AN EFFICIENT METHOD FOR ESTIMATION OF HYDROCARBONS VAPORIZATION ENTHALPY ACCORDING TO THE BOILING TEMPERATURE AND CRITICAL POINTS

The heat of vaporization of a pure liquid at its normal boiling temperature is a very important property in many chemical processes. In this work, a newempirical method was developed to predict vaporization enthalpy of pure hydrocarbons. This equation is a function of boiling temperature, reducedtemperature, and critical pressure. The presented model is simple to use and provides an improvement over the existing equations for more than 300 purehydrocarbons in wide boiling range. The results show that the proposed correlation is more accurate than the literature methods for pure hydrocarbons in wide boiling range
