Metso Paper introduces ZeTrac - the innovative way of bleaching
Published Feb 02, 2001 00.00.00 +2 GMT
Metso Paper is proud to introduce ZeTrac, the improved HC ozone bleaching process.
The development of this new process started less than two years ago and is the culmination of over one decade of accumulated Metso know-how working with this technology. The first installation is now in operation at Burgo Ardennes in Belgium. Two more mills have already commissioned the new process, Oji Paper Nichinan in Japan and VCP Jacarei in Brazil.
The main benefit of the HC ozone process is the opportunity to replace large amounts of chlorine dioxide with ozone and maintain pulp strength. This will have a significant positive impact on production costs. The ZeTrac process is naturally very beneficial from an environmental point of view as it means substantial reductions in effluent volumes.
Furthermore the capital outlay for the new system is considerably lower than for earlier HC ozone installations. ZeTrac requires no refiner or plug screw feeder and one washing stage is eliminated. This will also significantly reduce both the operating and maintenance costs of the system.
At the ATIP Congress & Exhibition on October 17-19, 2000 in Bordeaux, the patented process was granted the "Prix Spécial du Jury" in the ATIP Innovation Contest.
Altogether, the introduction of this system represents a major opportunity for producers of both ECF and TCF pulp to improve their efficiency and reduce the environmental impact from their mill operations.
