Liquid-liquid contacting apparatus

摘要: A compact, multi-stage, co- or counter-current liquid-liquid extraction apparatus includes first and second mixer-settlers which share a common wall. Each of the comprises mixing chamber having an agitator mounted therein, upper lower settling chambers, baffles between chambers respectively. The liquid media to be contacted in each mixer-settler are supplied from dispersion flows upwardly downwardly into baffles. Disengaged lighter medium out mixer-settler, over weir whose length exceeds half wall, while disengaged heavier one corresponding next mixer-settler. In form also overflows outlet pass on another passes through pipe leading operation 1:1 phase ratio can maintained despite different (e.g. 10:1) feed rate apparatus.
