Vietnam: Vicem (Vietnam Cement Corporation) Hoang Thach Cement has ordered a type LM 59.3+3 CS vertical roller mill for the Hoang Thach cement plant in Hai Duong province. The mill has a transmission power of 6200kW and it is able to grind 250t/hr of Ordinary Portland Cement (OPC) to a fineness of 3600 Blaine. Commissioning is scheduled for later in 2018.

The scope of supply also includes an external reject system, dedusting equipment, a material conveying system and multi-chamber silos with two packaging systems downstream. The system is equipped with a LOMA LF20 heater run on heavy oil, which produces around 30,000Nm³/hr of hot gas at a temperature of 450°C. In addition, Loesche is supplying the equipment for the power supply and distribution and the grinding plant control. A particular challenge of the project has been supplying new equipment for an existing plant with limited space.

Mexico: Elementia’s sales benefitted from its Mexican cement business in 2017. Its net sales rose by 35% year-on-year to US$1.37bn in 2017 from US$1.02bn in 2016. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 24% to US$236m from US$191m.

Highlights of the company’s year included integrating Giant Cement’s assets into the company, the start-up and allocation of additional volume from the cement plant in Tula, Mexico and the expansion of the cement division in Costa Rica through the installation of a grinding plant that is expected to start operations towards the end of the first half of 2018.

Elementia’s Mexican cement division sales rose by 44% to US$236m from US$164m. However, the sales of its US division fell by 7% to US$231m from US$249m. The company blamed this on the year being a ‘transitional’ period where it conducted regular maintenance works that interrupted production.

US: CarbonCure has demonstrated an integrated CO₂ capture and utilisation (CCU) process from cement for concrete production in January 2018 at Cementos Argos’ Roberta plant in Calera, Alabama. The consortium - comprising Carbon Cure, Sustainable Energy Solutions (SES), Praxair, Cementos Argos and Kline Consulting - says it is the world’s first project to collect cement kiln CO₂ for subsequent utilisation downstream in concrete production and construction.

CO₂ emissions from the Roberta cement plant were captured by SES’ Cryogenic CO₂ Capture technology, transported by Praxair and reused in Cementos Argos' Glenwood, Atlanta concrete operations equipped with CarbonCure's CO₂ utilisation technology. The concrete manufactured with the waste CO₂ from the Roberta cement plant was then used in a local construction project in the greater Atlanta area. Design partners and fellow members of CarbonCure’s Carbon XPRIZE team such as LS3P Architects, Uzun + Case Structural Engineering, and Walter P Moore Structural Engineers completed the end to end integrated solution by creating demand for CarbonCure concrete products in the marketplace. Kline Consulting oversaw the commissioning and reporting of the industrial demonstration.

The project was an extension of Team CarbonCure's participation in the US$20m NRG COSIA Carbon XPRIZE Challenge, which incentivises and accelerates the development of integrated CCU technologies and new markets that convert CO₂ emissions from coal and natural gas power generation into valuable products.
