A six blade turbine (Da = 3 ft) is used to disperse hydrogen gas into a slurry reactor containing methyl linoleate at 90 C and 60 lIb, / in gauge with 1 percent suspended catalyst particles (Ds = 50 um, pp = 4 g/cm'). The reactor diameter is 9 ft and the depth is 12 ft. The gas flow rate is 1800 std ft'/min. The oil viscosity is 1.6 cP and density is 0.84 g/cm at 90 C. The reactor is fully baffled. What agitator speed is needed to give 5 hp / 1000 gal during the reaction? (b) What is the power consumption with gas flow on and with gas flow off?
