Skid-Mounted N2 System For Oil & Gas

The skid-mounted N2 system for oil & gas is a highly integrated, rapidly deployable modular nitrogen generation solution. This system mounts the air compressor, purification unit, nitrogen membrane modules or pressure swing adsorption (PSA) unit, control panel, and analyzers as a complete package onto one or multiple reinforced steel skid structures. Its core design objective is to provide a stable, reliable, and continuous nitrogen supply in harsh field operating environments, meeting the various inert gas requirements of oil and gas fields throughout the entire lifecycle from development and production to maintenance.

This system employs mature and reliable Pressure Swing Adsorption (PSA) or membrane separation technology. PSA technology utilizes the difference in adsorption rates of oxygen and nitrogen on carbon molecular sieves, achieving nitrogen-oxygen separation through cyclic pressure changes. Membrane separation technology relies on the differing gas permeabilities through hollow fiber membranes to extract nitrogen. The skid-mounted design modularizes and integrates all equipment within the process flow, including:

1. Air Intake & Treatment Module: Air compressor and pre-filters, providing clean compressed air.
2. Purification & Separation Module: Precision filtration, drying unit, and the core PSA towers or membrane separation assemblies.
3. Control & Monitoring Module: Intelligent PLC control system for real-time monitoring of purity, flow, pressure, and equipment status.
4. Output Module: Nitrogen buffer tank, final polishing filters, and pressure regulation system.

This integrated skid-mounted N2 system for oil & gas structure significantly reduces on-site piping and wiring work, ensuring system consistency and reliability.

The table below lists typical technical specifications for this system. Specific parameters can be customized according to project requirements.

This skid-mounted N2 system is widely used in the oil and gas industry:

• Pipeline Operations: Hydrotesting, purging of new pipelines; pigging and drying of in-service pipelines.
• Tank Maintenance: Inerting protection for floating roof and fixed roof tanks, preventing VOC emissions and combustion risks.
• Wellhead Operations: Gas lift and wellbore purging during completion, workover, and fracturing processes.
• Enhanced Oil Recovery (EOR): For nitrogen injection EOR projects.
• Liquefied Natural Gas (LNG): Inerting protection for LNG facilities and transportation.

System design and manufacturing adhere to international mainstream standards, ensuring safety and mutual recognition:

• Pressure vessel and piping design/manufacture comply with ASME BPVC Section VIII.
• Quality Management System is certified to ISO 9001:2015.
• Electrical components meet IECEx or ATEX explosion-proof requirements (as specified for client region).
• All equipment undergoes complete Factory Acceptance Testing (FAT) prior to shipment, with detailed test reports provided.
