Germany: ThyssenKrupp Industrial Solutions’ Polysius division says that it has been commissioned by Buzzi Unicem, HeidelbergCement, Schwenk Zement and Vicat to build a pure oxyfuel kiln system at the Mergelstetten cement plant as part of the Cement Innovation for Climate (CI4C) project. No dates of the start of construction or final project commissioning of the industrial trial have been disclosed. CI4C was originally formed in 2019.

The Polysius pure oxyfuel process is a new type of clinker production process in which the otherwise normal ambient air is replaced by pure oxygen in the kiln combustion process. One advantage of the technology is that atmospheric nitrogen is eliminated from the clinker burning process leading to much higher concentrations of CO₂ in the exhaust gas compared to a conventional kiln. As such the process aims to concentrate, capture and reuse almost 100% of the CO₂ produced in a cost-effective manner. The medium-term goal is to further process the captured CO₂ with the help of renewable energy into products such as kerosene for air traffic.

Germany: ThyssenKrupp says that the four cement producer members of Cement Innovation for Climate (CI4C) are preparing to launch an industrial-scale trial of its Polysius Pure Oxyfuel carbon capture and storage (CCS) process. The renewably-powered process produces ‘refuel’ synthetic fuels such as kerosene for aviation.

Senior Proposal Manager Markus Sauer said,“CI4C and ThyssenKrupp are currently investigating the use of our polysius pure oxyfuel technology in a demonstration plant. Working with our long-standing customers, we would be delighted if we could demonstrate the efficiency of our technology for the first time on an industrial scale. By using this technology, the cement industry could significantly reduce its process-related CO₂ emissions and thus make an important contribution to climate protection.”

Bolivia: Antonio Pino, Vice Minister of Hydrocarbons, says that a new gas pipeline will have to be built to supply the Potosí cement plant at Chiutara. This may delay the start of the new plant to as late as early 2022, according to the El Potosí newspaper. The 1.3Mt/yr integrated unit was previously planned to start operation in February 2020.

The project was supported by the country’s previous government administration through the creation of Empresa Publica Productiva Cementos de Bolivia (ECEBOL. The plant is being built by Sociedad Accidental Imasa Polysius, a joint venture created by Polysius and Imasa.

Bolivia: Empresa Publica Productiva Cementos de Bolivia’s (ECEBOL) new integrated cement plant at Caracollo in Oruro has been inaugurated. President Evo Morales attended the event for the 1.3Mt/yr plant, according to the Correo del Sur newspaper. The project had an investment of US$306m and it was built by a consortium of Sacyr, Imasa and Polysius.

Bolivia: Empresa Publica Productiva Cementos de Bolivia’s (ECEBOL) at Caracollo in Oruro will start commercial operation in August 2019. The US$306m plant will have a production capacity of 1.3Mt/yr, according to Radio FM Bolivia. A consortium of Sacyr, Imasa and Polysius have worked on the project.

US: CalPortland has commissioned a new cement grinding mill and distribution system at its Oro Grande cement plant in California. The US$58.5m project includes the construction of the finish ball mill and two new cement shipping lanes with two new distribution silos. It completes a partial plant modernisation program that was originally completed in 2008, prior to the acquisition of the facility by CalPortland. The Oro Grande cement plant was purchased from Martin Marietta Materials in mid-2015.

“The addition of this modern finish mill and efficient distribution system allows the plant to operate to the best in class standards as originally designed. It will help provide the industry with the additional supply required for necessary rehabilitation and rapidly developing infrastructure in California and Nevada,” said Steve Regis, Senior Vice President Corporate Services, CalPortland.

The project began in January 2018 and was constructed by general contractor ThyssenKrupp and sub-contractor TIC (The Industrial Company), in collaboration with CalPortland’s Engineering Services team.

The mill is a Polysius two compartment mill with production capability of around 180t/hr. It is equipped with motor, mill and separator technology as well as cement cooler design technology. The system also employs mechanical conveyance (bucket elevator) to convey finished product to the new silos, reducing its energy requirements. These additional systems are being added to the Oro Grande plant.

Bolivia: The Potosí cement plant being built by Empresa Publica Productiva Cementos de Bolivia (ECEBOL) hopes to produce its first cement bag by December 2019. Work on the plant is over half-complete, according to the El Potosí newspaper. Construction work on the main platform of the preheater tower is continuing and civil engineering work on the mill has been completed. Most of the equipment for the project has been supplied. The plant is being built by Sociedad Accidental Imasa Polysius, a joint venture created by Polysius and Imasa. The US$240m unit will have a production capacity of 1.3Mt/yr when finished.

Bolivia: The head of Sociedad Accidental Imasa Polysius, a joint-venture created by Polysius and Imasa, Zubim Andrade, says that a cement plant that company is building in Potosí is more than 45% complete. The half-way mark is expected to be met by the end of October 2018, according to the El Potosí newspaper. Over 900 people are working on the project and most of the equipment for the unit has arrived. The 1.3Mt/yr cement plant has a cost of around US$240m.

Bolivia: Empresa Publica Productiva Cementos de Bolivia’s (ECEBOL) new 1.3Mt/yr plant at Caracollo in Oruro is scheduled to start operations in the first half of 2019. A consortium of Sacyr, Imasa and Polysius are working on the US$244m project, according to the La Patria newspaper. A US$2m electrical sub-station is also being built to support the plant.

Bolivia: Ground removal work at the Potosí cement plant is expected to start in August 2017. Imasa, Valoriza and Polysius will prepare the 40-hectare site, according to the El Potosí newspaper. The plant has a proposed production capacity of 1.3Mt/yr and it has been budgeted at US$241m.
