A discussion on a method for accurate calculations of dew points of natural gases in operating gas pipelines covers the commonly used three step method of sampling, analysis, and calculation; direct measurement of dew point; philosophy of proposed method; literature data; the Peng-Robinson EOS; hexanes plus distribution; the Peng-Robinson EOS calculations of PHLC vs. temperature; and two cases in which the uncertainty of a calculated pipeline natural gas dew point temperature will be estimated, i.e., the initial condition when both the gas analysis and the dew point have just been measured and the extended analysis for the hexanes plus has been determined, and a later condition when a new gas analysis will be used to calculate the dew point using the hexanes plus component distribution determined earlier from the measured dew point temperature. This is an abstract of a paper presented at the AGA 2003 Operations Conference (Orlando, FL 4/27-29/2003).
