International technology Group ANDRITZ has received an order from ITC Bhadrachalam, Telangana Province, India, to supply a BCTMP fiber line with a production capacity of 300 tons per day. The new plant will be the first mechanical pulping line in India for production of high-brightness board grades. Start-up is scheduled for the third quarter of 2016.
The order comprises the supply of a fiber line with 2-stage refining to ensure lowest possible energy demand and high fiber quality, as well as a two-stage bleaching system with minimum chemical consumption. Six counter-current washing stages are to reduce contaminants so that exceptionally clean pulp can be produced at low chemical oxygen demand. In addition, the ANDRITZ washing technology keeps fresh water consumption and effluent levels to a minimum.
The new fiber line uses available synergies with the existing eucalyptus pulping line at ITC Bhadrachalam. The effluent will be evaporated, the clean condensate re-used, and the white liquor from the kraft mill will be used as alkali source in the new BCTMP fiber line.
