Chloride accumulation is a serious issue in the kraft pulping process. Chloride can be selectively removed from dissolved electrostatic precipitator dust (ESP dust) in the kraft chemical recovery cycle by electrodialysis with monovalent-selective anion-exchange membranes. In a pilot-scale field test, this process was investigated (total run time, 750 h). The test was performed at about 3.5% of full scale. The process showed outstanding performance and no significant membrane fouling. In feed-and-bleed operation, chloride removal levels of 94% and 61% were tested. The energy consumption for electrodialysis is low (120 kWh per metric ton of chloride removed at a 63% chloride removal level). The process performed very well even with no feed pretreatment, polarity reversal, or membrane cleaning.
