Veolia to Deliver Cutting-Edge Chemical Recovery Technology at One of the Largest Pulp Mills in the World

摘要

The state-of-the-art chloride removal system is designed by Veolia Water Technologies to optimize the recovery process in the industry of transformation of hardwood cellulose into pulp for textile fibres and fine paper making. Rising paper consumption in Asia and growing global demand for more environmentally friendly fibres for the apparel industry are driving the increase in pulp making capacity to convert renewable fibres into a variety of fine paper products and viscose staple. In tropical Indonesia, the Riau province is a major hub for the forestry industry and is home to the operations of the Asia Pacific Resources International Holdings Limited (APRIL) Group, the world's second-largest producer of bleached hardwood kraft pulp. APRIL-owned Riau Andalan Pulp & Paper (RAPP) produces pulp of the highest purity at one of the world's largest paper mills in Kerinci (Riau). As a result, RAPP performs pulping washing and cleaning steps which produce an organics-rich liquid stream. When this liquor is burned in the recovery cycle, it generates renewable power that helps the mill become energy self-sufficient. Over time, however, the process creates chloride and potassium accumulation which, if not tightly controlled, causes corrosion and boiler fouling increasing maintenance costs.
