The commissioning of the modernised line five is scheduled for the fourth quarter of 2023.

South Korea: Halla Cement has awarded a supply and engineering contract to Germany-based KHD Humboldt Wedag for an upgrade of line 2 at Okke plant. KHD will supply a new Pyroclon R type calciner, with a Pyrotop type mixing chamber, and a 4.2m x 15m Pyrorotor type combustion reactor. Other equipment being provided includes: a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage five cyclones with new high-efficiency cyclones; and a new kiln inlet chamber with orifice. Erection and commissioning of the modernised production line is scheduled for the first quarter of 2024.

This latest project marks the second installation of a Pyrorotor at Halla Cement’s Okke plant. The installation of line 3 at the site is currently ongoing with commissioning scheduled for the first quarter of 2023. Overall, this will be KHD’s ninth installation of a Pyrorotor in South Korea.

The Pyrorotor has been promoted to cement plants as a way of using low-quality alternative fuels with minimal pre-processing. It offers a thermal substitution rate of over 85% and will also allow the Okke plant to reduce its NO_x emissions. The installation of the new Pyroclon R type calciner and the high-efficiency cyclones in the lowest preheater stages will also provide the production line with an increase in efficiency due to an overall pressure drop reduction in the entire preheater.

Mexico: GCC has signed an engineering, procurement and construction (EPC) contract with ThyssenKrupp Polysius for an upgrade to its integrated Samalayuca plant to increase clinker production capacity, raise the usage of alternative fuels and reduce emissions. The project includes the engineering, supply and modification of the preheater, including cyclones, and an extension to the calciner, with the installation of a Prepol SC-S type system to increase the utilisation of alternative fuels. The work also includes fitting a Polytrack type clinker cooler and the installation of a bypass system. The project will begin in 2022 with operations scheduled to start in the second quarter of 2023.

Senegal: France-based Fives has detailed the equipment that it will supply for its construction of a new 6500t/day kiln line at SOCOCIM Industries’ Rufisque cement plant in Dakar Region. The company says that it will supply a preheater, in-line Preca calciner, kiln, TGT filter and Pillard Novaflam burner.

SOCOCIM Industries’ parent company Vicat’s chair and chief executive officer Guy Sidos said “Vicat Group renews its partnership with Fives Group through this major project of building a new line with a strong local dimension, employing local workers and contractors.” He added “This plant will eventually eliminate the use of fossil fuels, reduce our energy consumption and support Senegalese local development, making a higher quality product while doubling our production capacity.”

Peru: FLSmidth has secured a contract for the supply of a new pyro line for Cementos Pacasmayo’s Pacasmayo cement plant near Lima. The new line will give the plant an additional production capacity of 0.6Mt/yr. The supplier says that it plans to install a Cross-Bar cooler, low-NO_x calciner, Jetflex burner, equipment for dosing and feeding and process automation. FLSmidth says that the upgrade will reduce the plant’s energy consumption and open new opportunities for the use of alternative fuel (AF).

FLSmidth’s head of projects and upgrades and senior vice president Anders Josefsen said “We are very excited to work with Cementos Pacasmayo on this project – not only on growing the business, but doing it in a sustainable way. The new line will be equipped with a state-of-the-art pyro system including several of our MissionZero solutions. With this, Pacasmayo makes a significant investment in future-proofing its production.” He added “The Pacasmayo project is a prime example of our capabilities within process design: ensuring the integration to an existing plant, while also demonstrating our ability to deliver equipment that meets demands for energy and fuel efficiency.”

India: UltraTech Cement plans to increase the production capacity at its Maihar cement plant by 50%. Denmark-based FLSmidth will carry out the expansion project, which also involves the installation of a new calciner and JetFlex burner, along with other pyroprocessing equipment.

Denmark: Aalborg Portland has awarded A Tec a contract to upgrade its Cement Kiln 87 in Aalborg. It has ordered two calciners for its 4500t/day semi-dry kiln system that was commissioned in 1988. The calciners will be designed and delivered during the kiln’s annual stop in February and March 2017. Commissioning is planned for the spring of 2017. The upgrades are intended to increase production of Ordinary Portland Cement on the line.

A Tec intends to adapt the flow pattern of the calciner system in a way to improve the operational behaviour of the system. The design will be configured for the usage of 100% solid alternative fuels with low emissions. Additionally, the number of kiln stops due fall through cyclone blockages should be reduced. A Tec will conduct the engineering, supply the equipment and will be responsible for errection and documentation.

The new calciner system will be equipped with the A Tec Post Combustion Chamber (PCC) for the optimised mixture of fuels and combustion air in the end section of the calciner. The PCC was specially developed for the achievement of complete combustion of alternative fuels at high substitution rates.
