Gas Processing & Conditioning Systems
Molecular Sieve Gas Dehydration Unit
LINSON OIL supplies project-configured molecular-sieve gas dehydration units for natural-gas treatment. The dryer vessels, regeneration system, switching arrangement, piping, instruments and controls are developed from the gas composition, water content, operating conditions, required downstream gas condition and project specification.

Package Engineering
Dryer vessels, regeneration equipment, switching valves, piping, instruments and controls can be configured as an integrated project package.
Working Principle
A controlled adsorption and regeneration cycle.
Molecular-sieve dehydration uses a solid adsorbent bed to remove water from the gas stream. Dryer vessels operate through adsorption and regeneration stages, with the vessel arrangement, switching sequence, regeneration method and safeguards defined by the actual process basis and project requirements.
Inlet Conditioning
The incoming gas is evaluated with upstream separation, filtration or coalescing requirements to help protect the adsorbent and downstream equipment.
Adsorption Duty
Gas flows through the online dryer, where the selected adsorbent captures moisture according to the defined operating cycle and dehydration objective.
Regeneration Duty
The saturated bed is regenerated through a project-selected heating, cooling and purge arrangement before returning to standby service.
Sequencing & Changeover
Project-defined control logic coordinates switching, permissives, alarms and operating states for the selected vessel arrangement and operating philosophy.
Applications
Built for gas streams that require dependable moisture control.
The final process arrangement is reviewed against the gas source, impurity profile, downstream destination, operating environment and project execution scope.
Natural Gas Processing
Dehydration packages for gas conditioning before transport, further treatment, compression, metering or downstream process units.
Associated Gas Recovery
Gas dehydration as part of associated-gas recovery, conditioning, stabilization, NGL or integrated field processing schemes.
LNG-Related Feed Treatment
Molecular-sieve dehydration may form part of LNG-related gas treatment where the selected process scheme and downstream specification require this dehydration route.
Wellhead and Field Gas Facilities
Skid-mounted or integrated equipment for remote and field-based installations, subject to site layout, lifting, transport and utility conditions.
Main Systems & Configuration
One dehydration package, coordinated as a complete operating system.
A
Dryer Vessel System
Dryer-vessel quantity, internal arrangement, adsorbent support/distribution, access, material selection and vessel details are reviewed against the process and maintenance basis.
B
Regeneration System
Regeneration gas routing, heating and cooling duties, purge handling and related piping are configured around the selected regeneration philosophy and available utilities.
C
Valve & Piping System
Manual, automated and safeguarding valves, manifold piping, drains, vents, bypasses, supports and connection interfaces are defined within the approved scope of supply.
D
Control & Instrument System
PLC or project-specified control architecture, field instruments, local panels, alarms, interlocks, sequence logic and remote interfaces can be aligned with the site control philosophy.
Engineering Inputs
A stronger technical basis creates a clearer package scope.
When information is incomplete, our engineering team can help identify the questions needed for technical clarification before a formal package configuration is finalized.
