Biogas upgrading is the treatment of raw biogas to adjust its composition and quality for an intended use. The process may involve separating carbon dioxide and treating moisture or other contaminants, depending on the feed gas and required output.

Gaskon’s listed technologies are Pressure Swing Adsorption (PSA), Vacuum Swing Adsorption (VSA/VPSA), Pressurized Water Scrubbing (PWS), amine scrubbing, membrane separation, and cryogenic separation.

The choice depends on feed-gas composition, flow rate, required product-gas quality, intended use, utilities, and site conditions. A project assessment should compare those requirements against the technologies being considered.

Useful information includes the biogas source, composition, flow and variation, intended use of the upgraded gas, target gas quality, operating schedule, utilities, and site location.

It may. The required pretreatment depends on the feed gas and the selected upgrading process. Moisture, hydrogen sulfide, siloxanes, and other components may need to be addressed for the particular application.

PSA uses adsorbent material and pressure changes to separate gas components. Membrane systems use selective permeation through membrane material. The appropriate choice depends on project conditions and required output.

In water scrubbing, biogas contacts water under controlled conditions. Components that dissolve more readily into water transfer from the gas into the liquid. System design depends on the gas composition, process conditions, and water-management requirements.

Amine scrubbing uses a chemical solvent to absorb selected components from a gas stream. The solvent is then treated for reuse as part of the process. Feed-gas composition, solvent handling, and utility requirements should be reviewed during project planning.

Cryogenic separation uses low-temperature processing to separate gas components. Its suitability depends on the feed gas, product requirements, process conditions, utilities, and project scope.

Send the available feed-gas analysis, expected flow rate, target product-gas quality, intended use, site location, utilities, and project timeline. If you do not have a gas analysis yet, mention that in your enquiry.

An oxygen generator separates oxygen from ambient air to provide an on-site oxygen supply. The system and its output must be selected for the intended application and facility requirements.

They serve different applications and may have different quality, regulatory, monitoring, and installation requirements. Medical oxygen systems must meet the applicable requirements for their intended healthcare use; confirm these before selecting equipment.

Sizing starts with expected average and peak demand, required oxygen quality and pressure, operating schedule, and facility plans. For healthcare applications, demand assessment and system planning should account for the wider oxygen supply system, not just the generator.

Provide the intended application, average and peak flow, required quality and pressure, operating hours, site location, utilities, and any applicable standards or approvals.

System duty and operating schedule depend on the selected model and installation. Confirm the generator’s rated operating conditions, maintenance schedule, and any required backup supply with the supplier.

PSA oxygen plants typically include air-treatment and electrical components. Site power, air-system arrangement, space, ventilation, and connection requirements should be reviewed for the specific system.

Maintenance depends on the model and operating conditions. Follow the manufacturer’s schedule for inspection, air-treatment components, analyzers, and other system parts. Medical oxygen plants also require trained operators and planned maintenance.

Healthcare facilities should plan for continuity of oxygen supply, including what happens during power interruption, maintenance, or equipment downtime. The backup arrangement should be determined by facility needs and applicable requirements.

Oxygen may be distributed through a facility system or, with suitable additional equipment, compressed for cylinder filling. The required configuration depends on the application and should be specified during project planning.

Include whether the application is industrial or medical, the required flow and pressure, target oxygen quality, operating schedule, facility location, utility availability, and any relevant standards or project documents.

Gaskon lists pure hydrogen purification and drying systems, and ammonia crackers that produce hydrogen through ammonia dissociation. Confirm current models and scope directly with the company.

A hydrogen purification system treats an existing hydrogen-rich gas stream to reduce selected impurities and help meet a required outlet specification. The process depends on the inlet composition and target quality.

Hydrogen streams can contain moisture, depending on their source and process. Drying removes water vapour when the downstream application or equipment requires a drier gas.

Provide the inlet gas composition, flow rate, pressure, target outlet quality, moisture requirement, downstream application, and operating schedule.

An ammonia cracker dissociates ammonia (NH₃) into a hydrogen-containing gas stream. Depending on the intended use, additional separation or purification may be needed to reach the required hydrogen quality.

Not necessarily. Cracking produces a gas mixture, so the project may require downstream separation or purification. The required process depends on the application and hydrogen specification.

Sizing depends on the required hydrogen output, operating hours, ammonia supply, target product quality, and downstream demand. Share the expected hydrogen use and process conditions for an initial assessment.

The project review should establish the required utilities, feedstock and gas connections, ventilation and safety provisions, installation space, and integration with downstream equipment. Requirements depend on the system configuration and local regulations.

Integration may be possible, but it depends on inlet conditions, piping and pressure requirements, controls, available space, and the downstream process. Provide relevant process drawings or specifications when requesting a review.

Include the system type, intended application, hydrogen demand, inlet gas details if available, required outlet quality, pressure, utilities, site location, and expected project schedule.

The range includes compressed air dryers, exo gas generators, endo gas generators, N₂ + methanol systems, and gas purifiers.

Start with the required pressure dew point, airflow, operating pressure, inlet conditions, ambient temperature, and the lowest temperature the air system may experience. Dryer selection depends on the air-quality needs of the application.

Pressure dew point is the temperature at which moisture in compressed air begins to condense at the system’s operating pressure. It helps define how dry the air needs to be for an application.

They use different drying methods and serve different pressure-dew-point requirements. A refrigerated dryer is commonly used for general industrial air needs; a desiccant dryer is considered when a lower dew point is required. Selection should follow the process specification.

An exo gas generator produces a process gas through a controlled exothermic reaction. The suitable system depends on the required gas atmosphere, process equipment, operating conditions, and application.

An endo gas generator produces a process gas through a controlled endothermic reaction. System selection depends on the application, feed requirements, target gas composition, and downstream process conditions.

It combines nitrogen and methanol as part of a process-gas system. The exact configuration and suitability depend on the process, required gas atmosphere, operating conditions, and equipment being served.

A gas purifier is designed to reduce specified contaminants from a gas stream. The contaminants it can address depend on the purifier technology and configuration, so the inlet composition and required outlet specification should be provided.

Potential integration depends on the existing process, operating pressure, flow, controls, utilities, and connection points. A review of the plant requirements and equipment details is needed before confirming compatibility.

Specify the product, application, flow or capacity, inlet and outlet conditions, required air or gas quality, operating schedule, site location, utilities, and any relevant process drawings.

An on-site nitrogen generator produces nitrogen from compressed air using a separation process. PSA and membrane are two common approaches; the choice depends on the application and required output.

PSA uses adsorbent material and pressure cycling to separate gases. Membrane systems use selective permeation through membrane fibres. The suitable method depends on purity, flow, pressure, and operating requirements.

Purity depends on the technology, model, flow, inlet-air conditions, and system settings. Gaskon’s product information lists PSA systems from 95% to 99.999% and membrane systems from 95% to 99.5%; confirm the available range for the specific model and required flow before specifying it.

Sizing should account for average and peak nitrogen demand, required purity and pressure, operating hours, and demand variation. Include current and planned process requirements when discussing capacity.

Nitrogen generators that separate nitrogen from compressed air need a suitable source of compressed air. Whether a compressor is included or supplied separately depends on the project configuration.

Moisture, oil, hydrocarbons, or particles in the feed air can affect generator performance and gas purity. The required filtration and drying should follow the selected model’s specifications.

A generator may be configured for the process’s operating pattern, but continuous supply depends on correct sizing, feed-air availability, storage, utilities, and maintenance. Confirm the duty requirements for the selected system.

Storage needs depend on demand peaks, flow variation, required pressure stability, and the generator configuration. The system should be assessed as a complete supply arrangement, including storage and distribution.

Maintenance depends on the technology and model. It may include checks of filters, air-treatment components, operating pressure, flow, and system performance. Follow the supplier’s maintenance schedule and use qualified personnel where required.

Share the application, nitrogen flow, required purity and pressure, operating schedule, feed-air availability, site location, and whether you need a compressor, dryer, storage tank, or other associated equipment.
