Appropriate Placement of Compressors and Expanders

Apr 4, 2012
Truls Gundersen
The term “Appropriate Placement” was introduced in Pinch Analysis during the 1980s to indicate how special unit operations should be correctly integrated with the background process to ensure maximum energy savings. Pinch Analysis has provided guidelines for the design of heat exchanger networks as...

Alan Rossiter

This webinar introduces the basic principles and tools of pinch analysis and shows how they can be applied in real-world applications.

Thermodynamics for the Practicing Engineer

June, 2009
Thermodynamics for the Practicing Engineer, as the title suggests, is written for all practicing engineers and anyone studying to become one. Its focus therefore is on applications of thermodynamics, addressing both technical and pragmatic problems in the field. Readers are provided a solid base in...

Success and Prospects in Thermodynamics

Nov 16, 2008
Peter T Cummings
Accurate thermodynamic models are essential to any chemical engineering endeavor. In this presentation, Cummings reviews some of the more important developments in the history of thermodynamics; from Gibbs and van der Waals in the nineteenth century, to the statistical mechanicians of the twentieth...

A Simple Approach to Vapor Pressure Prediction

January
2007
Reactions and Separations
Andrew J. DeDoes, Matthew D. Goetz, Michael J. Misovich
This method reproduces the vapor pressure predictions of the Soave-Redlich-Kwong and Peng-Robinson equation of state with a simple Antoine equation that uses constants derived from critical properties and the acentric factor.
