DEVICE FOR SEPARATION OF WATER-GAS-OIL MIXTURE Russian patent published in 2003 - IPC

FIELD: oil producing industry, methods for transportation and separation of oil well products in gathering, treatment and transportation of oil. SUBSTANCE: device consists of pipeline with diameter d>2λ/2,61, and including inlet, middle and outlet parts. Middle part is filled with bundle of longitudinally oriented thin pipes. Outlet part has units of separation of fractions for gas, oil and water. Connected to n holes made on diametrically opposite generating lines of side surface of inlet pipe of pipeline with spacing 1≥1/αlge are branch pipes with wave guide flanges having length 1_p>λ/4 and diameter d_p>2λ/3,41 having dielectric radiotransparent sealing inserts length (I_p-d_p/2)≤1_d≤I_p with conical bore on side of flange with depth 0≤h<1_p, angle at vertex of 0<γ≤90^° and base diameter of 0≤d_v<d_p. Connected to waveguide flanges are n generators of ultrahigh frequency. Waveguide flanges of branch pipes located on diametrically opposite generating lines of side surface of inlet part of pipeline are turned relative to each other over branch pipes axis through angle of β=90 deg; where n is integer 1,2,3.. . ; λ is wave length of ultrahigh frequency generator; α is attenuation factor if electromagnetic wave in pipeline with water-gas-oil emulsion. EFFECT: higher treatment rate and quality of oil treatment. 2 dwg
