Achievements of Chemical Recovery

  • Developed Thermal Treatment Technology for black liquor to reduce viscosity of agro black liquors and achieve high dry solids content of firing black liquor thereby increasing Thermal Energy Recovery Efficiency.
  • Developed technology for removal of silica from the black liquor.
  • Developed Direct Alkali Recovery System (DARS), a process for recovery of chemical suitable for small pulp & paper mills.
  • Developed a technology for reduction of Chlorides & Potassium in Chemical Recovery System. The technology is being upscaled for demonstration on Pilot scale.
  • Established test procedure for determination of lignosulphonate purity.
  • Identified and developed lignin purification technique to improve its performance as feedstock for clean energy and other industrial applications.
