Unlock the power of Exergy Analyses Quickly and Easily

Exergy is a fascinating topic. Using thermodynamic principles, exergy is a metric that measures both the quality and quantity of an energy source. This metric is extremely useful in chemical, mechanical, process, and many other kinds of industrial engineering fields. A practitioner can use exergy as part of a systems analysis to compute useful metrics for an energy system, such as its exergy efficiency, exergy destruction, and exergy flows.

This information is useful to understand where bottlenecks in a process might be, why a process might not be operating as efficiently as possible, and what areas to target for improvement. It is useful also for big picture decision-making, such as selecting the best processes, fuels, or unit operations for the task at hand, or whether to green light a process in the first place.

We Did the Hard Work so You Don’t Have To

That’s where Exergy Tables comes in. Exergy Tables gives you an easy way to apply this powerful tool without having worry about detailed thermodynamic theory. We have created a useful tool for the practicing engineer that makes exergy analysis much easier. The first chapter explains exergy in simple, plain language, so you can get started quickly. The second chapter provides an easy-to-follow discussion of the theory behind it and how numbers are calculated, in case you want to compute some of your own. The third chapter shows examples for how you can use Exergy Tables in your own analysis.

But it’s the rest of the book that is most useful—seven chapters of lookup tables and reference figures that contain pre-calculated exergy values for thousands of chemicals, fuels, mixtures, and process streams commonly found in the industry. We’ve defined the reference conditions, collected the necessary data, applied the theory, and compiled the results into easy-to-use tables and figures, so you can get right to the good stuff—applying exergy analysis to gain important insights into your process, investigate options, and make meaningful improvements

Pressure-Enthalpy-Exergy Diagrams

Exergy Tables contains convenient PHE diagrams not found anywhere else. Quickly find the thermo-mechanical exergy of pure chemical fluids depending on their temperature, phase, vapor fraction, enthalpy, or entropy. For example, if you know the temperature and pressure of your gas, liquid, or supercritical fluid, just plot the point on the chart and read off the thermo-mechanical exergy. No calculus, equations of state, or complex thermodynamics needed! We did that all for you!

Chemical and Thermo-mechanical Exergy Data Tables

Chemical exergy can be incredibly hard to calculate, especially for mixtures. Don’t worry though, we’ve got you covered. We’ve calculated the chemical exergies for thousands of chemicals, fuel mixtures, and common industrial process streams for you. The calculations all use a consistent set of reference conditions using the latest thermodynamic theories, so that you can easily combine numbers from throughout the book together in the same analysis. (If you cherry pick numbers from one source to the next that were computed with different reference conditions, you’ll get the wrong answers!). Just look up the chemical or mixture you care about, find the chemical exergy, and get right to the good stuff!
