LINSON OIL // Since 2004
Gas-Liquid Separator for Process Gas & Production Streams
Custom horizontal and vertical gas-liquid separators configured around gas flow, liquid loading, pressure, temperature, fluid properties, required outlet condition, corrosion considerations, and site constraints.

01 // Separation Duty
What a Gas-Liquid Separator Removes
Process gas may carry free liquid, condensate and entrained droplets. A properly configured separator is used to remove bulk liquid and reduce liquid carryover before downstream compression, metering, treatment, dehydration or other gas-processing equipment.
- 01 Upstream protection: supports liquid removal before compressors, filters, control valves, meters, and gas-treatment equipment.
- 02 Production handling: separates liquid from wellhead, gathering, test, and production gas streams.
- 03 Gas treatment front end: reduces liquid loading before dehydration, sweetening, recovery, or fuel-gas systems.
Typical Gas Stream Treatment Path
Incoming
Wet Gas Stream
Gas with free liquid, condensate, entrained droplets and possible solids.
Separation
Gas-Liquid Separator
Vessel geometry, internals, liquid collection, demisting, level control and drains are configured to the process duty.
Gas Outlet
Liquid Outlet
02 // Process Principle
How Gas-Liquid Separation Works
The equipment arrangement is selected for actual operating conditions, with each stage contributing to gas cleaning and stable liquid handling.
Inlet Momentum Reduction
The inlet device slows, redirects, or distributes the incoming stream to reduce damaging velocity and initiate primary separation.
Bulk Liquid Separation
Larger liquid masses disengage from gas and fall into the vessel collection zone.
Gravity Settling
Residence time and vessel geometry allow smaller droplets to settle or coalesce under gravity.
Mist Removal
A mesh demister or other selected mist-elimination arrangement can reduce entrained liquid before the gas outlet.
Liquid Collection
Separated liquid accumulates in a dedicated sump or lower vessel section sized for operating variability.
Controlled Discharge
Level instruments, valves, drains, and project-specific control logic can be integrated for controlled liquid discharge.
03 // Procurement Terminology
Separator vs Knockout Drum vs Scrubber
Project terminology can vary by industry, client specification, process duty, and regional practice. LINSON OIL confirms the actual process scope instead of relying only on the equipment name.
| Project Term | Typical Project Context | Possible Configuration Direction | Data to Confirm |
|---|---|---|---|
| Gas-Liquid Separator | General process separation where gas contains free liquid and entrained droplets. | Horizontal or vertical vessel with inlet device, liquid section, mist eliminator, and controls. | Flow range, liquid loading, carryover target, pressure, temperature, fluid properties. |
| Knockout Drum | Often used where bulk liquid removal, slug handling, or upstream equipment protection is emphasized. | May prioritize liquid holdup, drainage, slug volume, or simple primary separation. | Slug size, liquid composition, drain philosophy, allowable gas velocity, plot space. |
| Gas Scrubber | Often referenced before compressors, burners, fuel gas systems, or treatment packages. | May place greater emphasis on mist removal, compact arrangement, or protection requirements for downstream equipment. | Downstream equipment limits, droplet size target, pressure drop allowance, turndown. |
04 // Vessel Orientation
Horizontal vs Vertical Gas-Liquid Separator
Orientation is selected from the process duty rather than from a fixed product rule. Gas capacity, liquid loading, surge or slug behavior, solids, plot space, maintenance access and transportation limits should be reviewed together.
Configuration A
Horizontal Separator
Often evaluated when
- Liquid holdup or surge volume is an important design input.
- A longer vessel footprint is acceptable within the site layout.
- Process review favors additional liquid disengagement or collection volume.
Configuration B
Vertical Separator
Often evaluated when
- A smaller plot footprint is preferred.
- Gas handling and liquid disengagement requirements suit a vertical arrangement.
- Bottom drainage or solids considerations influence vessel geometry.
Final orientation is subject to process calculations, project specifications, applicable design requirements and technical confirmation.
05 // Internals & Controls
Configure the Gas-Liquid Separation Train
Internal arrangements are selected according to flow pattern, liquid loading, required outlet condition, pressure drop considerations, controls and maintenance access.
Available by configuration
Inlet Device
An inlet arrangement can be used to control incoming momentum and begin bulk gas-liquid separation.
Flow Distribution / Baffle
Internal flow-control elements may be used where the selected vessel arrangement requires additional distribution or calming.
Mesh Demister
A wire-mesh or other selected mist-elimination arrangement can be considered to reduce entrained liquid in the gas outlet.
Liquid Collection
The lower vessel section or collection volume is developed around expected liquid loading and operating variability.
Level Control
Liquid-level instruments and outlet controls can be integrated according to the agreed operating philosophy.
Drain / Solids Provisions
Drain, blowdown or solids-handling provisions can be considered when required by the process and maintenance scope.
06 // Design Basis
Engineering Inputs for Quotation & Sizing
Complete process data enables a more accurate configuration, clearer technical scope, and faster commercial proposal. Incomplete data is acceptable at the early inquiry stage; our team can identify the critical gaps.
