Marine Membrane Nitrogen Generator

The SINNA GAS Marine Membrane Nitrogen Generator is a high-performance onboard nitrogen generation system engineered for marine and offshore environments. Utilizing advanced hollow-fiber membrane separation technology, the system continuously produces nitrogen from compressed air, providing a safe, reliable, and cost-effective alternative to nitrogen cylinders and liquid nitrogen supply.

Designed for cargo tank inerting, tank blanketing, pipeline preservation, purging, pressure transfer, and fire prevention applications, the system delivers stable nitrogen purity while minimizing maintenance and operating costs. Its compact footprint, corrosion-resistant construction, and fully automatic operation make it ideal for installation on tankers, LNG carriers, chemical vessels, offshore platforms, FPSOs, and other marine facilities.

With years of experience in nitrogen generation technology, SINNA GAS provides customized marine nitrogen solutions tailored to vessel specifications, operational requirements, and classification society standards.

Continuous Onboard Nitrogen Supply: Generate nitrogen anytime and anywhere without dependence on external gas deliveries.

Compact Marine Design: Space-saving skid-mounted configuration suitable for vessels with limited installation space.

Low Operating Cost: Eliminates recurring expenses associated with nitrogen cylinders and liquid nitrogen logistics.

Marine-Grade Reliability: Designed to withstand vibration, humidity, salt-laden air, and harsh offshore operating conditions.

Fully Automatic Operation: PLC-based control system with automatic monitoring, alarm management, and safety protection.

Adjustable Nitrogen Purity: Flexible nitrogen purity levels available to meet various marine applications.

Low Maintenance Requirements: Membrane modules contain no moving parts, ensuring long service life and minimal maintenance.

Fast Start-Up: Nitrogen production begins within minutes after system startup.

The system utilizes selective gas permeation technology to separate nitrogen from compressed air.

Compressed air first passes through multiple filtration stages where oil, moisture, dust, and contaminants are removed. The purified air then enters high-performance membrane modules.

Within the membrane fibers, oxygen, water vapor, and carbon dioxide permeate through the membrane walls more rapidly than nitrogen. As these gases are removed, nitrogen becomes concentrated and exits the membrane module as the product gas.

The resulting nitrogen is delivered directly to the vessel's nitrogen distribution network for immediate use.

This process is continuous, efficient, and highly reliable, making membrane technology an ideal solution for marine applications.

Cargo Tank Inerting: Maintain low oxygen concentration levels inside cargo tanks to reduce explosion and fire risks.

Tank Blanketing: Protect stored products from oxidation, contamination, and moisture intrusion.

Pipeline Preservation: Prevent internal corrosion during shutdown, maintenance, and transportation periods.

LNG and LPG Carrier Operations: Support purging, drying, and inerting procedures.

Offshore Platforms and FPSOs: Provide nitrogen for maintenance, preservation, and process safety applications.

Chemical Tankers: Protect sensitive cargoes and maintain product quality throughout transportation.

Fire Prevention Systems: Create oxygen-deficient environments to reduce combustion hazards.

Equipment Preservation: Protect machinery, process vessels, and pipelines from corrosion and moisture damage.

Customized specifications are available upon request.

Lower Lifecycle Cost: Compared with traditional nitrogen cylinders and liquid nitrogen supply, onsite nitrogen generation significantly reduces operating expenses by eliminating transportation, storage, and replenishment costs.

High System Availability: With no moving parts inside the membrane modules, the system achieves excellent operational reliability and availability exceeding 99% under recommended operating conditions.

Long Service Life: High-quality membrane modules are designed for long-term continuous operation, typically providing 8–10 years of service life.

Safe and Environmentally Friendly: The system generates nitrogen directly from ambient air without chemicals, cryogenic liquids, or hazardous consumables.
