for a natural gas mixture with large fractions of heavy components (C6+) I get different (> 8 K) results with the Peng Robinson and the Extended Peng Robinson models available in Prode,
a laboratory chilled mirror returns intermediate values (but close to Extended Peng Robinson),
Prode is connected to the DCS and calculated values are stored (dew point being a contractual specification).

It seems that heavy fractions have a large influence on dew point , Prode allows to adopt different rules to estimate C6+ and heavier fractions (50%, 50% etc.)  
there is a discussion in GPA but a detailed procedure is not given,
can you suggest a step by step procedure ?

I guess Prode is connected to a GC (for gas analysis),

if that is the case you can adopt the procedure discussed in Prode Industrial Interface manual,

you can split to predefined fractions of C6, C7, C8, C9 or heavier components,

I don't know of a specific procedure to identify the different fractions,

have you considered to use Excel (solver) Optimizer to regress the fractions to a table of measured values ?

That could be a solution but others are available...
