As a process engineer working in the Sulfuric plant you have been tasked to optimize the operations of the SO2 converter operating under laminar conditions. Accordingly explain the dependence of the frictional pressure loss across the converter on (i) superficial fluid velocity, (ii) particle size, (iii) fluid density, (iv) fluid viscosity and (v) voidage? Would you recommend to run the unit under laminar or turbulent conditions and why? [4]
