What is the density of natural gas
Natural gasNatural gas refers to the animal and plant body by biological and chemical and geological change, generation and transfer in different conditions, and under certain pressure of the reservoir, burial quality of combustible gases in different depth in the stratum. The main ingredient is saturated hydrocarbons, including methane, ethane, propane, butane, pentane content is not much, also contains a small amount of non hydrocarbon gases, such as carbon monoxide, carbon dioxide, nitrogen, hydrogen, hydrogen sulfide, water vapour and trace inert gas such as helium and argon.
4 calorific valueCalorific value refers to the standard 1 cubic meters of a certain amount of gas completely burned out of the heat, belonging to the characteristics of the material, the symbol is Q, the unit is the joule per cubic meter, the symbol is J/m3. Calorific value of high calorific value and low calorific value two.High calorific value refers to a standard cubic meters of gas after the complete combustion of the flue gas is cooled to the original temperature, and the water vapor in the condensed water discharged from the state of heat.Low calorific value refers to a standard cubic meters of gas after the complete combustion of the flue gas is cooled to the original temperature, but the water vapor in the flue gas is still the state of the heat released. The high calorific value of gas is larger than its low calorific value, and the difference is the latent heat of vaporization. Because natural gas is a mixture of gases, different components and different proportions of the components will have different calorific value,
1 density and relative densityUnder normal temperature and atmospheric pressure, the density of methane is 0.7174kg/m3, the relative density is 0.5548.The density of natural gas is generally 0.75 kg/m3 ~ 0.8kg/m3, the relative density is generally from 0.58 to 0.62.2 ignition temperatureThe ignition temperature of methane is 540.3 combustion temperatureThe theoretical combustion temperature of methane is 1970.The theoretical combustion temperature of natural gas can reach 2030.
Under normal temperature and atmospheric pressure, the density of methane is 0.7174kg/m3, the relative density is 0.5548.The density of natural gas is generally 0.75 kg/m3 ~ 0.8kg/m3, the relative density is generally from 0.58 to 0.62.The density of natural gas is related to the temperature, pressure and the composition of natural gas. Under normal circumstances, the density of the natural gas varies from 0.55 to 0.90kg / m3.The relative density of natural gas is the ratio of the density of natural gas to the density of air under the standard state (0, 101.325kPa)
