INDUSTRIAL USES OF EQUATIONS OF STATE A STATE OF THE ART REVIEW
The objective of the the authors of this paper
presentations at this conference~ as understand them, is to document the
state of the art in various areas of thermodynamics. In turn the ultimate objective is to enable academia to grasp the needs of industry, while industry becomes better a~quainted with the new tools developed in the universities. It is recognized that some of these will be ready for use while others are just emerg- ing concepts, hopefully applicable in the future.
Those of us from industry on the week's program have been asked to describe, from the industrial side of the fence, what are the current activities, the developments and the applications of the particular area of phase equilibria or physical proper- ties that has been individually assigned. This paper pertains
to equations of state, especially their application in phase equilibrium predictions. It is not the intention of this key- note speech, nor would it be appropriate, to review all the equations

of state have been assembled. In a second category, the appll- cations in which equations of state are intermixed with thermo- dynamic principles in day-to-day process and design problems and computations are shown. To put it another way, the first llst deals with sharpening the tools; the second list with using the tools.

second reason for developing new equations of state concerns the exceptional power and utility of an equation of state. When combined with appropriate thermodynamic relations, a well-behaved equation can predict with high precision isothermal changes in heat capacity, enthalpy, entropy and fugaci...
