Hi All,

From the fuel gas system HYSYS model I developed, I noticed that the HC dew point of the gas @ stream condition is 62.22 deg.F. The stream condition are temperature @62.23 deg.F and pressure @ 250 psig. The fluid is a fuel gas to be supplied to a GTG.
1) Would this close HC dew point temperature to stream temperature affect the property of the fuel gas to the GTG?
2) Should I consider the installation of a heater to increase the flow temperature when the FG condition required by the GTG is within the range of 45.8 - 48 deg.F and 242 - 250 psig?</p>

Hi Asade,

you need to see the lowest temperature in the plant area,
at the stream conditions (62.23 degF; 250 psig) there is no problem, but there will be liquid formation at the lower temperature caused by environment.
installing heater or heat trace the line is common for fuel gas supply to the users (boiler, etc)
