An apparatus for separating impurities from a liquid by a non-dispersive contacting of a liquid-liquid reactive systems, said liquids being immiscible with each other, which comprises a cylindrical column separated into a first stage and a second stage, a plurality of modules of packed metallic fibers mounted in the first stage of said column on a support, a first distributor provided in the first stage of the column for distributing a first liquid located above said support such that said first liquid completely wets said fibers by capillary action and forms a film thereon, a second distributor fitted at a bottom portion of the second stage for distributing a second liquid containing impurities on to the metallic fibers, wherein said second liquid flow co-currently with said first liquid so that the impurities present in said second liquid react with said first liquid and dissolve therein and a separator connected to a bottom of said column for separating the first liquid and purified second liquid.

A process for separating impurities from a liquid by a non-dispersive contacting of liquid-liquid reactive systems which comprises distributing a first liquid over a support consisting of packed metallic fibers mounted in the first stage of a two stage liquid distributor so that the entire support is completely wetted by said first liquid by capillary action, said first liquid forming a film over said support, distributing separately, a second liquid containing impurities to be removed, said second liquid being immiscible with said first liquid and flowing co-currently to said first liquid so that the dissolved impurities in said second liquid react with the film forming first liquid and dissolve therein, allowing the two liquids to flow downward to a separator and collecting the pure second liquid and if desires, recycling said first liquid.
