PROCESS
⸺ Function
Oil and gas phase separators separate oil, gas, and water phases encountered in production streams, removing liquid droplets, gas bubbles, and solids to obtain clean, separated streams.
⸺ Separation Principles
Separation relies on gravity-based settling, centrifugal force, and coalescence. Design and internal components facilitate efficient separation by maximizing contact and residence time.
⸺ Types of Separators
Vertical and horizontal separators are common. Vertical separators are suitable for high pressure gas and low-to- medium liquid loadings, while horizontal separators are ideal for low-pressure gas and high liquid loadings. Two-phase separators separate gas and liquid, while three-phase separators separate oil, gas, and water.
⸺ Design Considerations
Factors such as flow rates, pressure, temperature, fluid properties, and desired separation efficiency influence separator design. Vessel size, internals (e.g., mist extractors, coalescers), and outlet configurations are chosen for optimal performance.
⸺ Operating Parameters
Oil and gas phase separators operate under specific pressure and temperature conditions. Pressure drops, retention time, and appropriate control devices are critical for efficient operation.
