Metso Paper will supply a new hardwood fiberline to the Indian pulp and paper producer Tamil Nadu Newsprint and Papers Ltd. In addition, Metso Paper will supply a new bleaching process for the company's bagasse fiberline. The total value of the orders is approximately 25 MEUR. The new systems are scheduled to be started up at the beginning of 2007.
Both of the deliveries include main process machinery, pumps, field instruments and engineering. Erection and start-up supervision will be ordered separately.
Metso Paper's supply for the hardwood fiberline, from cooking through bleaching, includes a SuperBatch cooking process for pulp digesting. This cooking technology has proven to produce excellent pulp quality and to be the most flexible cooking process on the market. The new line is designed to produce 300 bdt/d fully bleached pulp of mainly eucalyptus as the raw material. The digesting process for Tamil Nadu is the 15th SuperBatch cooking system installation worldwide.
The fiberline process after cooking features TwinRoll wash presses in each stage of washing, both for brown stock and bleaching. Both knots and shives are screened out using DeltaCombi screening technology and the pulp is further delignified in a two-stage OxyTrac oxygen delignification process prior to final bleaching. For pulp bleaching a short sequence O-D-EOP-D elemental chlorine free (ECF) bleaching process is used. Altogether, the selected process represents environmentally sound modern pulping technology.
The bleaching process for the bagasse line is designed for a 500 bdt/d daily capacity, being the biggest of its kind in the world. The pulp is produced in two existing fiberlines and the new bleaching system will be common for both lines. The bleaching sequence is D-EOP-D, representing a modern ECF-process. For each stage of washing in the bleach plant, TwinRoll wash presses will be installed.
