New clinker production lines in the US
27 July 2022Congratulations are due to the National Cement Company of Alabama and Vicat for the inauguration of the new production line at the Ragland cement plant in Alabama. The event took place on 21 July 2022.
The US$300m project was originally announced in late 2019. It then took two years to build with construction starting in January 2020. Key features include a raw vertical grinding mill, a new roller mill, a five stage preheater tower, an automatic clay storage system, a 78m tall homogenisation silo, an alternative fuels storage area for tyre-derived fuel, sawdust and wood chips, a laboratory and a new control room. The new kiln was previously reported to have a clinker production capacity of 5000t/day and it will add up to 2Mt/yr of cement production capacity to the plant. ThyssenKrupp signed up as the principal equipment supplier in 2019 and H&M was the main contractor. The production line is expected to reduce energy consumption by one third. Further change is scheduled with a switch to production of Portland limestone cement (PLC) from Ordinary Portland cement (OPC) by the start of 2023.
Vicat has repeatedly noted its affection for the plant as it was the first cement plant the group purchased outside of France, back in 1974. Indeed, Vicat’s group chair and chief executive officer Guy Sidos personally managed the Ragland plant in 2001. However, rather more prosaic reasons may also have been behind the decision to expand Ragland. According to United States Geological Survey (USGS) data, Alabama, Kentucky and Tennessee’s cement shipments grew by nearly 5% year-on-year to 7.1Mt in 2019 from 6.8Mt in 2018. Shipments are up by 3% year-on-year to 2.5Mt in the first four months of 2022 and the three states were the fifth largest region in the US for cement shipments in April 2022. A shortage of cement was also reported in Alabama in April 2022.
The other big US-based cement plant expansion is Lehigh Hanson’s US$600m upgrade to its Mitchell plant in Indiana. It also celebrated a milestone this week with a ‘topping out’ ceremony to mark the placement of the final section of steel for the stack. Another recent achievement here was the completion of a 169,000t storage dome supplied by Dome Technologies. The supplier says that the 67m diameter and 48m tall dome is the second largest clinker storage facility in Europe and North America, after one it previous built in Romania in 2008.
The Mitchell K4 project was announced in mid-2018 and then ground breaking began in late 2019. However, the start of the coronavirus pandemic delayed construction in early 2020 before it restarted in September 2020. The revised commissioning date was then moved back about half a year to early 2023. The key part of this project is that it will replace the plant’s three current kilns with just one. The new production line will increase the site’s production capacity, reduce energy usage and decrease CO2 emissions per tonne of cement. It was reported by local press back in 2018 that the project would increase the plant’s cement production capacity to 2.8Mt/yr. The project has been linked to supplier KHD with CCC Group as the contractor.
It’s fascinating to see two major new upgrades to cement plants emerging in a mature market like the US and during an unprecedented event like the emergence of coronavirus. No doubt compelling tales will emerge of how both teams coped with managing nine-figure capital expansion projects as a global public health emergency unfolded. The US market has been on a roll in recent years, despite all the uncertainty in the world, and so far it doesn’t seem to be slowing down. With luck both of the projects feature above have timed their opening right.
Mexico: Beumer Group has won a contract to supply Cooperativa La Cruz Azul’s cement plants with 14 new 5500 – 6000 bag/hr palletisers. The cement company made the decision to modernise palletising operations at its plants following a law change requiring cement to be packaged in 25kg bags, instead of 50kg, from the start of 2023. Beumer Group plans to deliver the first five palletisers in the third quarter of 2022. The other nine machines will follow by 2023.
The supplier said “Cruz Azul and Beumer Group have had a trustful and successful partnership for decades. The system provider has convinced with its highly developed and sustainable technology and a sophisticated concept, which will enable the cement manufacturer to achieve the required performance in its packaging terminal” It continued “Covid-19 presented a particular challenge in this project. Due to the pandemic, it was not possible for Beumer experts to be on site with the customer in person. All concepts were discussed, debated and agreed online and with the support of the local group company in Mexico City.”
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.”
US: Vicat subsidiary National Cement Company of Alabama inaugurated its new US$300m production line at its Ragland cement plant on 21 July 2022. Local press has reported that the line includes a new rotary kiln, equipped for alternative fuel (AF) use.
President Spencer Weitman said “This puts us into the next 40 or 50 years. And it’s prolonged the life of the plant to move us forward into the next century hopefully.”
El Salvador: Holcim El Salvador has officially inaugurated an upgrade to its Maya cement plant. The company has invested US$11.6m towards increasing clinker production capacity by 0.45Mt/yr at the unit. Total cement production capacity of the plant has increased to 1.9Mt/yr from 1.2Mt/yr previously. The Maya cement plant previously reduced production levels significantly in 2008 in response to the global financial crisis at the same time. Oliver Osswald, Region Head of Holcim LATAM, attended the inauguration. The event was also used to launch Holcim’s new corporate branding in the region.
US: Dome Technology has commissioned a 169,000t dome at Lehigh Cement's Mitchell cement plant in Indiana. The dome is equipped with three reclaim tunnels, enabling 83% live reclaim.
Dome Technology sales manager Lane Robertssaid “It’s a colossal project. It’s one of our bigger domes as far as storage capacity goes."
UK: Cemex UK has commissioned a new 25kg plasticcement bag packing line at its Rugby cement plant in Warwickshire. The line will operate alongside an existing paper bagging line.
Cemex UK's packed cement sales manager Graeme Barton said “The packaging of our products is under routine scrutiny to meet customer demand and reduce waste. We have listened to what our merchants and customers need, and by investing in higher, more reliable capacity, Cemex can now meet the demand from the market in peak months with greater confidence. In turn, our stockists can meet their customers’ requirements by supplying what they need, in a format that works better for them. Our merchants and end-users are already seeing the immediate benefits of the new packaging by reporting fewer breakages in branch and onsite – which helps to cut down on waste."
Holcim Deutschland’s Lägerdorf cement plant to receive oxyfuel kiln and carbon capture system
18 July 2022Germany: Holcim Deutschland announced a planned upgrade to its Lägerdorf cement plant’s kiln on 14 July 2022. The producer will install a second generation oxyfuel kiln, which uses an air separation unit to supply oxygen directly, emitting CO2-rich flue gas. A new carbon capture system will supply captured CO2 to a synthetic hydrocarbons plant, which will produce methanol for other industrial applications. The upgrade will result in the capture of 1.2Mt/yr
of CO2 emissions and make Lägerdorf one of the world’s first carbon neutral cement plants, according to Holcim Deutschland.
The project, called Carbon2Business, was among four cement plant projects and 13 other EU-wide projects to win a share of a US$1.81bn EU Innovation Fund funding pot. CEO Thorsten Hahn acknowledged that the awarding of funds was ‘good news for Holcim and all partners working with us to decarbonise cement.’ He said “Climate change means cement change.”
Egypt: Misr Cement Qena commenced automated cement production at its Qena cement plant in early July 2022. The automation systems also cover plant maintenance processes. Misr Cement Qena awarded a technical management contract for the plant to Arab Swiss Engineering Company in June 2021.
Misr Cement Qena said "This step came in line with the company’s growth strategy to reduce operating costs and maximise asset utilisation in order to meet current challenges."
Four Vietnamese cement line projects cancelled
13 July 2022Vietnam: High costs have resulted in the cancellation of four planned new integrated cement lines by a local cement producer. Viet Nam News has reported that the producer in question presently faces costs of US$59.9 - 64.1/t cement, with a net loss of US$8.55 - 10.30/t. Coal prices are US$237/t, more than triple those at the start of 2022 of US$85.5/t. Gypsum and diesel prices rose by 50% over the first half of 2022. The producer reportedly attributed the coal price rise to the effects of the Covid-19 conflict and the Russian invasion of Ukraine.
