A critical evaluation and modification of the available methods for the estimation of critical properties of pure hydrocarbons was undertaken to determine the most accurate method which has general applicability with minimum input data. As a result of the study, the method of Nokay as modified by the authors is recommended for the estimation of critical temperature while the method of Reidel is the best general method for critical volume. For critical pressure the Lydersen method is preferred for saturated hydrocarbons, while the method of Forman and Thodos is somewhat better for unsaturated hydrocarbons.
