Continuous Digester Control System
Control systems continuously monitor key parameters (such as residual effective alkali, total dissolved organics, and total dissolved solids for black liquor; effective alkali, sodium sulfide, sodium carbonate for white liquor) (Connmar, 2012) to optimize the digester operation. These help reduce production losses, operating costs and environmental impacts. They also increases paper quality and quantity (Kramer et al., 2009. p.91).
