摘要
A computational model, based on finite difference solution of partial differential equations, is developed to describe thermal and solute concentration behavior within a recuperative parametric pumping column. Experimental data for the dilute NaCI solution-mixed bed ion exchange resin system are used to evaluate parameters in the model, which successfully simulates the time- and position-varying column profiles during an experimental NaCI-H2O separation run. To model accurately this system in which interphase solute transfer is strongly intraparticle diffusion-controlled and alternating in direction, intraparticle profiles must be taken into account. © 1969, American Chemical Society.
