Canisters containing argon gas for use in extinguishing fire in a server room without damaging equipment. Gaseous fire suppression, also called clean agent fire suppression, is the use of inert gases and chemical agents to extinguish a fire.
Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. [10] Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv).
The HIP process subjects a component to both elevated temperature and isostatic gas pressure within a high-pressure containment vessel, unlike the cold isostatic pressing(CIP), where the component is maintained at room temperature. [2] The pressurizing gas most widely used is argon. An inert gas is used so that the material does not chemically ...
The Southern Environmental Law Center filed the long-promised lawsuit in Fairfax County Circuit Court to try to keep Virginia in the Regional Greenhouse Gas Initiative, also known as RGGI, which ...
Washington Gas' Amended Application for Replacement of Aging Infrastructure Approved by Virginia State Corporation Commission WASHINGTON--(BUSINESS WIRE)-- On November 15, 2012, the Virginia State ...
For instance, argon, krypton, and xenon form clathrates with hydroquinone, but helium and neon do not because they are too small or insufficiently polarizable to be retained. [61] Neon, argon, krypton, and xenon also form clathrate hydrates, where the noble gas is trapped in ice. [62] An endohedral fullerene compound containing a noble gas atom
Use of modern structured packings which have very low pressure drops enable argon with less than 1 ppm impurities. Though argon is present in less to 1% of the incoming, the air argon column requires a significant amount of energy due to the high reflux ratio required (about 30) in the argon column.
An asphyxiant gas, also known as a simple asphyxiant, is a nontoxic or minimally toxic gas which reduces or displaces the normal oxygen concentration in breathing air. Breathing of oxygen-depleted air can lead to death by asphyxiation (suffocation).
