US: Two LafargeHolcim US cement plants have been awarded the Environmental Protection Agency’s (EPA) Energy Star award. The EPA recognised the Holly Hill plant in South Carolina and the Devil’s Slide plant in Morgan, Utah.

“Receiving the Energy Star award this year at two sites is an affirmation of the hard work all our employees are devoting every day to meeting our environmental goals,” said John Stull, chief executive officer (CEO), US Cement.

This recognition is the eighth time the EPA has awarded both the Holly Hill and Devil’s Slide plants with the Energy Star award since 2009.

Belgium: HeidelbergCement has hosted a ground breaking ceremony for the Calix carbon capture pilot at CBR’s cement plant at Lixhe. The ceremony itself took place at the Liège Oupeye Water Treatment Plant near Liège as part of the inaugural Innovation in Industrial Carbon Capture Conference. The two-day event, which took place on 7 – 8 February 2018, was organised by the Low Emissions Intensity Lime And Cement (LEILAC) Consortium, a European Union (EU) Horizon 2020 backed research and innovation project.

Construction work on the pilot at the cement plant is scheduled to start imminently. The project will test Calix’s carbon capture technology for two years at an operational cement plant. The technology has previously been used in the magnesite calcining sector.

Over 130 delegates from industry, academia and government attended the conference. The agenda was designed to encourage discussion and knowledge sharing across key stakeholder groups with a strategic interest in innovation in carbon capture technology. As part of the programme, the wider challenges faced by the cement and lime sectors in Europe were also explored focusing on how EU industries can contribute to reaching climate change targets, the role of innovation and company entrepreneurship and a knowledge exchange fair on technology.

The LEILAC consortium, which consists of representatives from the lime and cement industries, technology and engineering providers and research institutes, has set up as an industrial project securing Euro12m in EU funding in order to demonstrate technology to reduce carbon emissions from cement and lime industries.

Turkey: Dal Teknik Makina has completed an upgrade project on Kiln Line 1 at Nuh Çimento in Kocaeli. Key features of the project included increasing the line’s production capacity, decreasing its energy requirements, making savings on power consumption and lowering the exit temperature of the clinker. The work has increased the plant’s production capacity to 3400t/day from 2800t/day. Other benefits of the update include decreasing the specific heat consumption of clinker to 740kcal/kg clinker from 870kcal/kg clinker, reducing electrical power consumption by 7kWh/t and increasing the raw mill capacity to 185t/hr from 160t/hr. The exit temperature of clinker was also reduced to 55^oC plus the ambient temperature.

This project involved the design, manufacturing and erection of the pre-heater tower cyclones group, kiln feed transport system, clinker cooler, kiln hood, removing of dust cyclone at tertiary air duct, cooler vent fan modification, main bag filter duct modification and kiln inlet seal and commissioning of the system.

The first part of the upgrade project was the modification of the pre-heater tower, which as a result reduced the pressure drop, improved heat transfer and separation efficiency, and heat consumption. The second part of the project was the retrofit of the grate cooler. The clinker cooler, kiln hood, cooler fans and cooler vent fan were replaced by Fons Technology International. In this part, kiln hood, cooler vent, exit pipe of waste heat recovery (WHR) unit and tertiary air duct were modified as well. The third part was to replace the horizontal duct of main bag filter inlet with an inclined one in order to avoid dust accumulation. The last step was the replacement of the pneumatic kiln feed by bucket elevator.

The project followed Dal Teknik Makina’s Filter-To-Filter Pyro-Process Concept.

France: Fives FCB has been awarded an engineering, equipment supply and supervision of works contract for the replacement of a kiln at the Lumbres cement plant. The work covers replacing the downstream shell of the 42.2m kiln, including the tyre. The project is part of the cement producer’s plan to adapt Kiln 5 at the site for the installation of a new clinker cooler.

Burkina Faso: Cimburkina has started upgrading its Kossodo cement grinding plant. The US$2.85m project will centre on the installation of a new mill. This will double its production capacity to 2Mt/yr, according to the Sidwaya newspaper. Other works will include a new 2000t limestone silo and a new bagging unit. The new mill is scheduled to start production in December 2018.

The plant, a subsidiary of Germany’s HeidelbergCement, produces two types of cement: CEM II 42.5 R and CEM II BL 32.5 R. Clinker for production comes from the group’s Scantogo plant in Togo.

Ivory Coast: Jean-Claude Brou, the Minister of Industry and Mines, has inaugurated a new mill at LafargeHolcim Ivory Coast’s plant at Abidjan. The new mill has increased the unit’s production capacity to 2Mt/yr, according to the Agence Ivoirienne de Presse. LafargeHolcim Ivory Coast re-used a ball mill from a Spanish cement plant that was dismantled and shipped to Abidjan. The mill uses a 4.5MW motor and the cement producer says it is the largest horizontal ball mill in French-speaking West Africa. The project cost US$28.5m.

India: JK Cement has received approval for an upgrade at its Mangrol cement plant near Chittorgarh in Rajasthan. The plant will have an investment of US$312m, according to Accord Fintech. Following the expansion the plant will have a cement production capacity of 4.2Mt/yr. Cement grinding will be supported by units in Uttar Pradesh and Gujarat.

Saudi Arabia: Finland’s Wärtsilä has provided an update on a three-year asset management deal for Northern Region Cement’s (NRC) power plant at its Turaif plant signed in October 2017. Wärtsilä will continue to be responsible for the operation and maintenance of the power plant and to ensure the reliability and availability of its operations. This agreement is an extension of Wärtsilä’s previous service agreements for NRC’s power plant. The first service agreement with NRC was signed in 2008.

“We are proud to be able to continue our 10-year cooperation with NRC. By having full responsibility for the operation and maintenance of NRC’s power plant, we have been able to ensure reliable operations, optimised fuel consumption and reduced maintenance costs for NRC,” said Haidar al Hertani, managing director, Wärtsilä Saudi Arabia.

The agreement covers all aspects of operating and maintaining NRC’s power plant, including the day-to-day operation of the power plant as well as preventive and predictive maintenance. Wärtsilä’s Customer Centre in Dubai remotely monitors the power plant’s condition. Wärtsilä has also carried out electrical and automation services to improve the performance and extend the lifespan of NRC’s power plant.

The 62MW power plant is equipped with nine Wärtsilä 32 engines and provides energy for NRC’s Turaif cement plant. The cement plant has two production lines, producing nearly 10,000t/day of cement.

US: United States Lime & Minerals grew its sales revenue in 2017 due to higher business from its oil and gas services and industrial customers. Total revenue grew by 4% year-on-year to US$145m in 2017 from US$139m in 2016. The producer raised the price of its lime and limestone products in 2017.

“Demand for our lime and limestone products in the fourth quarter and full year 2017 remained steady. In addition to the St Clair replacement kiln project, we continue to seek innovative ways to enhance efficiencies at all of our facilities so we can compete in what remains a challenging pricing environment,” said Timothy W Byrne, president and chief executive officer of United States Lime & Minerals.

India: A contract worker has been killed in an accident at Ambuja Cement’s Maratha plant in Maharashtra. An apparent electrical problem in a wagon loading machine caused the incident that crushed the 32 year old worker, according to the IndustriAll union. The union says that mechanical problems had been reported previously in the plant’s packing unit. LafargeHolcim, the owner of Ambuja Cement, reported 86 fatalities at its sites in 2016.
