INSTALLATION FOR SEPARATING GAS FROM LIQUID AND SOLID PHASES Russian patent published in 2009 - IPC B01D45/12 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas producing industry and is designed for implementation at development of oil deposits by means of gas or water-gas effect onto oil saturated reservoir with high reservoir pressure using natural gas of high pressure. The installation for separating gas from liquid and solid phases consists of a cylinder case, of semispherical cover and bottom, of an inlet sleeve of gas-liquid mixture of rectangular cross-section, of an outlet gas sleeve, of liquid phase drainage sleeve arranged below the side surface of the cylinder portion of the case and of a solid phase discharge sleeve installed in the semispherical bottom. The inlet sleeve of gas-liquid mixture is mounted tangentially to the internal cylinder surface of the case, while its rectangular cross section is equipped with a spring loaded plate designed to travel around vertical axis and to shut off the area of the sleeve cross section. The lower end of the outlet sleeve of gas is lowered below the inlet sleeve of gas-liquid mixture approximately to the middle of the cylinder part of the case and is equipped with a drop catcher filled with Rashig rings. The cylinder case, semispherical cover and bottom are made three-layered; also the external and internal layers are made out of steel, while the intermediate layer is made out of solidificated solution, for instance Portland cement or solidificated resins. Solifidicated solution is pumped into a space between metal layers via a technological sleeve installed in the external layer of the bottom till excess solution pours out through the technological sleeve installed in external layer of the cover of the installation. The technological sleeves are shut off after solidification of the solution.

EFFECT: facilitation of high operational pressure without considerable metal consumption and cost, also facilitation of high quality of separation at high static pressure inside installation regardless of variation of volume of gas passing through installation.
