Density of Natural Gases

Abstract

DENSITY data are reported on 16 saturated is the use of the ideal gas law corrected by a hydrocarbon vapors at pressures ranging from compressibility factor. The method pro-1000 to 8220 lb. per sq. in. and at temperatures posed by K ay 7 of correlating compresranging from 35° to 250°F. These data have sibility factors for gaseous mixtures on been used to extend the compressibility-factor chart for natural gases up to !O,ooo lb. per pseudocritical properties 5 appears to be sq. in.

Revisiting the applications of drainage capillary pressure curves in water-wet hydrocarbon systems

“…The interfacial tension was calculated using equations of Sutton P. R. [10]. The necessary PVT and compositional data of formation water and dry gas were available from the laboratory and all equations were chosen from widely used literatures and authors [23,[40][41][42][43][44][45][46][47], so all of the necessary data (absolute density at reservoir conditions, pseudo reduced and pseudo critical pressures and temperature, formation volume factor for gas and water, z-factor) became available. The dataset, measured and calculated, used in capillary pressure conversion is shown in Table 4.…”

Worker safety in a mature carbon capture and storage industry in the United States based upon analog industry experience

“…Standard condition is 60 • F and 1 atm. k From volume assuming 0.7-gravity (non associated) gas, the density of which is 100 kg/m 3 at the reference reservoir conditions (Standing and Katz, 1942). l The mass is likely 5-10% higher due to salinity, but the average salinity, temperature and pressure for the produced waters was not reported (Clark and Veil, 2009), so the mass conversion used the density of fresh water.…”

Static Behaviour of Natural Gas and its Flow in Pipes

“…The gas deviation factor (z) can be obtained from the chart of Standing and Katz (1942). The Standing and Katz chart has been curve fitted by many researchers.…”

“…In order to find a solution to the differential equation for downhill flow (as presented in equation (29) and (32) we need equations or charts that can provide values of the variables z and f. The widely accepted chart for the values of the gas deviation factor (z) is that of Standing and Katz (1942). The chart has been curve fitted by some researchers.…”
