For Immediate Release
Plainfield, Illin., Sept. 23, 2004 - CMPC Celulosa S.A. (CMPC), a subsidiary of Empresas CMPC S.A., has selected HPD to supply a black liquor evaporation system for the new Santa Fe Line 2 Project in Chile. With an evaporation capacity of 1050 tons/hour, the seven-effect evaporation system will be supplied on a turnkey basis at the mill located in Nacimiento, Chile. When the project is completed in 2006, the Line 2 will produce 780,000 t/a of Bleached Eucalyptus market pulp (BEK).
HPD will provide complete system design, engineering, equipment, project management, installation and start-up services. The equipment includes a seven-effect, eleven-body evaporation system with a foul condensate stripping system, a methanol rectification system, NCG (non-condensable gas) collection, a CRP (Chloride Removal Process) system, and storage and heavy liquor tanks.
The evaporation system is designed to process black liquor from 14.4% to 80% total solids and will utilize tubular falling film technology. A switching system used above critical solids will provide for a continuous wash of one of the four first-effect concentrator bodies. The system is designed to minimize total steam and power usage, as well as minimize boil-out requirements and maintain high on-stream delivery of 80% liquor to the boiler.
The Santa Fe mill expansion has a planned start-up of September 2006.
CMPC Celulosa, S.A. is a major international softwood and hardwood pulp producer. The Santa Fe mill produces bleached hardwood eucalyptus pulp, which is used primarily in the production of printing, writing and tissue paper.
HPD introduced the first tubular falling film black liquor evaporator train in 1985, which was followed by a significant shift in the pulp and paper industry. The majority of multiple-effect black liquor evaporation projects now use falling film technology.
