NiGen specializes in applications utilizing on-site nitrogen generators for the pipeline industry and the broader oil and gas sector. We have successfully provided services for thousands of pipeline miles using the latest nitrogen membrane technology. Our technical team supports both ongoing operations and new pipeline construction projects.
As a specialized pipeline maintenance company, our core capabilities include:
- Pigging and Purging: Utilizing dry air or nitrogen to propel SMART pigs, cleaning pigs, or displacement pigs.
- Commissioning and Decommissioning: Developing rigorous procedures for systems ranging from 2″ to 42″ in diameter.
- Inerting and Drying: Achieving negative dew point readings as low as -100°F for moisture-sensitive systems.
- Integrity Testing: Providing pneumatic testing, leak detection, and chemical cleaning.
On-Site Nitrogen for Pipeline Services
The nitrogen used for pipeline displacement varies from 92% to 100% purity, depending on the product. Ethylene and butadiene pipelines require 99%-99.9% purity, while crude oil applications typically range from 94%-98%.
On-site nitrogen generators using membrane technology provide a cost-effective alternative in remote locations where liquid nitrogen is impractical. NiGen systems are lightweight, reliable, and containerized for onshore and offshore field services.
Equipment Rentals for Pipeline Services
As a full-service pipeline maintenance company, we provide the following specialized equipment rentals for onshore and offshore operations:
- Portable diesel air compressors
- Air dryers (desiccant)
- Booster compressors
- Atmospheric vent silencers
- Air coolers and portable fuel tanks
- Nitrogen generator rentals
Experience & Capabilities
NiGen has helped pipeline companies develop commissioning and decommissioning procedures and has completed onshore and offshore projects for major pipeline companies. Past projects have ranged from 1 to 1,100 miles and 2″ to 42″ in diameter, covering diverse terrains. Our solutions are ideal for both existing systems and new pipeline construction initiatives in the oil and gas industry.
The nitrogen used for pipeline displacement varies from 92% to 100% purity, depending on the product. Ethylene and butadiene pipelines require 99%-99.9% purity, while crude oil applications range from 94%-98%.
We handle last-minute projects, dewatering, and drying, ensuring negative dew point readings as low as -100°F when required. On-site nitrogen generators using membrane technology is a cost-effective alternative in remote locations where liquid nitrogen may be impractical.
Technical Consultation for Pipeline Maintenance
To assess the specific requirements for your maintenance or construction project, we evaluate:
- Clearing Requirements: Does the line need pigging or product displacement?
- System Geometry: What are the access points, connection types, and elevations?
- Post-Test Procedures: Can the system be dried effectively after hydrostatic or pneumatic testing?
In addition to standard operations, NiGen is also capable of providing specialized repair services to address urgent issues or operational breakdowns, ensuring continuous functionality of your pipeline infrastructure.
