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
Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
The basic oxygen steel-making process is as follows: Molten pig iron (sometimes referred to as "hot metal") from a blast furnace is poured into a large refractory-lined container called a ladle . The metal in the ladle is sent directly for basic oxygen steelmaking or to a pretreatment stage where sulfur , silicon , and phosphorus are removed ...
[1] [2] [3] In most jurisdictions, Station Outlets are required to be equipped with safety systems that prevent cross-connection errors, such as connecting a Medical air flowmeter to an Oxygen port. Hospitals mainly use DISS connections, though a wide variety of quick-connect adapters, based on male strikers and female outlet ports, are still ...
The YF-73 was China's first successful cryogenic liquid hydrogen fuel and liquid oxygen oxidizer gimballed engine.It was used on the Long March 3 H8 third stage, running on the simple gas generator cycle and with a thrust of 44.15 kilonewtons (9,930 lb f).
Electrolysis of water is the decomposition of water (H 2 O) into oxygen (O 2) and hydrogen (H 2): [2] Water electrolysis ship Hydrogen Challenger. Production of hydrogen from water is energy intensive. Usually, the electricity consumed is more valuable than the hydrogen produced, so this method has not been widely used.
At first, liquid air, self-enriched by standing (nitrogen has a lower boiling point and evaporates preferentially) was used, but pure liquid oxygen gives better results. A mixture of lampblack and liquid oxygen was measured to have a detonation velocity of 3,000 m/s, and 4 to 12% more explosive power than dynamite. The long duration of the ...
A vacuum insulated evaporator (VIE) is a form of pressure vessel that allows the bulk storage of cryogenic liquids including oxygen, nitrogen and argon for industrial processes and medical applications. [1] The purpose of the vacuum insulation is to prevent heat transfer between the inner shell, which holds the liquid, and surrounding ...
