Comparison of Residence Time Distributions of Liquid for Different Types of Input Signal using a Stimulus-Response Technique

Original language description

A stimulus-response technique was used for measuring residence time distribution of liquid phase. The evaluation of experiments depended on the type of stimulus signal. Three types of input signals were tested: the -impulse, general pulse and a general pulse in a recycle. The dispersion model was used for the interpretation of response curves for all stimuli. The model was based on the diffusion with bulk flow equation solved with the Danckwert's boundary conditions for a closed system. The analytical solution by the Fourier method contained the input function as a function of the time and initial distribution of concentration inside the vessel. The liquid-phase differential distribution function was measured in a one-impeller atypical vessel with volume of 36.35 dm3. The results of experimental stimulus-response technique were independent of the shape of the stimulus signal.
