A nitrogen inerting system for large oil tankers is described. Although more expensive than a flue gas inerting system, the nitrogen inerting system requires less maintenance, is free from corrosion, and above all, is inherently absolutely safe. With this system, only one-half of one percent of oxygen is present in the inerting gas, as opposed to greater quantities of oxygen and other contaminents that are found in the flue gas system. For nitrogen plants aboard large tankers, a unit is available that is capable of producing inert nitrogen gas from stored liquid nitrogen and low pressure compressed air. This process is described fully, and it is able to produce flows of up to 30,000 m cubed/hr.
