Consider a liquid feed composed of Ã¢ÂÂbutane, Ã¢ÂÂpentane, Ã¢ÂÂheptane, and Ã¢ÂÂoctane at 50 °C and 1000 kPa. The feed has a flow rate of 10 kmol/hr and contains mole% for each of the four hydrocarbons.

## Details

Fugacity coefficients as well as enthalpy correction functions are calculated using the Peng–Robinson equation of state [1, 2].

Expressions for ideal-gas constant-pressure heat capacities were obtained from Aspen-HYSYS.
