The primary chemical reaction involves the acetylene disassociating in the presence of oxygen to produce heat, carbon monoxide, and hydrogen gas: C 2 H 2 + O 2 → 2CO + H 2. A secondary reaction follows where the carbon monoxide and hydrogen combine with more oxygen to produce carbon dioxide and water vapor. When the secondary reaction does ...
The justification for using oxy-fuel is to produce a CO 2 rich flue gas ready for sequestration. Oxy-fuel combustion has significant advantages over traditional air-fired plants. Among these are: The mass and volume of the flue gas are reduced by approximately 75%. Because the flue gas volume is reduced, less heat is lost in the flue gas.
A small sample of flue gas is extracted, by means of a pump, into the CEM system via a sample probe.Facilities that combust fossil fuels often use a dilution-extractive probe to dilute the sample with clean, dry air to a ratio typically between 50:1 to 200:1, but usually 100:1.
Pressure in blanketed tanks is maintained by self actuating pressure control valves (PCVs). As liquid is withdrawn from the tank the pressure in the gas space falls. The blanket gas supply valve opens to maintain the pressure. As the tank fills with liquid the pressure rises and a vent gas valve open to vent gas to atmosphere or a vent system. [11]
Oil and gas industry - In the oil and gas industry, oxygen finds application as a means for viscosity improvement and enhancement of oil-and-gas flow properties. Oxygen is also used for boosting production capacity of oil cracking plants, efficiency of high-octane components processing, as well as for the reduction of sulfuric deposits in ...
An oxygen analyser for breathing gas mixtures for diving. The type of oxygen sensor used in most underwater diving applications is the electro-galvanic oxygen sensor, a type of fuel cell, which is sometimes called an oxygen analyser or ppO 2 meter. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and ...

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. The mixture has an indefinite ...
