| Abstract Fructose-glucose aqueous solution is separated via semi-continuous thermal parametric pumping. The experiment indicates that the technology can be used to separate the sugars continuously and effectively in a simple equipment. When parametric pumping cycles to a certain degree, a limiting separation appears. Reflux ratio, feed concentration and cycling time have effect on the separation.In this paper, we present a mathematic model involving the resistance of mass transfer and solve it numerically by using the method of characteristic line. The algorithm is simple with high calculating speed.The model can agree with the experimental results by introducing into it the modifying factor of mass tramsfer coefficient. |
