Thermodynamics for Chemical Engineers

Abstract

This textbook covers the thermodynamics needed by chemical engineers both in their engineering and in their chemistry; it is intended for use in all undergraduate and some graduate-level courses. The authors emphasize a rigorous yet concise presentation of the fundamental chemical concepts governing the behavior of single and multicomponent mixtures, including phase and chemical equilibria. In the application of these concepts, consideration is given to the presentation of experimentally measured thermodynamic properties, and to their prediction for real fluids and their mixtures using methods founded on statistical mechanics. Several applications involving the transfer of heat and work that are of special importance to chemical engineers are studied in detail to show the use of thermodynamics in improving performance. The book is written in SI units and contains worked examples, exercises, and problems.

Developing intermolecular‐potential models for use with the SAFT‐VRMie equation of state

“…Fluid‐phase coexistence requires the conditions of thermal, mechanical, and chemical equilibrium, which can be solved for a pure component by ensuring that the temperature, pressure, and chemical potential are equal in each phase. Having specified the explicit form of the Helmholtz free energy, the pressure , chemical potential , and other thermodynamic properties can be obtained algebraically from the standard thermodynamic relations . As well as the fluid‐phase equilibrium properties, in our current work, we assess the adequacy of the SAFT‐VR Mie EOS in describing second‐order derivative properties including the isobaric heat capacity c p , the speed of sound u , and the Joule–Thomson coefficient .…”

Carbon capture and storage: Fundamental thermodynamics and current technology

“…With g being the ratio of the molar specific heat at constant pressure C P to the molar specific heat at constant volume C V , and p 1 , p 2 being the initial and final pressure of the gas (Bett et al, 1975). The Carnot expression for the minimum work required for liquefaction by refrigeration is given by…”
