Statement of Work High-Pressure High-Purity Nitrogen Generator rev2

Portable Special-Purpose High-Purity (<50 ppm) Nitrogen Generation System
Document ID: PSNS-SPEC-N2-4500
Facility: Puget Sound Naval Shipyard & Intermediate Maintenance Facility (PSNS & IMF)
Classification: Technical Acquisition Specification

1. System Overview and Purpose

This documents the minimum mandatory performance, design, automation, layout, and safety requirements for a turn-key, portable, combined containerized highpurity nitrogen generation with a high-pressure booster gas compression and storage
The system shall be deployed in a heavy industrial maritime environment to supply high-pressure, generated gaseous nitrogen w/inert gas components to exterior storage banks. The system accepts shipyard-provided compressed Grade D breathing air or operates autonomously via self-supplied feed air, separating nitrogen to high purity (< 50 ppm O2 ), and boosts the output using a high-pack booster compressor directly to a delivery pressure of 4,500 psig. All generation, compression, automated manifolding, controls, and maintenance storage should preferably be fully contained within a single ISO 668 Type 1C (20ft) intermodal container, while the high-pressure bottle bank/s can be standalone but included with the system.

2. Gas Supply and Purity Requirements

2.1 Gas Quality Specifications

The generated gas supply shall meet or exceed all requirements for Type 1, Grade A Gaseous Nitrogen per Federal Specification CID A-A-59155, with a mandatory enhanced oxygen limitation:
•
•

Oxygen (O2 ) Content: < 50 ppm by volume (≥ 99.995% Nitrogen/Argon, Grade A enhanced).
Moisture Content: Maximum 0.02 mg/L (equivalent to 26.3 ppm water vapor by volume, dew point −63.5∘ F/−53∘ C or drier).

•
•
•
•
•

Particulate Cleanliness: Free of particles > 50 microns; final supply filtration assured by an inline 10-micron or finer filter.
Hydrocarbon (Gas) Content: < 50 ppm as Methane by volume. Oil Content: 100% oil-free gas delivery.
Odor: None detectable.
Argon, Neon, and Helium: Trace quantities permissible per CID A-A-59155.

2.2 Qualification Testing and Pre-Delivery Certification

1. NRTL Certification: The complete integrated assembly shall demonstrate full required operation and pass an OSHA-accredited Nationally Recognized Testing Laboratory (NRTL) field evaluation and inspection prior to delivery. 2. Purity Verification: Prior to shipment, gas purity shall be verified by an accredited independent testing laboratory using samples collected directly from
