Published Mar 31, 2005 14.00.00 +2 GMT

The Brazilian pulp producer CENIBRA (Celulose Nipo-Brasileira S.A.) has selected Metso Paper's chemical pulping technology for the modernization of the fiber line no. 2 in their Belo Oriente pulp mill in the state of Minas Gerais, Brazil. The value of the order is over 20 MEUR. The start-up of the upgraded fiber line is scheduled for May 2006.

The scope of Metso Paper’s EPC-delivery comprises upgrading of the fiber line system from brown stock washing up to bleached stock storage. After the modernization, the line will be capable of producing daily 2,000 tons of bleached eucalyptus pulp with a bleaching sequence O2-DHT-EO-D-P. The existing oxygen delignification stage will be modified to a two-stage OxyTrac process and Metso Paper’s TwinRoll wash presses will be installed in the new washing stages of the fiber line.

The two-stage OxyTrac process enables a higher kappa reduction in the oxygen stage without sacrificing pulp quality. This will lower the chemical consumption in the bleaching process. The new generation TwinRoll wash presses feature increased capacity together with improved washing efficiency.

The investment is targeted to improve the mill's economy and to reduce its environmental impact. The mill's total annual pulp production will increase from 940,000 tons up to 1,140,000 tons.

Celulose Nipo Brasileira S.A is fully owned by JBP (Japan Brazil Paper and Pulp Resources Development Co., Ltd.) which is a group of 17 Japanese companies. Oji Paper and Itochu are among the owners with a 39.5% share each.
