Nitrogen Carbon dioxide

Composition - which describes the proportion of hydrocarbon components (C, - Cj+) (which determine the fluid properties), and how many non-hydrocarbon substances (e.g. nitrogen, carbon dioxide and hydrogen sulphide) are present.

INERTING Depression of the flammable limits of a flammable gas/vapour-air mixture by the addition of an inert gas, e.g. nitrogen, carbon dioxide, or similar mixtures, to render it nonflammable.

K-factors for vapor-liquid equilibrium ratios are usually associated with various hydrocarbons and some common impurities as nitrogen, carbon dioxide, and hydrogen sulfide [48]. The K-factor is the equilibrium ratio of the mole fraction of a component in the vapor phase divided by the mole fraction of the same component in the liquid phase. K is generally considered a function of the mixture composition in which a specific component occurs, plus the temperature and pressure of the system at equilibrium. 

Dissolved gases (oxygen, nitrogen, carbon dioxide, ammonia, sulphurous gases).

Oxygen, nitrogen, carbon dioxide, ammonia, hydrogen sulfide, sulfur dioxide, and other contaminant gases are generally present to some degree in all steam and condensate systems. 

To illustrate this thermodynamic consistency test, Figs. 15, 16, and 17 show plots of the appropriate functions needed to calculate Areas I, II, and III, respectively, for the nitrogen-carbon dioxide system at 0°C the data are taken from Muirbrook (M5). Fugacity coffiecients were calculated with the modified Redlich-Kwong equation (R4). 

The most important gas on the planet is the atmosphere, a thin layer of gas held by gravity to the surface of the Earth. Half the mass of the atmosphere lies below an altitude of 5.5 km. If we were to look from a point where the Earth appears to be the size of a basketball, the atmosphere would appear to be only 1 mm thick (Fig. 4.1). Yet this delicate layer is vital to life it shields us from harmful radiation and supplies substances needed for life, such as oxygen, nitrogen, carbon dioxide, and water.

The combustion of butane is preventable by adding nitrogen, carbon dioxide, or even water vapor until the oxygen concentration is below 12.4%. The addition of water, however, is not recommended because any condition that condenses water would move the oxygen concentration back into the flammable region. 

Recently, the gas types nitrogen, carbon dioxide and helium were shown to have no influence on the reaction rate at 226 °C over 6h [32], Similarly, no difference between nitrogen and carbon dioxide at 210 °C over 24 h was observed [41], An early study [31] did show that the gas type influenced the reaction rate, but it has since been suggested that the different heat capacities and thermal conductivities of the gases affected the experimental temperatures [32],... 

Although comparisons for the steam-methane system have been presented, similar trends were noted for the other binary systems previously published by Wormald, namely mixtures of steam with nitrogen, carbon dioxide, n-hexane, and benzene.
