FIELD: oil desalting technique which may be used in oil-fields for preparing of commercial oil, and for primary processing of oil.;SUBSTANCE: apparatus has housing of non-magnetic material provided with lower bottom and mounted on base equipped with receptacle incorporating permanent magnet disk. Within housing there is upper manifold formed as perforated cross-piece connected by welded joint to discharge branch pipe for desalted oil, and lower manifold adapted for feeding of basic oil and being similar to upper manifold. Both manifolds are made from non-magnetic material.;EFFECT: increased desalting efficiency and reduced consumption of power.;2 cl, 1 dwg
