Natural Gas moisture

Extracted from "Equilibrium Moisture Content of Natural Gases" by R.F.Bukacek Research Bulletin 8, Institute of Gas Technology, 1955.See: ASTM D1142-90 Water Vapor Content of Gaseous Fuels --------------> W = w x 10E6 x(Pb/P x T/Tb) by Measurement of Dew-Point Temperature. where W = water content, lb/MMSCF at Pb, Tb.

w = water content, lb/ft³, at dewpoint (reciprical of the specific volume of saturated vapour Table 1 of ASTM D1142-95)Pb = pressure base of gas measurement, psia (e.g. 14.7psia)

W = A / P + B P = pressure of dewpoint measurement, psiawhere W = water content of sweet natural gas, lb/MMSCF. t = observed water dewpoint temperature, T°F P = pressure, psia. T = Rankine observed water dewpoint temperature, t+460 A,B = functions of dewpoint temperature. tb = base temperature, t°F (e.g. 60°F)

Tb = Rankine base temperature, tb+460log A = 10.930 - 3002.8 / (T + 378)log B = 6.748 - 3113.9 / (T + 460)

Ideal gas convesions. (Du Pont)

Definitions.Dew point is the temperature at which water begins to condense out ie the gas is saturated.Parts per million by volume (ppmv) is the ratio of water vapour pressure to total gas pressure.

Conversion Formulasmg/L = ppmv x 8.04E-4ppmw = ppmv x 18 / M where M = molecular weight of the gas.lb/mmcuft = ppmv x 4.76E-2

0.775488 Compressibility factor at P & T given.Z=F1*(1/VAL4+(F2*F3))+F4+F5

Note: Since Z is a function of P & T to determine the volume change with pressure it is necessary to integrate Z with respect to P and T.
