Abstract: FIELD: applicable in a system of petroleum collection near objects consuming water for maintaining the seam pressure, and on petroleum preparation plants at considerable production process pressures. SUBSTANCE: the plant represents two inclined pipes located one above the other interconnected by equally spaced cross-pieces. The damper of flow-fed from the system of collection of gas-liquid mixture represents a horizontal pipe. Provision is made for a crosspiece for separate supply of gas from the damper to the upper inclined pipeline, and petroleum and water directly pass over to the lower one. Supply of gas, petroleum and water from the damper to the inclined pipelines is accomplished at a certain distance from their upper ends. Discharge of petroleum and gas is effected from the upper ends of the inclined pipelines, and discharge of cleaned water - from the end of the lower pipeline. Water fed from the lower part of the flow damper to the lower inclined pipeline is directed downwards. Gas bubbles and petroleum drops float up, pass over through the crosspieces to the upper inclined pipeline and go out to the petroleum and gas discharge line. Water cleared of free gas and petroleum is directed to the consumer. The petroleum and gas phases fed from the damper to the lower and upper inclined pipes rise to the upper ends of the pipelines and pass over to the discharge line. EFFECT: enhanced efficiency. 4 dwg

Abstract: FIELD: refining of petroleum products. SUBSTANCE: method of refining of liquid petroleum products consists in their breakage into drops by way of continuous hydraulic atomization and subsequent thermal fractionation; the average size of drops does not exceed 0.30 mm, and the time interval between atomization and fractionation does not exceed 5 min. To increase the yield of white fractions distilled off under 200 C, petroleum is atomized by subjecting the liquid microvolumes to the effect of shearing stresses arising at intensive turbulization, and to increase the yield of fractions distilled off within a temperature range from 200 to 350 C, petroleum products are atomized under the action of compression stresses arising at an impact of liquid against an obstacle. The device used to accomplish the described method has a vessel for source liquid petroleum products, container with a heating appliance, pump and an injector with a slot or deflector atomizer, interconnected by pipes. For atomization of petroleum products under the action of shearing stresses use is made of the slot atomizer, having a cylindrical duct with a hemisphere in the upper outlet part intersected by an isosceles wedge; the upper rib of the wedge faces the liquid flow and at an intersection with the duct axis forms a right angle, and the relation between the length of the smaller axis formed at intersection of the hemisphere and wedge, ellipse and the duct diameter is within 0.2 to 0.6. For atomization under the action of compression stresses use is made of the deflector atomizer, having a cylindrical duct and inclined obstacle; the axis of duct symmetry and normal to the obstacle surface in the point of its intersection with the axis form an acute angle within 5 to 30 deg, and the relation between the distance from the duct edge to the obstacle and the duct diameter is within 0.7 to 3.5.
