Abstract:
A sub-critical centrifuge was fed with a 53%-47% (w/o) mixture of “Freon-12- Freon-22” to survey tail scoop distance from rotor wall effect and feed flow rate effect on gas hold up and rotor wall temperature. In this case, 20 experiments in four tail scoop distances (6.12, 5, 4, and 3mm) and five feed flow rates (10, 15, 25, 35, and 40 g/h), were designed. The results showed that, rotor wall temperature distribution in vertical direction was decreasing from top cap to bottom cap. Temperature of all points of rotor wall increased monotonously with feed flow rate increment due to uniform raise of gas hold-up and number of gas molecule-rotor wall impacts, while temperature difference between top cap and bottom cap was invariant. Temperature of top of rotor wall raised with tail scoop distance decreasing, due to increasing of drag force exerted on the gas by tail scoop, which causer to increase temperature difference between top cap and bottom cap. Temperature difference between top cap and bottom cap was only dependent to physical characteristic of gas centrifuge like tail scoop position. Highest and lower rotor wall temperature was respectively 316 and 305 k at 3 and 6.12 mm tail scoop distance and 40 and 10 g/h feed flow rate.
