Daniel,
Thank you for your contribution.
You are very fortunate in that you have a supply of gas that has been processed very well. A common characterization practice is often based on a laboratory analysis on a properly extracted sample (per API 14.1) to a sensitivity of 0.1 ppm or at least...
You are absolutely right so the report that SWRI should bear close review as well. It was funded by PRCI (the gas industry) and is under Contract 18-45425-A, between PRCI and Southwest Research Institute released for fional publication January 30, 2008. It compared a C9+ with EOS to other...

The discussion of the proper use of EOS based on GC data is often one that overlooks the obvious - why calculate it using theoretical methods when it can be measured. There are many papers that describe the deficiencies of using EOS for determining this parameter and you can...
A simple calculator can be downloaded at http://www.us.michell-instruments.com/support/downloads/ that will be easy to play with some numbers to see the pressure effect is - the higher you pressurize a gas with water vapor the higher the dew point.
At 25% by volume and at 850°C temperature, the vapor pressure of water is roughly 197 kPa and if the target dew point is 25°C then water in excess of 3.171 kPa will condense (in ideal heat transfer conditions) dropping the water concentration to 0.4% by volume. These are general values but they...
