Equipment

Phase Separation

SPEC engineers and fabricates separators that split produced fluids into gas, oil and water at wellhead and inlet conditions, using momentum, gravity settling and coalescing.

Equipment Range

Vertical or horizontal, two or three phase. Selection follows the gas to liquid ratio, density and viscosity differences, operating conditions, particulate size, slug volumes and the presence of H₂S or CO₂.

Capabilities

Design and Fabrication Features

Inlet momentum breakers

Diverter plate, half pipe or cyclonic inlet devices reducing inlet velocity as the first separation stage.

Mist extractors

Removing liquid still carried in the gas stream before the outlet nozzle.

Retention time by duty

Retention time depends on fluid properties, duty and required outlet quality.

Skid-mounted units

Vessel, piping and instrumentation on a common skid for straightforward installation.

Sand jetting and heating coils

Available where solids accumulation or fluid temperature require it.

Sour service materials

Materials selected to NACE requirements where H₂S is present in the stream.

Wave breakers

Internal baffling for floating and offshore installations where motion affects the liquid level.

Interface level control

Gas and liquid control with interface control on three-phase duty, plus pressure, temperature and safety devices.

Configured to the duty

Configured around process requirements, operating conditions and project scope, including separators built to the client's own specification.

Applications

Where This Equipment Is Used

Wellhead

First-stage separation close to the well, where slug volumes and particulate size drive the vessel sizing. Six 20,000 BOPD sour crude separation trains were fabricated and shop-tested for the Tawke early production facility in Iraq.
