Paprilox, an innovative, mill-proven technology for generating polysulfide (a chemical used to enhance pulp yield in the kraft pulping process) will be distributed by NORAM Engineering and Constructors Ltd. in the North American market, while Kvaerner Pulping AB will be the global licensee. Air Liquide will work with both licensees providing oxygen technology and marketing resources. A co-operative agreement was signed between NORAM, Kvaerner and Air Liquide to ensure a standardized product offering for Paprilox around the world. The companies will also collaborate with Paprican under the Paprican Allied Industry Program in support of on-going development of Paprilox and polysulfide pulping technology.
The Paprilox process uses a combination of lime mud, manganese oxide, and oxygen to convert the white liquor in a mill’s recaustization plant to orange polysulfide liquor. Paprilox was developed by Paprican researchers, and implemented at Domtar Espanola, a Paprican Member Company mill.
