Nitrogen Generator (PSA)

medium 82 models total

A PSA nitrogen generator makes inert gas by separating air rather than burning fuel, which gives a cleaner, sulphur-free gas that chemical and gas carriers need where combustion-type inert gas would contaminate the cargo.

What sets PSA nitrogen generation apart

Conventional inert gas plants burn fuel oil and scrub the flue gas down to a low-oxygen mixture that still carries traces of sulphur oxides and soot. A Pressure Swing Adsorption nitrogen generator instead compresses ordinary air and pushes it through beds of carbon molecular sieve that adsorb oxygen preferentially, leaving a nitrogen-rich stream behind. There is no combustion, no flue gas chemistry to manage, and no fuel consumption tied to the inerting duty -- which is why chemical tankers and gas carriers favour it over flue-gas IG for cargoes that cannot tolerate combustion by-products.

Nitrogen generator (PSA) flow — Flow through a pressure-swing adsorption nitrogen generator: compressed air to an air receiver, alternating carbon molecular sieve towers switched by valves, oxygen-rich gas vented, and nitrogen collected in a buffer receiver for the inert gas main.

Main components

Air compressor and pre-treatment

Feeds dry, oil-free compressed air to the sieve beds; any moisture or oil carryover shortens sieve life sharply.

Carbon molecular sieve beds

Two or more vessels operating in alternating adsorption and regeneration cycles, so the plant delivers a continuous nitrogen stream while one bed vents captured oxygen and regenerates under reduced pressure.

Purity and flow control

An oxygen analyser on the product stream feeding a control valve that adjusts flow or diverts off-spec gas back to atmosphere until purity recovers after start-up.

Selection criteria

Required purity -- cargo tank blanketing often accepts 95 to 97.5 percent nitrogen, while some chemical grades demand higher purity and lower flow.
Flow rate matched to the largest single tank's filling or purging rate, since undersized plants cannot keep pace during fast discharge.
Sieve bed capacity and expected feed air quality, since ambient humidity and temperature both affect achievable purity.

Regulations and class

IACS UR and class rules for inert gas systems apply to PSA plants in the same way as combustion-type IG, covering oxygen content monitoring, alarm setpoints and backup arrangements. IMO's IGC Code addresses inerting requirements for gas carriers where nitrogen systems are common, and class surveys check the oxygen analyser calibration and the plant's ability to maintain the required tank atmosphere continuously through the voyage.

Typical faults

Sieve bed contamination from oil carryover in the feed air, which drops nitrogen purity gradually rather than all at once and can go unnoticed without trend logging.
Oxygen analyser drift, giving a false purity reading that either wastes nitrogen through unnecessary venting or, worse, allows an off-spec gas into the tank.
Regeneration valve wear causing incomplete bed switching, which shows up as a slow purity decline under high demand.
Undersized product buffer causing purity dips during rapid demand swings at the start of tank purging.

What to look for in a supplier

Sieve bed replacement intervals and cost stated up front, since this is the main recurring expense of the system.
Documented purity and flow performance across the ambient temperature and humidity range the vessel actually trades in.
Oxygen analyser type and calibration schedule compatible with the ship's existing spares and calibration gas stock.

Nitrogen purity on paper is measured at the analyser, not at the tank -- long, poorly purged distribution lines can let oxygen back-diffuse into the blanket gas well before it reaches the far tank, so check the actual tank atmosphere, not just the generator's output reading.

Area: Oxygen analyser sample line blockage due to carbon deposits
Check: Periodic test & cleaning of inert gas sample line to O₂ analyser (critical service position). Analyser itself: 2-point calibration (Zero-Gas N₂ 0%, Span-Gas known O₂ concentration) before operation. Calibration accuracy per manufacturer. Alarm setting: >8% O₂ volume.
Area: Deck Water Seal Wasserniveau & Funktionsprüfung
Check: Check water supply (min. 2 separate pumps required). Visual inspection water level (equipped with low-level alarm). Inspection PMS interval per manufacturer; special attention during IG system shutdown. Check for blockage/corrosion at openings.
Area: Pressure/Vacuum Breaker (P/V-Breaker) Druckeinstellung & Flammschutz
Check: Check flame screens/meshes (replacement per PMS plan). Calibration for required pressure values + test at operating pressure. Liquid-filled breakers: check fluid type & level; check anti-freeze additive in case of frost risk. Labelling with opening pressures & fluid type/concentration + min. operating temperature.
Area: Rückschlagventil (Non-Return Valve / Check Valve) Freigang & Ventilsitz
Check: Ventil zur Inspection öffnen. Prüfung auf Korrosion, Ventilsitz-Zustand, freie Ventilbewegung über volle Hublänge. Betriebsprobe im Service durchführen. Mindestens zwei Rückschlagvorrichtungen erforderlich (Deck Seal + Isolierventil). Kritisch für Hydrokarbon-Rückfluss-Verhinderung in Maschinenraum.
Area: Brennkammer-Zustand & Lagerzustand Flue-Gas-Rückzirkulations-Ventile
Check: Access to combustion chamber via hinged front (tool-free accessible — check for wear). Flue gas & recirculation valves regularly stroked (stroke test) when system out of service — ensure free operation over full stroke range. Inspection frequency per operating frequency.

Type

psa_n2

Purity pct

99.5

Common Failures & Inspection Points

Fouling, scaling or blocked spray paths reduce treatment effectiveness and cause abnormal pressure drop or emissions readings
Pump, blower or fan faults cause low circulation or gas flow and system shutdown
Analyzer or sensor contamination causes incorrect gas-quality, emissions or oxygen readings
Seal, valve or piping leakage causes liquid or gas leakage and unstable process pressure
Control, dosing or interlock faults cause off-specification gas, alarm conditions or automatic shutdown

Service: Inspect treatment vessels or generators, pumps, fans or blowers, spray or filtration equipment, analyzers, drains and control interlocks. Trend gas quality, pressure drop and liquid-treatment condition where applicable. Verify shutdown and isolation functions according to the approved procedure. Refer to manufacturer, vessel and statutory documentation for the exact figure for gas quality, emissions, pressure and chemical limits.

Spare Parts: Carry pump and valve seals, analyzer consumables, filters, spray nozzles, dosing parts, fan or blower service items, sensors and control relays.

Strengths

Provides continuous on‑board nitrogen at ≥99.5% purity, reducing reliance on shore‑supplied LN₂
Compact footprint and lower weight compared with cryogenic generators
Integrated with existing compressed‑air system; only requires clean, dry air
Proven Atlas Copco brand reliability and service network
Automatic valve inspection schedule (annual) simplifies maintenance planning

Weaknesses

Performance is directly tied to the quality of inlet compressed air; oil carry‑over can impair purity
Known failure modes include CMS adsorbent bed channeling and switching‑valve malfunction, requiring vigilant monitoring
Maximum flow rate may be lower than that of large cryogenic nitrogen plants for very high‑capacity tankers
Adsorbent beds require periodic replacement or regeneration, adding lifecycle cost
Initial capital expense is higher than simple air‑blowing inert gas systems

Typical Vessels: Oil TankerChemical TankerLPG CarrierProduct Tanker

Decision Guide: Choose if: you need a reliable, high‑purity nitrogen source on board and have an existing clean dry compressed‑air system; vessel operates under IMO inert‑gas regulations and prefers reduced logistics for LN₂. Avoid if: the ship cannot guarantee oil‑free air quality, requires very high nitrogen flow rates beyond PSA capacity, or seeks the lowest upfront cost solution.

Use Cases: SOx control, tanker inerting, nitrogen generation and cargo-atmosphere management.

Strengths

No moving parts in the separator – very low mechanical wear and maintenance
Compact footprint and relatively light compared with compressor‑type generators
Fast start‑up; can deliver inert gas on demand within minutes
Energy efficient for moderate flow rates, reducing ship power consumption

Weaknesses

Flow capacity limited relative to large PSA/compressor systems – may be undersized for very large tankers
Membrane fibers are susceptible to degradation over time, requiring periodic replacement
Performance drops sharply if moisture or oil carry‑over is not tightly controlled
Pre‑filter blockage can cause pressure loss and reduced nitrogen output

Typical Vessels: Product tankerChemical tankerSmall to medium crude carrier (up to ~30,000 dwt)Offshore supply vesselLNG/LPG carrier (as supplemental inert gas source)

Certifications: IMO D‑2 inert gas system approvalDNV GL type approval

Decision Guide: Choose if you need a compact, low‑maintenance nitrogen generator for moderate inert‑gas demand and want to avoid the complexity of flue‑gas IG or large PSA units. Avoid if the vessel requires very high flow rates (>2000 Nm³/h), operates in environments with high moisture/oil carry‑over, or if membrane replacement cycles are not acceptable.

Use Cases: SOx control, tanker inerting, nitrogen generation and cargo-atmosphere management.
