Goal(s)

The knowledge of the chemicals recovery cycle in a biorefining mill using the kraft process

Responsible(s)

Gerard MORTHA

Content(s)

The unit operations of the chemicals recovery cycle in a kraft mill. Processes and unit operations, chemistry and chemicals, reactions, mass & energy balance are presented. Physiochemical phenomena and the main methods for calculation are described.

• Black Liquor evaporation: multiple-effect evaporation, characterizations
• Green Liquor production: processes, characterizations, dregs purification (clarifier, filtration)
• White Liquor production: slaking and causticizing,
• White mud purification treatments for lime recovery (reburning in a lime kiln)
• Lime kiln operation
