Abstract
A multistage separator for oilfield emulsions is disclosed. The separator utilizes a mechanical inclined plate separator constructed of electrically nonconductive materials disposed downstream of an electrostatic separation section. Electrostatic charges imparted to the flowing emulsion by the electrostatic section migrate to the mechanical portion and establish a surface charge on the inclined plates thereof. This surface charge results in enhanced coalescence of the aqueous and nonaqueous dispersions present in the emulsion.
