Inert gas generator and flue gas system for ships
DGIN Aalborg Industries

The SMIT GAS™ DGin inert gas generator (IGG) utilizes the exhaust gas from the diesel engine as combustion air for its Ultramizing® burner. As the oxygen content is already low(ered) in the exhaust gas (normally approx. 13% O2 compared to approx. 21% O2 in atmospheric air), less fuel is required for the DGin generator to produce the necessary quality (> 5% O2) of inert gas for tank inerting, and fuel savings of up to 35% for the IGG are
possible. This means reduced emissions and a sharply reduced fuel bill.

The SMIT GAS™ DGin inert gas generator plant consists of three main components:

* A venturi scrubber for removing soot
* A packed column with demister for removing SOx and droplets
* A flue gas fan that supplies the low O2 content diesel exhaust to the inert gas generator
