A flow pattern study in the Hyl I packed bed reactor

Flow distribution pattern in the Hyl I reactors of FT Krakatau Steel has been studied using a 1 : 10 scale model of the reactor, water as the modelling fluid and KMn04 tracer injection and measurement at sixteen different locations in the model. The packed bed materials investigated comprised three mixtures ( average pellet diameters : 6.30 mm, 7.85 mm and 9.00 mmplaced in the model reactor with concave and convex top surfaces, respectively. The results of the water model study of the Hyl I reactor clearly indicate a nonideal flow pattern of the fluid, affected by top surface geometry and pellet mixtures used
