6 Objective Reduce the fiber loss, chemical and water consumption in flotn Reduce fiber contamination ti Increase ink and sticky removal efficiency i Improve the process control in flotation ti deinking operation
7 Concept Development Laboratory and Pilot Results
8 Problems Related to Surfactant Use in Flotation Deinking Surfactant adsorption: Reduces ink hydrophobicity (ink removal) Reduces liquid surface tension Reduces fiber-fiber bonding Surfactant carryover: Creates foaming problem on paper machine Environmental effects Strength loss in paper Difficult to control the froth Surfactant cost

10 Conventional Flotation Deinking Surfactant mixed into pulp feed Nonselective flotation
11 Surfactant Spray Flotation Deinking Surfactant Layer Surfactant Layer
12 Advantages of Surfactant Spray High ink removal efficiency Reduced adsorption of frother agent on ink particles Reduce fiber loss Foam layer is generated after bubbles reach the top of flotation cell: reduce the possibility of fiber entrainment Less fiber contamination Reduce direct contacts t between fibers and frother agent Less Surfactant carryover Effectively control the froth Reduce surfactant cost Reduce water loss and water contamination
13 Conventional Flotation Process: Multiple stages Cell 1 Cell 2 Cell 3 Cell 4 Cell 5 Too much foam and high fiber loss Too little foam and poor ink removal
