ABSTRACT:
The compound/curvilinear immiscible liquid separator has a separator section with an outer, elongated, cylindrical shell aligned vertically opening into an upper transition section and vapor dome at the top and a lower transition section and solid/heavy crude containment section at the bottom. A center column is disposed in the axial center of the separator section and a plurality of serially connected curved plates are disposed between the outer shell and center column to define an elongated curvilinear flow path having reverse flow pathways. An oil-water-gas mixture is introduced into the separator section under pressure past heating coils and through the curvilinear path, the lighter density oil entering and being removed from the top of the center column, and heavier sludge and brine collecting in the containment section. Gases bubble up through the center column and are removed from the vapor dome.
