This work was done to make possible more accurate design calculatioas for processes that require accurate data on the heat capacity of propylene at elevated temperatures and pressures.
The effect of pressure and temperature on the isobaric heat opacity and the heat capacity at constant volume for propylene relative to the ideal gas state is presented. The results cover pressures from 0 to 9,500 PSIA and temperatures from 350°F. to 2240°F.
An equation was derived from the Benedict-Webb-Rubin equation of state. This equation gives the deviation from the ideal gas state of the isobaric heat capacity of propylene for the wide range of pressures and temperatures severed. Graphs and tables relating the deviation of the isobaric heat capacity, the deviation of heat capacity at constant volume, pressure and temperature are included. The results indicate that deviation of the isobaric heat capacity from the ideal gas state caused by the effect of pressure is significantly large and must not be neglected. Small differences in P-V-T data appear to have a pronounced effect on the calculated heat capacity.
A comparison of the calculated data has been made and is included.
