Abstract
This article presents a study for investigating impact of the measurement approach on the quality of gamma scanning density profile in tray type columns using experimental and computational evaluations. Experimental density profiles from the total and the photopeak count measurements, as two approaches in gamma ray column scanning technique, has been compared with the computational density profile from Monte Carlo simulation results. We used a laboratory distillation column of 51Â cm diameter as an illustrative example for this investigation. 137Cs was used as a gamma ray source with the activity of 296Â MBq (8Â mCi), with a NaI(Tl) detector. MCNP4C Monte Carlo code has been used for simulations. The quality of the density profile in the photopeak count approach is relatively within 155-204% better than that of the total count approach for experimental results. The same comparison for simulation results leads to a relative difference within 100-135% for the density profile.
