Dear all,

 

We want to calculate the dew point temperature© of water in natural gas.

 

We have the following details

1) Molecular wt of gas = 17.72

2) Water vapour = 110 ppm(v)

3) Pipeline pressure = 70 kg/cm2 g

4) Pipeline Temperature = 16.63 DegC

 

Can you help me with the formula to use?

breizh has given a good advice, at cheresources you'll find several threads discussing this topic,

 

anyway, when composition is not available you may consider the graphical methods discussed in GPA,

here you may find a copy of McKetta , Wehe chart,

differently (composition available) accurate procedures are available based on estimates of fugacities of different components in the mixture,
for a numerical example see post 13# in thread
