What are the requirements for Inert Gas or IG Plant on Tanker Ships?

1. The inert gas generator-

Exhaust gas from the main boiler or the auxiliary boiler is used.

2. Scrubber

This is installed to clean and cool the exhaust gas.

3. Demister

This is installed to separate water and solid contained in the inert gas coming from the scrubber sucked by the fan.

4. IG fan

This is a single stage centrifugal blower driven by the motor, which draws out the gas coming through the uptake of the boiler and sends it out to the deck seal unit through the scrubber and demister.

5. Control valve

This valve adjusts the pressure in the inert gas line in accordance with the pre set pressures.
