Calculating the Dynamic Viscosity of Paraffins Using the Lee-Kesler Equation

摘要

A model for calculating the viscosity of individual paraffins that constitute the major part of the products of the Fischer-Tropsch synthesis is developed on the basis of the fluctuation hypothesis of the formation of vacancies in the liquid phase. All of the thermodynamic parameters of a substance and the energy barrier of the formation of vacancies are calculated using the Lee-Kesler equation of state. The results of the calculations of the viscosity of heavy paraffins are compared with the experimental data from published works.
