President and CEO Håkan Agnevall said “These new targets demonstrate our commitment to a sustainable future. Our aim is to support our customers on their decarbonisation. Our products, solutions, and services will meet the stringent environmental requirements, and the fuel flexibility and fuel efficiency of the engines powering these sectors are key to enabling the transformation.” Agnevall added “Naturally, we also need to do our part as an organisation and minimise our own environmental footprint.”
China to set cement production energy efficiency benchmark
25 October 2021China: The government plans to implement a benchmark level of energy efficiency for cement plants by 2025 in order to realise its national goal of no CO2 emissions growth by 2030 and carbon neutrality by 2060. Local press has reported that the government has yet to set a specific benchmark for the cement industry. The corresponding figure for aluminium production will be 13,000kWh/t.
Sweden: Cementa has announced that its Stockholm cement terminal will no longer receive deliveries of its Slite brand cement and will instead begin solely stocking the company’s fly ash cement from 1 December 2021. The producer says that the transition will reduce the carbon footprint of the terminal’s products by 30,000t/yr. Slite cement will continue to be available from the nearby Köping and Oxelösund cement terminals.
FLSmidth to supply 11,500t/day kiln line for Shree Cement’s upcoming Nawalgarh cement plant
12 October 2021India: Shree Cement has hired FLSmidth to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill. The project focuses on sustainable productivity and emissions control. Shree Cement has opted for JetFlex burners to give the lowest possible nitrous oxide emissions for various fuel types.
Shree Cement managing director Prashant Bangur said “Based on the experience of working with FLSmidth on the installation of a 9,000t/day pyro system at the Raipur, Chhattisgarh, cement plant earlier this year, we felt confident about approaching Carsten Riisberg Lund and his team regarding the Rajasthan project.” He added “Being recognised as a Sustainability Champion by the World Economic Forum is a testament of our emphasis on sustainability at every stage of our operations. The new line will push that agenda even further in terms of lowering the benchmarks on energy consumption and emissions, and thereby reducing our environmental footprint.”
FLSmidth also supplied a second OK mill for Shree Cement’s operations in Kolkata, West Bengal.
