The density is usually represented in units of lbm/ft3. density of compressed natural gas is equal to 128.2 kg/m³. E    1 kg = 0.8299 m3. The natural gas is non ideal and thus, it follows a real gas law. per sq. Is Natural Gas Heavier than Air - Relative Density of Natural Gas Density of natural gas is not heavier than air. Reservoir gas density is termed as the ratio of mass of gas to the reservoir volume. The fact that LNG takes up much less space than natural gas is its key advantage. γ g = 0.7; H 2 S = 7%; CO 2 = 10%; p = 2,010 psia; T = 75°F. copyright, 1942 and 1943, by the american institute of mining and metallurgical engineers (incorporated) density of natural gases by marshall b. standing* and donald l. katz,*… in. The surrounding environment will gain this amount of energy. Google use cookies for serving our ads and handling visitor statistics. When natural gas is produced from different locations and reservoirs, it tends to have different compositions, i.e., its composition is not standardized, thus, a standard density value of natural gas is not possible to determine. Natural gas withdrawn from natural gas or crude oil wells is called wet natural gas because, along with methane, it usually contains NGL—ethane, propane, butanes, and pentanes—and water vapor. Density of natural gas (methane) is lighter than air, as it is less dense (lighter) than air, with the relative density of natural gas being 0.5537 to 1.
