Abstract
A method for separating a first liquid from a second liquid, with the one liquid not being soluble in the other, the first liquid being contained as droplets in the second one, and with the two liquids having different densities. In a first step the liquid mixture is conducted during a first time interval as a turbulent flow through installations, in particular through a filler body in a packing column or through a static mixer, for coalescing the droplets. In a second step the flow rate of the mixture is reduced during a second time interval to continue the coalescence, and, in a third step, the speed of the mixture flow is further reduced and directed opposite to or with the force of gravity so that larger descending or rising droplets can be collected and separated out. The smaller droplets are carried along further by the second liquid.
