Switzerland: A TEC has secured a contract to install a new ReduChlor chlorine bypass system at Holcim Schweiz’s Eclépens cement plant in Vaud. The supplier says that it will also fit a bypass dust handling system and upgrade the alternative fuel (AF) feeding system at the plant.

South Korea: A TEC says that it has installed and commissioned a ReduDust dust treatment plantin the chlorine bypass system of Ssangyong Cement’s Donghae cement plant in Gangwon. The ReduDust plant will recover salts from dust, enabling the producer to reuse the dust in its cement production. The supplier says that it will yield 35,000t/yr of useable dust. Ssangyong Cement already uses an A TEC Rocket Mill grinding unit in its alternative fuel (AF) production at the Donghae cement plant.

Hungary: Lafarge Hungary, part of LafargeHolcim, has awarded a contract to Germany-based Loesche subsidiary A TEC for the supply of an alternative fuel (AF) flash dryer for the 1.0Mt/yr kiln line at its Királyegyháza cement plant in Baranya county. The supplier says that the dryer will use residual hot gas from the chlorine bypass system in conjunction with a satellite burner for firing the material in the kiln. The project also includes the installation of a new AF receiving, handling, and dosing system for a second AF flow firing directly into the kiln burner. A TEC says that it will commission the project in the second quarter of 2021 after the end of the plant’s 2020/2021 winter shutdown.

Austria: Loesche subsidiary A TEC has won a contract for the supply and installation of a Flash Dryer for alternative fuels (AFs) in the kiln line of Lafarge Zementwerke's 1.1Mt/yr Mannersdorf cement plant in Lower Austria. The supplier said that it will complete the project in early 2021.

The company said, “Reaching high thermal substitution rates (TSR) requires firing of alternative fuels at the kiln burner. To reach a stable sintering zone for the required clinker quality a high fuel quality (high LCV, small particle size) is needed, otherwise the clinker quality may suffer or the TSR can be limited. With the A TEC Flash Dryer various waste heat sources can be used (clinker cooler flue gas, bypass gas, preheater gas, etc.). The material is dosed to the hot gas flow in the flash dryer and transported with this gas flow, while the moisture is evaporated, to a cyclone and a subsequent filter where the fuel is separated from the gas flow and on-line fed to a kiln burner or a satellite burner. In addition to the drying the lifting effect of the gas can separate 3D impurities which contributes in a further increase of the fuel quality.”

Austria: Stefan Kern has been appointed as the head of A TEC Group. He succeeded Wolfgang Hammer on 1 April 2018. Kern started at A TEC in August 2013 and was responsible for sales activities in Northern Europe, Eastern Europe and South Africa. In 2016 he joined the management board. Kern originally studied chemical engineering in Vienna.

The old joke about buses only coming along in pairs might just apply to Angolan cement plants this week with the inauguration of Nova Cimangola’s new 2.4Mt/yr cement plant in Luanda. It follows the announcement of the start of an upgrade project to build a clinker kiln at Cimenfort’s grinding plant in Benguela. In cement industry terms for a country with a production capacity below 10Mt/yr these projects are right on top of each other!

Nova Cimangola’s new plant has been a well-publicised project internationally. Sinoma International Engineering coordinated the line for US$400m in 21 months using components from well-known suppliers. Loesche provided a number of raw material, cement and coal mills for the project, including the country’s first vertical roller mill, as well as other components and parts. Loesche’s Austrian subsidiary A Tec also got involved as an EPCM (Engineering, Procurement & Construction Management) partner.

Cimenfort’s clinker kiln project is the third phase of a process to turn its grinding plant at Catumbela in Benguela into a fully integrated unit since it opened in 2012. Earlier phases saw the grinding plant’s capacity increase to 1.4Mt/yr from 0.7Mt/yr by using a new roller press. Work on the kiln is now scheduled to start in January 2018 with completion scheduled for 2020.

If Cimenfort makes it to clinker production they will join the country’s three main producers: Nova Cimangola, Fabrica de Cimento do Kwanza Sul (FCKS) and the China International Fund. Getting that far is by no means certain as the Palanca Cement plant project demonstrates. That scheme was backed by Brazil’s Camargo Corrêa, the owners of InterCement, and local business group Gema. However, the regulators bailed out Portugal’s Banco Espírito Santo, the financial backer of the project, in 2014 effectively killing it. Another project that has gone on the back burner is Portugal’s Secil’s plan to build a second plant next to its grinding plant in Lobito. Originally approved by the Angolan government in 2007 the project has been kicked around since then through various revisions to the local investment body. It was last reported as being under consideration by the president’s office of Angola in 2016.

Ministry of Industry figures place cement production capacity at 8.3Mt/yr compared to a consumption of 6Mt/yr. In contrast to this Secil’s parent company Semapa reported that the Angolan cement market contracted in 2016 by 25% to 3.9Mt in line with the poor state of the general economy, pushed down by poor oil prices. It blamed the decrease in cement consumption on a halt in public infrastructure spending and the negative effect that local currency devaluations had on clinker imports and other incoming raw materials. With the International Monetary Fund (IMF) forecasting economic growth to pick up for Angola in 2017, improvements in the construction and cement sector are expected by Semapa but they hadn’t been seen so far during the first quarter of the year.

The government’s keenness to describe its cement industry as ‘self-sufficient in cement’ mimics calls from other African countries like Nigeria. The Angolan government banned cement imports in 2015, with the exception of certain border provinces, and this has continued into 2017. However, the ban hasn’t stopped the country exporting cement to its neighbours. Earlier this year the head of Cimenterie de Lukala in the Democratic Republic of Congo blamed the closure of his company’s integrated plant on imports from Angola.

All of this leaves an enlarged local cement industry waiting for the good times to come again. In the meantime, exporting cement and clinker no doubt seems like a promising proposition. In the middle of this are projects like those from Cimenfort and Secil that are looking decidedly dicey in the current economic environment. These companies may have just missed the bus to make their upgrades happen. Still, if they wait around long enough, their chance may come again when the market revives.

Austria: A TEC Group has appointed Wolfgang Hammer as its new managing director. The former Global Sales Manager at the company replaces Hans Joachim Grieb who retired on 31 March 2016. Stefan Kern has been appointed his deputy. He is responsible for the markets Northern Europe, Eastern Europe and South Africa. These appointments are effective from 1 April 2016.

Austria: Ghassan Broummana has been appointed managing director of A TEC Group from 1 October 2013. As managing director Broummana will be responsible for sales and marketing within the A TEC and A TEC GRECO group.

Broummana started his career in 1987 designing and starting-up cement plants. In 1996 he joined Holcim Group Support in Switzerland where he developed and implemented various corporate initiatives. In 2004, he moved to Holcim's subsidiary in Thailand, Siam City Cement, to start up a new business unit preparing alternative fuels and raw materials from industrial and household waste.

In 2009 Broummana joined the managing committee and executive committee respectively of Holcim's subsidiaries in India, ACC and Ambuja Cements. Here he restructured Techport, the unified technical support service centre that provides expertise to both ACC and Ambuja Cements with the aim of improving the efficiency and effectiveness of over 25 integrated cement plants and grinding stations and managing all the major capital expenditure projects for both companies.

Broummana holds a Diploma in Electrical Engineering and a Diploma in Wirtschafts-Ingenieur (MBA) from the University of Dortmund. He has also completed a 'Program for Executive Development' at IMD-Lausanne and 'Advanced Management Program' at Harvard Business School, US.
