Inline Separator Skid

Compact, in-piping-run separation packages that pull free liquids, condensate, and slugs out of gas, steam, and compressed air lines — protecting downstream compressors, meters, and instrumentation without the footprint of a full separator vessel.

Overview

Liquid removal built into the pipe run, not bolted beside it

An inline separator skid mounts directly in a gas, steam, or compressed air line and strips out entrained liquid as the stream passes through — using vane packs, mesh pads, or cyclonic elements instead of the large gravity-settling volume a conventional separator vessel needs. Properly sized, an inline unit can remove as much as 99% of built-up condensation and free liquid through targeted, high-efficiency separation at the point the flow already has to pass.

Because entrained liquid is also the root cause of water hammer — the pressure surge that follows an abrupt change in flow direction or momentum — and a common driver of corrosion in downstream valves and piping, an inline separator protects both equipment integrity and process uptime with a fraction of the installed footprint of a knockout drum.

  • Vane-pack, mesh-pad (demister), or cyclonic separation elements
  • Sized against application-specific flow rate at a given pressure (psig), with model-specific correction factors applied
  • Corrosion-resistant materials for sour, saline, and marine-exposed service
  • Skid-mounted for straightforward installation into an existing pipe run

How It Works

From wet stream to protected downstream equipment

Every inline separator follows the same in-line separation path, sized to the specific flow and pressure it will see.

1

Flow & Pressure Rating

Application flow rate is matched against the unit's rated capacity at the line's operating pressure (psig), with the model's correction factor applied.

2

Inlet Momentum Break

An inlet diverter or momentum-break element slows and redirects the incoming stream, knocking out the coarsest liquid droplets first.

3

Coalescing & Capture

Vane packs, mesh pads, or cyclonic elements coalesce fine droplets and capture them out of the gas or vapor stream.

4

Liquid Drainage

Captured liquid drains to a collection sump or outlet, away from the main flow path, with automatic or manual drain control.

5

Dry Gas / Steam Discharge

The now-dry gas, steam, or compressed air stream continues downstream to compressors, meters, or process equipment, protected from carryover.

Separation Element Types

Matched to droplet size and service

VP

Vane-Pack Separator

Angled vane elements force the flow through repeated direction changes, throwing out liquid by inertia — low pressure drop, good for higher liquid loading.

MP

Mesh-Pad (Demister)

A knitted wire or fiber mesh pad coalesces fine mist and aerosol droplets that would otherwise pass through — the standard choice for polishing duty.

CY

Cyclonic Separator

Swirl-inducing internals spin the stream so centrifugal force throws liquid to the wall — compact and effective across a wide flow range with minimal moving parts.

Core Equipment

What's inside the package

Every Inline Separator Skid is built around the same proven separation and drainage train.

01

Inlet Diverter

Redirects and slows incoming flow, knocking out the coarsest liquid before it reaches the separation element.

02

Vane, Mesh, or Cyclonic Element

The primary separation internal, selected against droplet size distribution and allowable pressure drop.

03

Liquid Collection Sump

Captures separated liquid away from the main gas or steam flow path for controlled drainage.

04

Automatic & Manual Drain Valves

Level-controlled or manually operated drains removing collected liquid without interrupting flow.

05

Pressure Relief & Safety Devices

Code-rated relief protecting the skid and connected piping from overpressure events.

06

Level & Differential Pressure Instrumentation

Monitors liquid level and element loading, signaling when drainage or element service is required.
