A process gas dryer should be selected using gas composition, outlet moisture basis and regeneration utilities, with the receiving site and upstream or downstream equipment included in the discussion. Compare the proposed configuration, stated assumptions and a realistic acceptance trial together. Ask each supplier to identify exclusions, maintenance responsibilities and unresolved application questions. Define OEM branding separately from ODM integration changes so an altered machine is assessed against the same documented production requirement.
Compare process gas dryer proposals around gas composition, outlet moisture basis and regeneration utilities. Define the process boundary, supporting equipment and acceptance evidence before choosing a configuration. Send the same application details to each bidder and include project-specific OEM or ODM requirements in the initial inquiry.

Specify the gas rather than a generic dryer size
Provide full gas composition, contaminants, inlet pressure and temperature, flow range and the required outlet moisture. State whether the requirement is a pressure dew point at operating conditions or another defined moisture basis. A standard compressed-air dryer must not be assumed compatible with an arbitrary process gas. Have the manufacturer and responsible process specialists review gas service, wetted materials and the intended application.
Explain how moisture affects the receiving process, such as freezing, corrosion or product quality. Include normal and abnormal inlet conditions. A dryer selected from one ideal gas condition can be inappropriate when the composition or incoming liquid load changes during the production cycle.
Match adsorption and regeneration to the gas duty
Ask how the proposed dryer removes water, regenerates its media and returns to service. Compare purge-gas use, heating or other regeneration utilities, cycle behavior and the destination of regeneration exhaust. The appropriate concept depends on gas availability and process conditions. A low outlet-moisture claim does not show whether the receiving plant can support the regeneration method or tolerate its consumption.
For continuous service, review changeover between operating stages and any effect on outlet pressure or moisture. Ask which conditions require the process to stop or divert gas. Keep the responsible control sequence distinct from a broad statement that a twin-vessel package operates continuously.
Keep each gas-specific reference bounded
No. The SILOXA ADTR reference is specifically a biomethane adsorption-drying example. Delair’s documentation illustrates broader engineered process-gas dryer scope. Neither reference establishes that one photographed package is suitable for hydrogen, oxygen, carbon dioxide or every other gas. Require an application-specific compatibility and performance response for the exact proposed equipment, including media, seals, valves and contamination limits.
Ask the bidder to identify which information comes from a standard module and which requires project engineering. Avoid selecting an adsorbent or material solely from a familiar chemical name. The responsible manufacturer should assess the complete service and the consequences of unexpected contaminants.
| Decision | Requirement to state | Evidence to request |
|---|---|---|
| Gas | Composition and contaminants | Application-specific compatibility review |
| Moisture | Required basis and operating pressure | Agreed measurement definition |
| Regeneration | Purge, heat, utilities and exhaust | Declared full-cycle consumption and sequence |
| Boundary | Separators, filters and monitoring | Process flow and responsibility diagram |
| Acceptance | Flow, gas and inlet variation | Qualified traceable drying-cycle test |
Allocate treatment boundaries and instruments
Itemize inlet liquid separation, filtration, adsorber vessels, regeneration equipment, after-filtration and moisture monitoring as applicable. Allocate gas isolation, venting and protective systems to the responsible designers for the destination and application. Show where samples are taken and how instruments are serviced. A dryer-skid photograph does not define the surrounding process protection or guarantee that all inlet contamination is handled.
Provide utilities, ambient conditions and maintenance access for replacing media and servicing valves. If the installation is enclosed or in a classified area, have qualified responsible parties define the design requirements. Keep responsibility for the gas plant and the dryer package explicit in the offer.
Verify moisture across the actual operating cycle
Agree a qualified application-specific test stating gas composition, inlet conditions, flow, pressure and outlet-moisture measurement basis. Observe the representative drying and regeneration sequence, including changes between stages where applicable. Record sampling and analyzer conditions. A reading at a convenient depressurized sample point cannot be treated as the operating-pressure dew point without the agreed measurement method and interpretation.
Define how deviations in test gas or inlet condition are addressed before acceptance. Retain instrument calibration and package configuration with the report. Ask who investigates a shortfall involving upstream liquids, gas composition, utilities or a regeneration control issue so corrective action has a clear ownership route.
Treat customized gas packages as engineered ODM
OEM labels and documents must retain pressure-equipment and component traceability. ODM work can change gas service, regeneration, controls, vessel arrangement or process interfaces. Require review by the responsible manufacturers and process specialists, with revised drawings and acceptance. A privately labeled enclosure does not transfer another package’s gas compatibility, regulatory documentation or performance evidence to a changed application.
Request approved media and valve service identifiers for the exact gas configuration. Keep restrictions and maintenance responsibilities in the handover. A later feed-gas change should trigger engineering review rather than an assumption that spare drying capacity covers an entirely different composition.

Frequently asked questions
What should I specify for a process gas dryer?
Provide full gas composition, contaminants, inlet pressure and temperature, flow range and the required outlet moisture. State whether the requirement is a pressure dew point at operating conditions or another defined moisture basis. A standard compressed-air dryer must not be assumed compatible with an arbitrary process gas. Have the manufacturer and responsible process specialists review gas service, wetted materials and the intended application.
How should regeneration be compared for a gas dryer?
Ask how the proposed dryer removes water, regenerates its media and returns to service. Compare purge-gas use, heating or other regeneration utilities, cycle behavior and the destination of regeneration exhaust. The appropriate concept depends on gas availability and process conditions. A low outlet-moisture claim does not show whether the receiving plant can support the regeneration method or tolerate its consumption.
Does a biomethane dryer reference establish suitability for other gases?
No. The SILOXA ADTR reference is specifically a biomethane adsorption-drying example. Delair's documentation illustrates broader engineered process-gas dryer scope. Neither reference establishes that one photographed package is suitable for hydrogen, oxygen, carbon dioxide or every other gas. Require an application-specific compatibility and performance response for the exact proposed equipment, including media, seals, valves and contamination limits.
What belongs around a process gas drying package?
Itemize inlet liquid separation, filtration, adsorber vessels, regeneration equipment, after-filtration and moisture monitoring as applicable. Allocate gas isolation, venting and protective systems to the responsible designers for the destination and application. Show where samples are taken and how instruments are serviced. A dryer-skid photograph does not define the surrounding process protection or guarantee that all inlet contamination is handled.
How should a process gas dryer be accepted?
Agree a qualified application-specific test stating gas composition, inlet conditions, flow, pressure and outlet-moisture measurement basis. Observe the representative drying and regeneration sequence, including changes between stages where applicable. Record sampling and analyzer conditions. A reading at a convenient depressurized sample point cannot be treated as the operating-pressure dew point without the agreed measurement method and interpretation.
Can a process gas dryer support OEM or ODM requirements?
OEM labels and documents must retain pressure-equipment and component traceability. ODM work can change gas service, regeneration, controls, vessel arrangement or process interfaces. Require review by the responsible manufacturers and process specialists, with revised drawings and acceptance. A privately labeled enclosure does not transfer another package's gas compatibility, regulatory documentation or performance evidence to a changed application.
