Andritz has received an order from Cartulinas CMPC S.A in Maule, Chile, to upgrade the complete bleaching system at its mill in, Maule, Chile, which processes 100% radiata pine for the production of softwood BTMP (bleached thermo-mechanical pulp). Start-p of the upgraded bleaching system is scheduled for the fourth quarter of 2017.
The ANDRITZ scope of supply encompasses:
- Components for the existing Andritz screw press that feeds the installed Andritz HC mixer
- A new screw conveyor system to the peroxide high-consistency (PHC) bleaching tower
- A new pulp screw press including dilution conveyor
- A new MC pump to feed the pulp to the existing storage tower.
The bleaching system upgrade by Andritz will lead to an increase in BTMP production from 30 to 37 air dried metric tons/hr., while at the same time substantially reducing energy consumption per ton of pulp produced.
Cartulinas CMPC S.A., Planta Maule, is one of the leading board producers in South America, with customers in more than 40 countries worldwide.
