NITROGEN FOR INERTING

A case for the use of nitrogen for inert gas systems is presented. Since the nitrogen gas is the cleanest of all inerting gases, and since it does not contain any carbon dioxide, heavy metal oxides, soot, or sulphur oxides, it must be considered safer than any other inerting gas. Nitrogen removes the concern that water and carbon dioxide will solidify or react with the cargo, and it will not cause corrosion in the tank. Sources of obtaining nitrogen gas are described, and they include shore based liquid nitrogen, and on board generation of nitrogen gas. Also included in the article are descriptions of vessels and their required inerting gas flow rates, as well as operating cost factors when using nitrogen as the inerting gas.
