Separators
Separation Equipment Engineered for Tough Operating Conditions
Precision-built for multi-phase flow control, vapor management, and bulk liquid separation.
Petrosmith designs and fabricates a full line of ASME-certified separation equipment engineered to optimize production, protect downstream equipment, and improve process efficiency. Our separators are used to remove gas, oil, water, solids, and vapor from complex process streams, supporting Oil + Gas production, Industrial & Petrochemical Processing, HVAC + Refrigeration, Renewable Energy, and Water Treatment + Filtration operations.
Manufactured with Pressure Vessel Quality (PVQ) steel, high-performance internals, and industry-specific coatings, every unit is engineered to meet site conditions, flow rates, and safety specifications. From standard two-phase designs to high-volume slug catchers and vapor recovery towers, we deliver dependable separation solutions for high-pressure, high-temperature, and corrosive environments.
Our Separation Equipment Offerings
Two-Phase Separators
Offered in both horizontal and vertical configurations, these separators are designed to split gas from mixed liquid streams in upstream production and midstream gathering systems. Ideal for well pads, central facilities, compressor stations, and vapor-controlled tank batteries.
Three-Phase Separators
Offered in both horizontal and vertical configurations, these separators are engineered to separate gas, oil/condensate, and produced water with consistent interface control. Optimized for high liquid rates, heavy emulsions, and variable flow conditions.
Vapor Recovery Towers (VRTs)
Low-pressure towers used ahead of atmospheric storage tanks to remove flash gas and reduce VOC/methane emissions. Commonly paired with VRUs in oil & gas, LNG, refineries, chemical facilities, and renewable energy applications.
Slug Catchers
Vessel-type and pipe-type slug catchers built for high-volume surges in multiphase pipelines. Protects downstream separators, compressors, and process equipment.
Free Water Knockouts (FWKO)
Bulk free-water removal vessels used to reduce water content prior to heater treaters, storage, or produced water treatment systems.
Induced Gas Flotation Vessels
De-oiling units for produced water and industrial wastewater. Uses fine gas bubbles and flotation to remove suspended oil droplets and solids.
