PURPOSE:In case of extraction of some material contained in a new liquid with solvent such as super critical fluid, etc., which two liquids flow counter- currently in the packed tower to prevent channeling of a solvent and to enhance contact efficiency of the solvent and a raw material, by providing the titled solvent disperser at the bottom of packed layer to disperse and supply the solvent into packed layer. CONSTITUTION:A disperser consists of two sheets of plates 12, 14 partitioned a space room. A solvent is fed into the space room through a supply line 2 and supply ports 13 of the second plate 14 of the disperser through a supply line 9. Then the solvent is dispersed and fed to the upper part (packed layer) through the blowout ports 10 provided to the first plate 12 of the disperser. On the other hand, the residue liquid alter extraction of a raw liquid is passed through conduits 11 which connect perforates of the above-mentioned both plates 12, 14 of the disperser and allow the residue liquid of extraction to flow and uniformly drawn to the lower part and drawn out to the outside through a discharge line 4. As a result, channeling of the solvent supplying into packed layer is prevented and contact efficiency of the solvent and the raw liquid can be enhanced.
