Abstract
In this paper, a new simple method for determination of flow parameters, axial dispersion coefficients
DL and Péclet numbers Pe was presented. This method is based on an accurate measurement
model considering pulse tracer response. Our method makes it possible to test the character of gas
flow motion and precisely measure flow parameters for different pressures and temperatures. The idea
of combining the transfer function, numerical inversion of the Laplace transform and optimisation
method gives many benefits like a simple and effective way of finding solution of inverse problem and
model coefficients. The calculated values of flow parameters (DL and/or Pe) suggest that in the considered
case the gas flow is neither plug flow nor perfect mixing under operation condition. The obtained
outcomes agree with the gas flow theory. Calculations were performed using the CAS program type,
Maple®.
