Liquid oxygenator

Linde process A high-pressure process for the production of liquid oxygen and nitrogen by compression to about 200 bar (20MN/m ) followed by refrigeration and fractionation in a double column. 

Explosives based on liquid oxygen and a fuel, generally carbon black.

Oxygen, like nitrogen oxide, NO, shows little tendency to dimerise although the presence of the unstable, weakly bonded species, tetratomic oxygen O4, has been reported as a constituent of liquid oxygen.

Oxygea is a commodity sold either as a gas uader pressure or a very low temperature Hquid close to its boiling poiat. Because of the expease of the coataiaers required, it caimot be stored ia more than modest amounts nor can it be shipped profitably more than a few hundred kilometers. Liquid oxygen storage faciHties are limited to volumes on the order of 4000 m. ... 

In contrast to other cryogenic fluids, liquid oxygen is slightly magnetic. It is also chemically reactive, particularly with hydrocarbon materials. Oxygen thus presents a safety problem and requires extra precautions in handling. 

In the cycle shown, gaseous oxygen and nitrogen are withdrawn at room temperature. Liquid oxygen could be withdrawn from point A and liquid nitrogen from point E, but in this case more refrigeration would oe needed. 

Trace impurities in the feed streams can lead to combination of an oxidant with a flammable material (e.g. acetylene in liquid oxygen, solid oxygen in liquid hydrogen) and precautions must be taken to eliminate them. 

Liquid oxygen is pale blue, slightly heavier than water, magnetic, non-flammable and does not produce toxic or irritating vapours. On contact with reducing agents, liquid oxygen can cause explosions.

Also, beeause the boiling points of these eryogenie liquids are lower than that of oxygen, if exposed to air they ean eause oxygen to eondense preferentially, resulting in hazards similar to those of liquid oxygen. 

Ammonia can also react violently with a large selection of chemicals including ethylene oxide, halogens, heavy metals, and oxidants such as chromium trioxide, dichlorine oxide, dinitrogen tetroxide, hydrogen peroxide, nitric acid, liquid oxygen, and potassium chlorate. 

Preliminary minimum distances Liquid oxygen Liquefied flammable gases Liquids stored at ambient temperature and pressure A Code of Practice for the Bulk Storage of Liquid Oxygen at Production Sites (HSE, 1977) Process Plant Layout page 562 (Mecklenburgh, 1985) Process Plant Layout page 564... 

Liquified gases are sometimes stored in well-insulated spherical containers that are vented to the atmosphere. Examples in the industry are the storage of liquid oxygen and liquid ammonia in spheres. If the radii of the inner and outer walls are r, and r, and the temperatures at these sections are T, and T, an expression for the steady-state heat loss from the walls of the container may be obtained. A key assumption is that the thermal conductivity of the insulation varies linearly with the temperature according to the relation ...
