Abstract:
A study of uncertainty in gamma ray transmission measurement of single beam tomography is presented. The radial density distribution of the FCC (fluidized catalytic cracking) catalyst in experimental riser is shown in measured and calculated data. Discrete models are proposed to describe data and for a better understanding of density distribution measurements. Validation procedure for the measurement models and uncertainty evaluation were carried out.
