The term oxygen generator is a misnomer in that the oxygen is not generated as it is with a chemical oxygen generator, but rather it is concentrated from the air. Non-medical oxygen concentrators can be used as feed gas to a medical oxygen system, such as the oxygen system in a hospital, though governmental approval is required, such as by the ...
Ozone generators are designed to produce ozone and are sometimes sold as whole-house air cleaners. Unlike ionizers, ozone generators are intended to produce significant amounts of ozone, a strong oxidant gas which can oxidize many other chemicals. The only safe use of ozone generators is in unoccupied rooms, utilising "shock treatment ...
Ozone production demonstration, Fixed Nitrogen Research Laboratory, 1926. Ozone generators, or ozonators, [133] are used to produce ozone for cleaning air or removing smoke odours in unoccupied rooms. These ozone generators can produce over 3 g of ozone per hour. Ozone often forms in nature under conditions where O 2 will not react. [29]
A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture.
However, the required concentrations are sufficiently toxic to humans and animals that the U.S. FDA declares that ozone has no place in medical treatment [10] and has taken action against businesses that offer ozone generators or ozone therapy to consumers. [11] Ozone is a highly toxic and extremely reactive gas. [12]
Ozone production [6] Insulation damage; Possible distress in animals that are sensitive to ultraviolet light [7] Electrical components such as transformers, capacitors, electric motors, and generators: Corona can progressively damage the insulation inside these devices, leading to equipment failure. Elastomer items such as O-rings can suffer ...
Syngas is often considered to be a petrochemical; although its production is a core industrial gases technology. Similarly, projects harnessing Landfill gas or biogas, Waste-to-energy schemes, as well as Hydrogen Production all exhibit overlapping technologies. Helium is an industrial gas, even though its source is from natural gas processing.
The "crimp-on valve", used to control the spray in low-pressure aerosol sprays was developed in 1949 by Bronx machine shop proprietor Robert H. Abplanalp. [8] [12] In 1974, Drs. Frank Sherwood Rowland and Mario J. Molina proposed that chlorofluorocarbons, used as propellants in aerosol sprays, contributed to the depletion of Earth's ozone layer ...
