Oil & Gas Applications

Fixed or mobile nitrogen systems for oil and gas applications

Oil & Gas activities require nitrogen (N2) for inerting, pipeline servicing, commissioning and decommissioning jobs, underbalanced drilling, enhanced oil recovery, coil tubing, gas lifting and blanketing. Increasing remote activities and offshore fields are driving the demand towards more membranes on board of vessels or platforms. In addition to being an on-demand, low maintenance and reliable source of nitrogen, onsite membrane-based nitrogen systems reduce pressure to the supply chain.

Small N2 Production System

Air Liquide small nitrogen (N2) production system is a fully integrated system that provides a continuous supply of N2 as demand changes. It is a reliable, low-cost N2 supply solution when cryogenic purity is not required. Small integrated N2 standard systems offers plug and play installation with full purity insurance. Most generally recommended for offshore operation and but also for maritime installation.

Technical Features:

  • Purity range 95% to 99.9%
  • Flow rates 10 Nm3 / hr to 400 Nm3 / hr
  • Maximum operating temperature 55°C
  • Moisture Content < 10 ppm (< 1 ppm optional)
  • Oil Content < 0.003 ppm (not measurable)
  • Particulates < 0.01 micron
  • Power:
    • 60 HZ: 440 / 460v, 3 phase
    • 50 HZ: 380 / 415v, 3 phase

Standards:

  • Pressure: ASME BPVC VIII Div1
  • Electrical IEC or NEC
  • ISO 9002 certified process
  • International certification available (ABS, DNV) - Hazardous (ATEX 2 / Class I Div 2) upon request
  • Systems available with / without air compressor – Air / N2 receiver upon customer request

Large N2 Production System

Air Liquide large N2 production system is a fully integrated system with large capacity that provides continuous supply of nitrogen as demand changes. It is a reliable, low cost supply solution when cryogenic purity is not required. Large integrated N2 standard systems offers plug and play installation with full purity assurance. Well adapted for offshore and maritime environment.
