A thoroughly revised edition of the "must have" chemical engineering reference This go-to chemical engineering guide provides you with a single source for up-to-date physical data, chemical data, and predictive methods. Fully updated for the latest advances, the book contains hands-on estimation methods for extrapolating and interpolating. New content includes advanced EOSs with correlated and predicted parameters (e.g. SAFT implementations), advanced computational methods, (e.g. molecular simulation), quantum density functional theory (e.g. LCC) and semi-empirical combinations (e.g. COSMO-RS implementations and SPEADMD). This broad review and objective evaluation of wide-ranging methods is essential to progress in the field of thermophysical property prediction and to advancing the fundamentals of chemical process and product design. The Properties of Gases and Liquids, Sixth Edition provides the latest curated data on over 480 compounds and includes a special section devoted to the interpretation of uncertainty in physical property estimation. Supplemental materials and compilation methods are less committed to hand calculations than in previous editions. Chapter-by-chapter sample calculations are provided throughout. Refreshed throughout to include the latest data and methods Includes computer codes that reproduce the computations in the book Written by a team of recognized chemical engineering experts
