Influence of solution temperature fluctuation on performance of dynamic regeneration process
A dynamic model of the regenerator was developed to investigate the influence of solution temperature fluctuation on regeneration performance.An experimental platform of solution regeneration system was built to verify the model.The simulation was conducted to investigate the effects of average temperature,fluctuation period,and amplitude of the solution temperature on the range of solution mass fraction and average regeneration rate.Results show that the average temperature of the solution has the most significant impact on the average regeneration rate,while the fluctuation amplitude has the greatest influence on the range of solution mass fraction.When the temperature fluctuation period of the solution is 0.5 h,the average regeneration rate shows an increase with the rise of the fluctuation amplitude.With a fluctuation period of 2.0 h,the average regeneration rate is primarily affected by the average temperature of the solution.The range of solution mass fraction increases with the fluctuation period increases when the temperature fluctuation amplitude is small.Whereas,when the amplitude is large,the mass fraction range exhibits a descending trend with the increase in the period.
