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.
