Hydrodynamics of trickle bed reactors (TBRS) packed with industrial catalyst using advanced measurement techniques
… using advanced measurements techniques of Gamma-ray densitometry (GRD) and Optical fiber probe and conventional measurement techniques of high-frequency differential pressure transducer and load cell. Two different reactor sizes of bench and pilot plant scale were used. Bench-scale TBR …

Studies of multiphase distribution and flow in bubble/ slurry bubble columns with /without internals and advanced sustainable construction materials using sophisticated measurement techniques
… in a Slurry Bubble Column Reactor (SBCR) using gamma-ray densitometry (GRD) and point optical fiber probe (OFP) techniques. The obtained results indicated that increasing the solids loading increased the solid holdup and decreased the liquid holdup.</p><p>However, the gamma-ray computed …

Investigation of local velocities and phase holdups, and flow regimes and maldistribution identification in a trickle bed reactor
… optical fiber probe was put at. The non-invasive gamma-ray densitometry (GRD) technique has been implemented for the first time in trickle bed reactor as in online monitoring technique to identify flow regime, gross maldistribution and liquid distribution. The GRD technique was able to identify …

Scaleup and hydrodynamics study of gas-solid spouted beds
… variables on their hydrodynamic parameters. Gamma Ray Densitometry (GRD), a non-invasive radioisotope based technique, was developed and demonstrated to montior [sic]on-line the conditions for the scale-up, flow regime and spouted beds operation. The solids holdup in spout region increases …
