WATER-DISCHARGE PLANT Russian patent published in 1997 - IPC

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
