Abstract:
A method of mixing and separating two immiscible liquids of different densities, the method comprising:feeding a mixing with said two liquids so as to fill the mixer up to a given level;stirring within said mixer so as to produce a dispersion of said two liquids;conveying said dispersion to a decanting apparatus; this being done under condition where said dispersion pre-separates into two fractions, separated by a phase boundary, each enriched with a respective one of said two liquids; andseparately recovering and separately treating said two pre-separated fractions, independently from each other, within said decanting apparatus,so as to obtain four separate flows, a first main one and a first secondary one from one of said two pre-separated fractions and a second main one and a second secondary one from the other of said two pre-separated fractions.
