(Press Release) -
Weyerhaeuser Company, one of world's largest providers of forest products, has awarded a project for upgrades to the spent pulping liquors evaporation system at its New Bern, North Carolina mill to HPD, a Veolia Water Solutions & Technologies company. This project is part of an optimization effort of the recovery operations at the mill that includes upgrades to the existing recovery boiler. HPD will reconfigure the existing evaporation system and provide additional equipment to increase spent pulping liquors throughput, increase spent pulping liquors firing concentration, and remove chloride and potassium from the recovery cycle.
The upgraded evaporation system will provide an increase in firing solids to the recovery boiler to 80% TS utilizing Enhanced Forced Circulation evaporation technology. Installation of this technology at the New Bern mill will not only increase the concentration of spent pulping liquors, but will also allow reconfiguration of the existing system to eliminate the frequent washing and plugging historically experienced. Enhanced Forced Circulation is a proprietary technology from HPD that allows higher concentration of spent pulping liquors while maintaining very good heat transfer efficiency and minimizing fouling.
HPD will also provide a CRPTM (Chloride Removal Process) system as part of this project to complement the improvements to the recovery boiler with reduced chloride levels in the liquor. The CRP system is an effective method to purge non-process elements (NPE's) such as potassium and chlorides from the recovery cycle while recovering valuable sodium. Currently, precipitator ash is purged to the sewer system at the New Bern mill to maintain chloride and potassium levels. The integration of the new CRP system will allow control NPE's by removing them from the cycle while minimizing soda and sulfate losses.
The selection of HPD by the Weyerhaeuser Company is based on previous, successful projects utilizing both Enhanced Forced Circulation technology and the Chloride Removal Process.
