If the gross heating value has a volumetric rather than a mass or molar basis, a base astm d3588 must also astm d3588 specified. The asmt value is defined in a hypothetical state. The practice applies when quality is expressed as either the lot average for a given property, or as the lot fraction not conforming to presc The method based upon Eq lLhas been adopted for this practice.

That critical value depends upon the gas composition, the humidity of the gas, and the amount of excess air. It is obvious that all of the reaction water actually cannot condense because in a situation in which both gas and air are dry some of the astm d3588 water astm d3588 the product gases and the remainder condenses.

It is also an essential astm d3588 in calculating the efficiencies of energy conversion devices such as gas-fired turbines. Therefore, the heating value is used as a parameter for determining the price of gas in custody transfer. The precision of the method is related to the repeatability and reproducibility of the analysis. Ma is the molar mass of air.

The quantity Hw id – Aatm l is the ideal enthalpy of asttm for water. This practice does not address a two-phase stream. D – 98 Standard Practice for Calculating Heat Value, Compressibility Factor, astm d3588 Relative Density of Gaseous Fuels 1 This standard is issued under the fixed designation D ; the nwnber immediately astm d3588 the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

C2He C3 Ha C. Eq16 is’adequate for custody transfer applications as ‘a matter ofdefini. S reflects Eq X2. Originally published as D – An example appears in Table astm d3588. The equations for calculating the properties of dry natural gas are well known, but this appendix also presents an account of the effects of water contained in the. This method may also provide information astm d3588 hydrogen sulfide and elemental sulfur that may be present in these sample types.

The values for the pure gases appear in GPA Standardwhich is revised annually. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are satm astm d3588 own responsibility. Notes are optional and astm d3588. This is simply a matter of evaluating astm d3588 integral: Aastm heating value is, therefore,’ an ideal gas property that can be calculated unambiguously from tables of pure component values and it has no pressure dependence.
