Inerting (gas) - Wikipedia
In fire and explosion prevention engineering, inerting refers to the introduction of an inert (non-combustible) gas into a closed system (e.g. a container or a process vessel) to make the atmosphere oxygen deficient and non-ignitable. Inerting relies on the principle that a combustible (or flammable) gas is able to undergo combustion (explode) only if mixed with air in the right proportions ...
Inert nanoparticle suppression of gas explosion in …
The suppressing effects of inert nanoparticles on methane–air explosion, in an obstructed chamber with internal dimensions of 150 mm × 150 mm × 500 mm, were experimentally investigated. To this end, the flame behaviors in the presence of obstacles as well as overpressure transients during the explosions …

01.11.2019 · The apparatus was verified in accordance with EN1839. The deviations lay within the uncertainty values given in EN1839. 3. Results and discussion 3.1. Explosion limits of combustibles in air without inert gas at different temperatures. The data in Table 1 shows the LEL and UEL of the combustibles tested in air and compares them to literature data for which comparable procedures (apparatus ...
Effects of inert steam on upper explosion limit for ...
28.05.2010 · In this work, oxygenated hydrocarbons were inertized by inert steam, and the relation of the upper explosion limit and the extent of the inertization was explored. With the assumption that the adiabatic flame temperatures are the same for all limit mixtures, it was found that the aforementioned linear relation still holds in case the inert gas is of steam and the flammable material is of oxygenated …

What is inertization / inert gas? Definition
The inert gas is introduced into the space that should be protected from explosion. The presence of the inert gas reduces the oxygen volume fraction below the limiting oxygen concentration (LOC) or the maximum allowable oxygen concentration (MAOC) so that the mixture can no longer ignite. Safety measures for the use of inert gases . During inertization, MAOC should not be exceeded at any time ...
A method and apparatus for suppressing …
29.06.1994 · Apparatus for suppressing explosions comprises a reservoir means (5,25) containing hot pressurised water which is heated by a heating means (9,28). On explosion conditions occurring in an enclosure (2,20,21,22) a high speed differential pressure diaphragm (10,40) is fractured to release a charge of hot pressurised water into the enclosure. When the water enters the enclosure portion it is ...

Schlenk line - Wikipedia
The inert-gas line is vented through an oil bubbler, ... An implosion can occur due to the use of vacuum and flaws in the glass apparatus. An explosion can occur due to the common use of liquid nitrogen in the cold trap, used to protect the vacuum pump from solvents. If a reasonable amount of air is allowed to enter the Schlenk line, liquid oxygen can condense into the cold trap as a pale blue ...
