Propanegas behaviour
Propanegas behaviour
(OP)
Friends
I seek for a corelation between the temperature to Density and calorific value of Propane Gas. Is there a fixed chart which can indicate the increase in temperature to decrease in Propane density and other parameters? Can I find out the behaviour of Propane gas at different ambient temperatures?
If some one can forward this detail to me it would be of great help to me.
Thanks

RE: Propanegas behaviour
What range of temperatures are you having to adjust the heating value(s) for?
What units are your heating value in? BTU/scf, BTU/lb?
Pressure also affects the density of propane. You haven't mentioned that so I assume it's not a factor but if it does vary, you need to consider it also.
Finally, what is this correction for? The required accuracy you might need would be a factor of the use, checking a burner capacity would be different than a custody transfer application for example.

As for the pressure, Yes the pressure does varry. However the propane pressure has to go through a series of step down pressure which maintains the final pressure steady.
Bullet pressure is 6 to 7 Kg/Sq. Cm, this is stepped down to 1.8-1.9 Kg/sq. cm which is further stepped down to 45 to 50 inches of water column.
The heat value of Gas 25.85 KWt Hrs/ Cu. Mt. The calorific Value is around 11000 Kcal.
Hope this helps.
