Abstract: A double liquid distribution device is suitable for a fractionating or wash column comprising a high collector tray connected to a manifold support via at least two longitudinal liquid downflow ducts. The manifold support supports at least two series of transverse tubular manifolds and feeds liquid respectively to the first series of manifolds via a first longitudinal duct and to the second series of manifolds via a second longitudinal duct. Each manifold includes distribution orifices in its under face suitable for distributing the liquid onto the top face of the packing bed. The two longitudinal liquid downflow ducts are connected together in a low portion by a communication device fitted with a valve having controlled opening suitable for allowing the liquid to be transferred between the two longitudinal ducts in controlled manner.
