Gas Liquid/Liquid-Liquid Separator Separation Type Pressure Vessel

Product Attributes
 

Our Gas Liquid / Liquid-Liquid Separator (Separation Type Pressure Vessel) is a custom-engineered, code-compliant pressure vessel designed for efficient phase separation in oil & gas, petrochemical, chemical, and refining processes. Manufactured in strict adherence to ASME Boiler & Pressure Vessel Code (Section VIII, Div. 1), GB/T 150, and other global pressure vessel standards, this separator combines robust structural integrity with advanced separation technology to reliably remove entrained liquids from gas streams or split immiscible liquid phases, ensuring downstream process stability, equipment protection, and product quality.

Core Design & Construction Features

Horizontal / Vertical Configuration Options

Available in both horizontal and vertical orientations to suit site layout, flow rate, and separation efficiency requirements:

Horizontal Separators: Ideal for high flow rates and large liquid hold-up volumes, featuring a long cylindrical shell with elliptical heads and saddle-type supports for stable installation. The extended horizontal path promotes gravity settling and uniform phase distribution.
Vertical Separators: Preferred for space-constrained installations and applications requiring compact liquid/gas separation, with skirt or leg supports and optimized inlet/ outlet nozzle placement to enhance gravitational separation.

Code-Compliant Pressure Vessel Engineering

Every unit is fully certified to ASME (U Stamp), GB/T 150, and regional standards (e.g., PED, CE) as required. Key engineering features include:

Design pressures ranging from 0.1 MPa to 42 MPa (customizable for high-pressure wellhead applications)
Design temperatures from -46°C to 450°C, tailored to process fluid properties
Full non-destructive testing (NDT) of welds (RT, UT, MT, PT) to ensure leak-tight performance and long-term operational safety
Stress analysis and fatigue life evaluation for cyclic service conditions

Corrosion-Resistant Material Selection

A wide range of materials is available to resist corrosive process fluids:

Carbon steel (Q245R, Q345R, A516 Gr.70) with internal coatings (epoxy, rubber, or fusion-bonded epoxy) for cost-effective general service
Stainless steel (304, 316L, 2205 duplex) for acidic, high-salinity, or high-temperature fluids
Clad plates (stainless steel / nickel alloy clad on carbon steel) to balance corrosion resistance and structural strength
High-nickel alloys (Inconel, Hastelloy) for extreme corrosive environments (e.g., sour gas, chloride-rich streams)

Advanced Internal Separation Components

Customizable internal internals are engineered to maximize separation efficiency for specific phase combinations:

Inlet Distributors: Reduce fluid velocity and distribute flow evenly across the vessel cross-section to prevent re-entrainment.
Demister Pads / Mist Eliminators: Remove fine liquid droplets (down to 5-10 μm) from gas streams using woven wire mesh, vane packs, or centrifugal elements.
Baffles & Weirs: Promote gravity settling of liquid phases and prevent short-circuiting, with adjustable weirs to optimize interface control for liquid-liquid separation.
Coalescing Elements: Enhance droplet coalescence in liquid-liquid systems, improving the separation of immiscible phases (e.g., oil-water, solvent-water).
Liquid Hold-Up Sections: Provide sufficient residence time for phase separation, with level control interfaces to maintain stable operation.

Precision Fluid Handling & Instrumentation

Strategically placed nozzles and instrumentation ports enable full process monitoring and control:

Process inlet/outlet nozzles for gas, liquid, and mixed-phase streams
Liquid drain and vent connections for commissioning, maintenance, and emergency discharge
Instrumentation ports for pressure gauges, temperature transmitters, level transmitters (capacitance, radar, or ultrasonic), and interface level sensors
Safety relief valve connections to protect against overpressure conditions, in compliance with ASME and local safety codes

Key Applications

Our separation-type pressure vessels are deployed across critical industrial processes where reliable phase separation is essential:

Oil & Gas Production: Wellhead separators, test separators, and production separators to split crude oil, natural gas, and produced water, protecting downstream pipelines and processing equipment.
Refining & Petrochemicals: Gas-liquid separation in distillation columns, hydrocrackers, and reformers, as well as liquid-liquid separation for solvent recovery and product purification.
Chemical Processing: Separation of reaction products, solvent recovery, and removal of entrained liquids from process gas streams to ensure product purity and protect catalysts.
Power Generation: Removal of moisture and liquid contaminants from steam and natural gas streams to protect turbines, boilers, and heat exchangers from corrosion and erosion.
Environmental & Water Treatment: Oil-water separators for industrial wastewater treatment, removing hydrocarbon contaminants to meet regulatory discharge standards.
LNG & Gas Processing: Natural gas dehydration and liquid recovery, separating natural gas liquids (NGLs) from methane to produce pipeline-quality gas.
