【Abstract】 The average liquid-drop diameter(Sauter diameter) in liquid-liquid turbulence system and residence time distribution(RTD) of fluids in solid-liquid mixing system were determined in five geometrically similar nitration reactors installed double coil under different conditions. The empirical formula of Sauter diameter and flow model of RTD were proposed and the relevant parameters were determined by experiments. The experimental results show that there is the optimum pilot volume of the nitration reactor in heterogeneous nitration reactor scale up. [WT5HZ]更多还原
