Abstract:
Device for separating two non-mixable liquids with different specific gravities, which device contains a first filterless separation tank (2) working under atmospheric pressure, with an overflow (11, 12) for each of the liquids to be separated, a coalescence filter (3) whose inlet (14) is connected via a pipe (13) to the overflow (12) of the first separation tank (2) for the liquid with the highest specific gravity and a second filterless separation tank (4) which is connected to the outlet (19) of the coalescence filter (3), characterised in that the overflow (12) onto which the coalescence filter (3) is connected is situated higher than the inlet (14) of the coalescence filter (3) with a difference in height H1 which is such that the liquid mass in the pipe between the first separation tank (2) and the coalescence filter (3) provides for the necessary pressure to bridge the pressure drop in the coalescence filter (3) and the counterpressure of the liquid in the second separation tank (4).
