The inerting systems use an inert gas generator to supply inert make-up gas instead of air. This procedure is often referred to as inerting. Technically, the procedure ensures that the atmosphere in the tank's headspace remains unignitable. The gas mixture in the headspace is not inert per se, it's just unignitable. Because of its content of ...
The system can be flushed with an inert gas to reduce the concentration of oxygen so that when the flammable gas is admitted, an ignitable mixture cannot form. In NFPA 56, [1] this is known as purge-into-service. In combustion engineering terms, the admission of inert gas dilutes the oxygen below the limiting oxygen concentration.
The inert-gas line is vented through an oil bubbler, while solvent vapors and gaseous reaction products are prevented from contaminating the vacuum pump by a liquid-nitrogen or dry-ice/acetone cold trap. Special stopcocks or Teflon taps allow vacuum or inert gas to be selected without the need for placing the sample on a separate line. [3]
Inert gas can also be used to purge the tank of the volatile atmosphere in preparation for gas freeing - replacing the atmosphere with breathable air - or vice versa. The flue gas system uses the boiler exhaust as its source, so it is important that the fuel/air ratio in the boiler burners is properly regulated to ensure that high-quality inert ...
The inerting systems will probably prevent 8 of those 9 probable explosions, the FAA said. Before the inerting system rule was proposed, Boeing stated that it would install its own inerting system on airliners it manufactures beginning in 2005. Airbus had argued that its planes' electrical wiring made the inerting system an unnecessary expense.
Dozens of water systems either had boil advisories in place because of low pressure or warned of bigger catastrophes if leaks from broken pipes weren't found and water shut off.
An ordinary glovebox, showing the two gloves for manipulation, with airlock on the right. The most straightforward type of air-free technique is the use of a glovebox.A "glove bag" uses the same idea, but is usually a poorer substitute because it is more difficult to purge, and less well sealed.
