AN ANALYSIS OF THE STEADY STATE BEHAVIOR OF A MIXER-SETTLER EXTRACTION SYSTEM
The steady state behavior of a multi-component mixer-settler extraction system has been analyzed by adopting a mixing cell model with the individual Murphree stage efficiency parameters.
Empirical equations for the chemical equilibrium of HNO3-UO2（NO3）2-TBP system have been derived and incorporated into the model equations. Nonlinear Component Block Successive Relaxation (NCBSR) method executed through an Approximate Newton Raphson routine has been proposed for the solution of nonlinear steady state system equations and compared with the other methods.
The model and the derived equilibrium relations were found to be successfully employed in depicting the steady state behavior and the proposed NCBSR method was proven for its effectiveness in comparsion with the other methods.
