DEVICE FOR OIL DESALTING AND DEHYDRATION Russian patent published in 2017 - IPC C10G33/06 B01D17/04 

FIELD: oil and gas industry.

SUBSTANCE: device for oil desalting and dehydration comprises a tube with holes, a manifold with a reagent (water) feeding pipe branch, oil inlet chamber which is coaxial with the pipe and comprises cylindrical middle and inner tube flow splitters of treated oil which are fitted with nozzles and placed concentrically to the housing at calculated distances, which form the outer, middle and inner flows, wherein the inner splitter is made with outer and inner walls, between which there is an annular cavity for reagent (water), and before the flow splitters there are water collector rings for pre-turbulation of the treated oil at adjusted distance.

EFFECT: increased efficiency of oil desalting and dehydration and plant capacity due to intensification of mixing the treated oil with a reagent, turbulation and separation of all the oil flow volume into several concentric ones with the specified flow thicknesses.
