  • Objectives
  • Determine properties of black liquor and smelt
    under gasification conditions
  • Model high-temperature, entrained flow black
    liquor gasifiers
  • Understand and suggest optimization strategies
    for liquor injectors in entrained flow gasifiers

Thermal Conductivity
Density
Adapted from Adams
Black liquor density decreases linearly with
temperature and increases linearly with solids
content within thermodynamic phases.
Thermodynamic transitions occur at 65 and 80
solids. A second order model is used to predict
liquor density.
Density, viscosity, and thermal conductivity are
strongly dependent on the solids concentration in
the liquor and decrease with temperature. Good
correlations for density and viscosity have been
developed. These correlations are specific to
certain liquors as well as pulping and cooking
conditions. Smelt properties lend themselves
less well to such predictions.
