Business Introduction

ALL PRODUCT
N2-GEN is a Marine Inert Gas (Nitrogen) Supply system.
N2-GEN provides specialized gas processing systems for ships and offshore installations.
As a reliable supplier of onboard nitrogen systems, we meet the comprehensive applications and technical requirements of inerting systems for LNG, chemical, and oil carriers, and others.
Applications
N2-GEN is a continuous and trouble-free supply system of Nitrogen on board for the following applications:

Chemical tankers

LNG carriers

LPG carriers

FGSS or other dried inert gas demand

Features
PSA (Pressure Swing Adsorption) type inert gas generator has the following features and advantages over other types.

Cost-effectiveness

Higher purity

Wide capacity ranges

Low maintenance costs

Small footprint

Low Energy consumption

Low water contents

Fully automated control






Working Principles
The operation of N2-GEN is based on the Pressure Swing Adsorption (PSA) principle, utilizing high-quality carbon molecular sieves as the adsorbent to separate nitrogen and oxygen. The adsorbent adsorbs oxygen, carbon dioxide, and water vapor, while nitrogen passes through the adsorption layer and is separated. The system is composed of a service column and a standby column, which are periodically alternately regenerated to supply a continuous high-quality nitrogen. Regeneration and service operations are automatically controlled, and the high-quality carbon molecular sieve provides long-term durability.
