C6+ characterization for natural gas 9

[gaswell]

on our lines we have gas chromatograps measuring C1-C6 , the software calculates Cricondentherm, Wobbe, Dew Points etc. splitting C6+ in two fractions (according AGA method), our client (with their simulator and compositions from laboratory analysis) calculates different results (6-10 F in dew points), a chilled mirror returns intermediate values but closer to client's results. We had a long discussion about the procedure to use and there was no agreement, which is the usual practice ?

You use a commercial AC unit to chill the gas.

[PaoloPemi]

no issues,
when practicable installing a chilling system offers several advantages
