First Industrial P&P Chloride Removal

Location: USA
Completed: March 2008

Highlights: High chloride concentrations at pulp mills cause recovery boiler plugging and corrosion, reduce steam generation, drive up energy costs, and result in expensive shutdowns. Together with ECO-TEC Inc., NORAM provided a novel system that selectively removes chlorides from the black liquor cycle. It employs a special amphoteric sorption resin in a modified ion exchange column, capable of removing both anions and cations simultaneously from solution. Chloride removal rates exceeding 90%, and CO3 and SO4 make-up losses of less than 4% have since been achieved at the mill.
