On-Site Gas Generation

Nitrogen Generators

Gulf Union Ozone supplies PSA and membrane nitrogen generators, liquid nitrogen vaporisers, N₂ boosters and buffer tanks for Saudi Arabia oil & gas, petrochemical, pharmaceutical and food-processing industries. On-site nitrogen generation eliminates the cost, logistics and safety hazards of delivered cylinder or liquid nitrogen supply, reducing the cost of N₂ to SAR 0.8–1.5 per Nm³ compared with SAR 4–8/Nm³ for cylinder delivery. Pressure-swing adsorption (PSA) generators use carbon molecular sieve beds to separate nitrogen from compressed air, producing 95–99.999% purity N₂ with automatic bed-switching for continuous uninterrupted output. Membrane generators use hollow-fibre polymer modules — no moving parts, minimal maintenance, purity 95–99.5% — ideal for pipeline purging, tank blanketing and tyre inflation. Liquid nitrogen vaporisers (ambient, electric-heated and steam-heated) convert bulk LN₂ from ISO storage tanks to high-purity gaseous nitrogen for laboratory, pharmaceutical and cryogenic food-freezing applications at Saudi facilities. Air-driven and motor-driven boosters raise generator outlet pressure to 20–300 bar for cylinder filling, gas-assisted injection and accumulator charging. ASME Section VIII buffer tanks (50–5000 litre, carbon steel and stainless) manage demand surges. Online paramagnetic, zirconia and thermal-conductivity purity analysers verify N₂ quality continuously. ATEX Zone 2 generator packages available for hazardous-area installation on Saudi Aramco and SABIC plants. ISO 9001:2015 certified, CR 4030570569, Jeddah.

PSA and membrane nitrogen generators for industrial and oil and gas use in Saudi Arabia — Gulf Union Ozone Jeddah

Nitrogen Generator Categories

Product Types in Stock

Gulf Union Ozone carries six nitrogen generation and handling product families for Saudi Arabia oil & gas, petrochemical, pharmaceutical and industrial applications, with ISO 8573-1 purity class documentation and full certification for every supply.

Type 01

PSA Nitrogen Generators

Pressure-swing adsorption generators producing 95–99.999% N₂ purity from compressed air; modular carbon-molecular-sieve beds with automatic cycle switching for continuous output at Saudi plants. Dual-bank CMS bed design ensures uninterrupted nitrogen during adsorbent regeneration cycles; skid-mounted with integrated air receiver, filters, dryer and PLC control; ATEX Zone 2 packages available for Saudi Aramco and SABIC hazardous-area installation.

Type 02

Membrane Nitrogen Generators

Hollow-fibre membrane modules producing 95–99.5% N₂; compact units with no moving parts ideal for blanket-gas and pipeline purging applications in Saudi Arabia. Polymer hollow-fibre bundles selectively permeate oxygen and moisture from compressed air to produce nitrogen at the non-permeate outlet; no valves, no bed-switching, minimal maintenance; suitable for remote Saudi field installations with no service infrastructure.

Type 03

Liquid Nitrogen Vaporisers

Ambient and heated (electric or steam) LN₂ vaporisers for converting bulk liquid nitrogen to gas for laboratory, food-freezing and pharmaceutical use at Saudi facilities. Ambient-air aluminium vaporisers require no external energy source; electric-heated and steam-heated vaporisers maintain output in hot-standby mode or during high-demand periods; all supplied with pressure regulator, safety relief valve and outlet gas analyser option.

Type 04

Nitrogen Boosters

Air-driven and motor-driven nitrogen boosters that raise PSA-generator outlet pressure from 7 to 300 bar for cylinder filling, gas-assisted injection and accumulator charging. Air-driven boosters are intrinsically safe (no electrical supply required in the hazardous area) and infinitely variable in output pressure; motor-driven boosters provide higher continuous flow for Saudi Arabia cylinder filling stations and testing laboratory supply.

Type 05

N₂ Buffer Tanks

ASME Sec VIII carbon steel and stainless buffer vessels (50–5000 litre, 10–300 bar) for nitrogen storage and demand surge management downstream of generators. Horizontal and vertical orientations; code-stamped with ASME pressure vessel certificate; supplied with safety relief valve, pressure gauge, drain valve and isolation valve; stainless steel SS 316L vessels available for pharmaceutical, food and corrosive-environment applications.

Type 06

Purity Analysers

Online paramagnetic and thermal-conductivity oxygen analysers for continuous N₂ purity monitoring; 4–20 mA output and HART protocol compatible with Saudi plant DCS. Paramagnetic analysers measure oxygen by its response to a magnetic field — highly selective and drift-free; zirconia sensors measure ppm-level O₂ for high-purity PSA verification; thermal-conductivity sensors provide cost-effective monitoring for blanketing and general utility nitrogen.

Frequently Asked Questions

Nitrogen Generators in Saudi Arabia — Common Questions

What N₂ purity is required for pipeline purging in Saudi Aramco projects?

Saudi Aramco SAES-L-450 (Displacement, Purging, Pressure Testing and Leak Testing of Piping Systems) typically specifies residual oxygen below 1% (10 000 ppm) for a safe pipeline purge before introduction of hydrocarbons. For inerting prior to hot-work in confined spaces, oxygen must be reduced below 0.5% per SAES-B-058. A membrane nitrogen generator producing 99.5% N₂ (5000 ppm O₂) is sufficient for most purge applications; PSA at 99.99% is used where stricter inerting is required.

How do PSA and membrane nitrogen generators compare for Saudi oil & gas applications?

PSA generators produce higher purity nitrogen (up to 99.999%) at lower energy consumption for a given purity above 98%, making them preferred for instrument gas, blanketing of high-value products and catalyst protection. Membrane generators are simpler (no moving parts, no valves), quieter and require less maintenance, but are limited to around 99.5% purity; they suit pipeline purging, tyre inflation and general blanketing at lower cost. For Saudi oil & gas, PSA is standard for process-critical duties and membrane for utility applications.

Can nitrogen generators be used in ATEX classified areas on Saudi plants?

Yes. Gulf Union Ozone supplies PSA and membrane nitrogen generators with ATEX Zone 2 (gas) classification for installation in hazardous areas on Saudi oil and gas facilities. The package includes ATEX-certified electrical enclosures, pressure control valves and solenoid valves rated for Zone 2 duty per IEC 60079. Saudi Aramco SAES-B-068 (Area Classification) and SAES-B-006 (Electrical Equipment) requirements are met. Compressors and dryers are located in a safe area with N₂ piped to the hazardous zone.
