【Abstract】 Gas hold-up was measured for foaming and non-Newtonian solutions in a 0 112 m diameter bubble column with a draft-tube of different size The gas hold-up was determined using the liquid overflow method The influence of superficial gas velocity and the ratio of the draft-tube diameter to column diameter on gas hold-up was analyzed更多还原
