Application of Residence Time Distribution for Measuring the Fluid Velocity and Dispersion Coefficient
Most studies on residence time distribution (RTD) have focused on the tail of the RTD curve, and very little attention has been paid to the effect of white noise on the measured results. The aim of this work is to study the effect of white noise on the calculated parameters with different data proce...

| description | Most studies on residence time distribution (RTD) have focused on the tail of the RTD curve, and very little attention has been paid to the effect of white noise on the measured results. The aim of this work is to study the effect of white noise on the calculated parameters with different data processing methods. The anti‐disturbance abilities of the moment method and the least squares method are compared. The results show that the anti‐disturbance ability of the least squares method was better than that of the moment method. As a result of peak overlapping in the RTD curve of a loop reactor, the moment method cannot be used to calculate the fluid velocity and dispersion coefficient. Experiments show that the least squares method is still applicable in a loop reactor.
The effect of white noise on the calculated parameters of residence time distribution (RTD) is investigated with different data processing methods. The anti‐dis‐turbance abilities of the moment method and the least squares method are compared. The least squares method is found to be most applicable in a loop reactor. |
