Cartago, Holcim (Costa Rica)
- 3,000 tpd capacity
- Contract date July 2002
- Very low CO2 production per ton of cement
Holcim Costa Rica, a subsidiary of the Holcim Group, entrusted Fives FCB with a contract for the supply of a complete 3,000 tpd production line for its Cartago plant, in Costa Rica.
Thanks to the innovative technologies developed by Fives such as the multi-fuel precalciner FCB Zero-NOx Preca and a 110 tph FCB Horomill® grinding mill, this new line, which replaces the 1,650 tpd existing one, benefits from a substantial improvement in terms of thermal efficiency and energy consumption.
In July 2002, Holcim Costa Rica, a subsidiary of the Holcim Group, embarked in a very determined campaign to reduce its greenhouse gas emissions, entrusted Fives with a contract for the supply of a complete 3,000 tpd production line for its Cartago plant, in Costa Rica.
In addition to the 3,000 tpd clinker burning line, equipped with the precalciner FCB Zero-NOx Preca using alternative fuels (liquid and solid industrial waste), the plant comprises a 110 tph cement grinding plant equipped with a FCB Horomill® unit. Thanks to these innovative technologies developed by Fives, the new production line benefits from a substantial improvement in thermal efficiency and from a lower electric consumption of the cement grinding.
One year after the plant commissioning in October 2004, Holcim gave its first report on the plant’s environmental performance: in 2005, the new unit emitted only 545 kg of CO2 per ton of cement, which is 37% less than the average figure of 870 kg usually noticed by cement manufacturers.
The precalciner FCB Zero-NOx Preca operated most of the time in ‘Zero-NOx’ emission and NOx emissions, measured on outlet from the preheater running on 100 % petcoke, were less than 500 mg/Nm3 at 10% O2.
Thanks to the Fives technologies, Holcim exceeded not only the objectives set by the Kyoto protocol but also those it had defined itself.
In the Holcim Cartago plant (Costa Rica), Fives supports its client in operations and maintenance for the Horomill® grinding plant through a yearly Technical Services Agreement.
