LINSON OIL // Natural Gas Processing Equipment

Molecular Sieve Gas Dehydration Unit for Natural Gas Treatment

Adsorption-based dehydration equipment and skid-mounted systems engineered around gas composition, flow, pressure, temperature, required outlet condition, utilities and project standards.

LINSON OIL supplies molecular sieve dehydration equipment and integrated skid systems for natural gas treatment duties where water removal, reliable sequencing, documentation and project-specific engineering are required.

What It Does

Water Removal for Defined Gas Processing Duties.

A molecular sieve gas dehydration unit removes water vapor from a natural gas stream to support downstream processing, transport, product handling or other project requirements. The adsorbent, adsorption arrangement and regeneration philosophy are engineered around the actual operating duty rather than assumed as a standard package.

Protect

Support downstream equipment and processing requirements.

Condition

Treat gas according to the defined water specification and project scope.

Integrate

Coordinate dehydration with upstream and downstream process interfaces.

How It Works

A Process Arrangement Built Around the Actual Duty.

The process arrangement is developed from feed conditions, required downstream condition, utility basis, controls philosophy and project standards. Upstream preconditioning, regeneration equipment and return-to-service sequencing are included as required by the process design.

Adsorption & Regeneration Philosophy

More Than Gas-Liquid Separation.

Molecular sieve dehydration uses adsorption to remove water from the gas stream. Once the adsorbent approaches its working limit, it requires a regeneration, cooling and return-to-service sequence. The sequence, switching arrangement and degree of automation depend on the process design and project scope.

  • Adsorption removes water from the defined gas stream.
  • Saturated adsorbent requires regeneration before return to operating service.
  • Switching and sequence control can be automated depending on project scope.

Supply Configuration

Standalone Unit or Integrated Skid.

Option 01

Dehydration Equipment Scope

Equipment can be supplied for integration into a wider customer or EPC package, with scope and interfaces defined during technical clarification.

  • + Pressure equipment and selected process components
  • + Engineering documents according to agreed scope
  • + Defined fabrication, inspection and delivery interfaces

Option 02

Integrated Molecular Sieve Dehydration Skid

A skid-integrated package can reduce site interface work by combining selected process equipment, piping, instruments, controls and structural support within an agreed delivery boundary.

  • + Adsorbers
  • + Regeneration equipment
  • + Piping
  • + Valves
  • + Instruments
  • + Controls
  • + Structural skid

Final configuration is determined by the process design. Not every project requires the same heater, cooler, separator or auxiliary equipment scope.

Technical FAQ

Questions Before You Specify.

How does molecular sieve dehydration work?
Molecular sieve dehydration uses an adsorbent to remove water vapor from the gas stream. The adsorbent is periodically regenerated and returned to service according to the selected process arrangement and operating sequence.
What gas data is needed for selection?
Key information includes gas composition, flow range, pressure, temperature, inlet water content, contaminants, required downstream condition, utilities, hazardous-area requirements, applicable standards and battery limits.
How many adsorbers are required?
Adsorber quantity and operating sequence are selected by project. The final arrangement depends on process conditions, regeneration philosophy, availability requirements and the agreed design basis.
Is regeneration automatic?
Switching and sequence control can be automated depending on project scope, control philosophy and the required degree of operator involvement.
Can the system be supplied as a complete skid?
Yes. Depending on the agreed scope, LINSON OIL can supply an integrated skid incorporating selected adsorbers, regeneration equipment, piping, valves, instruments, controls and structural support.
What outlet water condition can be achieved?
The achievable outlet condition depends on feed composition, pressure, temperature, adsorbent selection, cycle design and project requirements. It should be confirmed during process engineering.
