摘要：NOVELTY - A mixed oil and water separating method involves mixing synthetic water containing light oil and containing traces of hydrocarbons, feeding into the trace gas oil hydrocarbon oil preliminary separator head to the left, feeding sewage to separator to the right of preliminary head, preliminary separation of oil and water. Components are entered into preliminary separator for liquid-gas separation in T-type liquid-gas separator, followed by passing mixture into the depth of the dewatering device having comprising hydrophilic fibers and lipophilic fibers with dewatered fiber module combination. USE - Method for separating mixed oil and water. ADVANTAGE - The method enables quickly and efficiently achieving oil dehydration and sewage degreasing and maximizing oil recovery. DETAILED DESCRIPTION - A mixed oil and water separating method involves mixing 0.5-6% synthetic water containing light oil and containing traces of hydrocarbons, 0.01-2.8% low gas, feeding into the trace gas oil hydrocarbon oil preliminary separator head to the left, feeding 0.05-0.5% sewage to the oil-water separator to the right of the preliminary head, preliminary separation of the oil and water at operating pressure of 0.3-4.5 MPa, a temperature of 20-60 degrees C. Components are entered into first preliminary separator for liquid-gas separation in T-type liquid-gas separator, separated gas from the top of the low water discharge preliminary separator at aqueous light oil flow rate of 0.005-0.02m/s flow from the left head of the oil-water separator to the right initially, followed by passing mixture into the depth of the dewatering device having comprising hydrophilic fibers and lipophilic fibers with dewatered fiber module combination, isolated particle size of greater than 30 mu m droplets, continue to the right bulkhead discharged into a deep dehydrator, removing a particle size of 3-30 mu m droplets in degasifier, in which case the resulting gas oil containing less than 0.02%, oily water separator of the initial water from the head to the right side left flow, second CPI water separation module, lipophilic module for rapid coarse degreasing, isolated particle size greater than of 25 mu m droplets, after the separation of sewage in the oil of 0.03-0.6% and continues to flow to the left the right of the separator, the light oil mixing baffle from the upper left of the separator and the separated discharged into a deep degreasing, removal of particle size in the depth demister for droplets of 1-25 mu m and oil content of the effluent of less than 0.01%.
