Understanding of the dispersion zone in the phase separation tank and the residence time of the dispersed phase in it
Thread Content
Dear sea friends, I have been doing theoretical calculations on phase separation tanks recently, and I would like to discuss with you the concept of the dispersion zone. 1. Typically, the dispersion zone is set with H=0.1 m; thus, the residence time t of the dispersed phase in this zone is given by t=H*Ai/Qd/2. The dispersion zone represents the layer where the two phases are mixed, and the calculated residence time determines the minimum time the mixture must stay in the phase-separating tank. Is this understanding correct? 2. The material inlet pipe is usually not located at the two-phase interface; if the inlet pipe is positioned higher up, how should the time that the light phase spends in the phase separation tank be calculated? Please give me your advice
Additional: Does anyone know where the empirical data suggesting that the height of the dispersion zone should be 0.1 m comes from? Thank you
