- During this quarter, work has finally resumed on the black liquor solubility experiments, but no new data have been generated. The crystallization experiments with inorganic model solutions have been completed, and crystallization experiments with kraft black liquor have been started. The Annular Test Cell apparatus is now fully operational, while construction of the falling film evaporator pilot plant is nearly complete. Startup of this unit is planned for late in Quarter 6. In the CFD model development work, the relaxation of simplifying assumptions in the falling film model have been completed, and expressions were developed to estimate film velocity/film Reynolds number relations. Also, thin film data taken for a range of conventional fluids were compared to predictions using selected methods, and attempts were initiated to extrapolate to approximate black liquor evaporator conditions.
