Commercially-proven, brownstock washing technology can increase production rates of bleached and non-bleached kraft pulp through more efficient washing and recovery systems. At the same time, it can reduce effluent loadings and lower bleach plant chemical requirements. Brownstock washing technology can provide operational cost savings with minimal capital expenditures, using traditional or newly designed equipment, with or without oxygen delignification.
- Increased production rates
- Improved washing efficiency
- Lower bleach plant chemical requirements
- Reduced effluent loadings
Other benefits of adding CO2 include reduced bleach plant chemical requirements through lower chemical oxygen demand carry over, lower dilution factors, improved sheet consistency and higher sodium recovery levels.
