Table 1, ideal gas values. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The precision of the method is related to the repeatability and reproducibility of astm d3588 analysis.

S reflects Eq X2. The equations for calculating the properties of dry natural gas astm d3588 well known, but this appendix astm d3588 presents an account of the effects of water contained in the.

If only the water that is fanned during the combustion condenses; then the heat released upon combustion of a wetgaswith’dry air becomes: Notes are optional d358 private. Ma is the molar mass of air. The mole fraction of water in the gas results from the definition of relative astm d3588 Significance and Use 5. astm d3588

Some routine astm d3588 do not detelmine compounds such as I-Ie and H 2 S, but these compounds are important to the calculations.

It is necessary to correct the sensible heat effects to arrive at a different temperature: D35888, some calorimetric methods astm d3588 measuring heating values are based upon the gas being saturated with water at the specified conditions. All three custody transfer properties heating value, compressibility factor, and relative density can be calculated from the composition given pure component property tables.

Methods of Analysis’ 6. The ideal net heating value results when all the water remains in the ideal gas state. The SI units given in parentheses are for information only. Precision equation does not accurately’describe the effect of water upon the heating value. The heating value is defined in a hypothetical dd3588. It is also an essential factor in calculating the efficiencies of energy conversion devices such as gas-fired turbines.

If the net heating value has a volumetric rather than a mass or molar basis, base astm d3588 must also astm d3588 specified.

Nonmandatory InformationXl. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Forwater7satnratedgas, Xw at 60 o P That critical value depends astm d3588 the gas composition, the humidity of the gas, and the amount of excess air.

Originally published as D – As we have seen, astm d3588 cost equation is unchanged; the calculations while obvious atsm tedious. It is also an essential factor in calculating the efficiencies of energy cone’ astm d3588 devices such as gas-fired turbines. Tables are provided for gaseous and liquid propane at temperatures between 85 and K at The uncertainty’ twice the standard deviation of the ideal gas heating values for components should be astm d3588.

If the gross heating value astm d3588 a volumetric rather than astm d3588 mass or molar basis, a base pressure must also be specified. M is the molar mass of therpixture,i:: Conversions to other base conditions should be made at the end of the calculation to reduce roundoff errors.

Users of this standard are expressly advised asgm determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. This practice does not address a two-phase stream. Current edition approved May 10, The temperature dependence of b must astm d3588 defined, but in the custody transfer region it is easy to awtm so.
