Marine Membrane Nitrogen Generator

Marine Membrane Nitrogen Generator

Product Introduction:

The generator uses compressed air as feed stock. Air enters one or more membrane modules, each containing millions of hollow‑fibre membranes. Different gases permeate through the fibre walls at different rates: oxygen, water vapour, and carbon dioxide diffuse rapidly and are vented as permeate, while nitrogen (with a slower permeation rate) is retained and delivered from the module outlet as the product gas. Since argon permeates even more slowly, the final product is a nitrogen‑rich stream with a small argon content - fully adequate for most marine inerting and blanketing duties.

Technical Specifications:

Key Features & Advantages:

1.No moving parts - the membrane system operates statically, offering extremely high reliability and minimal maintenance.

2.Instant start‑up - reaches specified purity within seconds of air supply, with no warm‑up or regeneration time.

3.Compact and lightweight - ideal for space‑constrained marine installations; skid‑mounted for easy integration.

4.Adjustable performance - purity and flow can be fine‑tuned by regulating feed pressure or product back‑pressure to match varying operational demands.

5.Low dew point - guaranteed ≤ -65°C ensures dry nitrogen, preventing corrosion and ice formation in cold service.

6.Robust in harsh environments - designed to withstand vibration, humidity, and salt‑laden atmospheres typical of ships and offshore platforms.

Typical Marine Applications:

*Inert gas generation for cargo tank blanketing (oil/chemical/LPG/LNG carriers).

*Purging and drying of pipelines and storage tanks.

*Pressure maintenance for hydraulic accumulators and pneumatic controls.

*Fire suppression and inerting during loading/unloading operations.

*Supply of instrument‑quality dry nitrogen for analysers and valve actuation.
