Finding Work of Compression with a Thermodynamic Chart Hydrogen sulfide is to be compressed from 100°F and atmospheric pressure to SOpsig. The isentropic efficiency is 0.70. A pressure-enthalpy chart is taken from Starling (Fluid Thermodynamic Properties for Light Petroleum Systems, Gulf, Houston, TX, 1973). The work and the complete thermodynamic conditions for the process will be found. 

Numerous equations of state have been proposed and new ones appear regularly. For pure fluids, there are some highly accurate (essentially empirical) equations diet can well represent pure-fluid thermodynamic properties, provided there is a large body of reliable experimental information available for determining the many (typically 15 or more) equation-of-state constants. Unforesnately, lhase equations of stale are of little value for phase-equilibrium calculations in mixtures because it is not clear how to extend such equations to mixtures and because constants for the mixture are not easily determined unless there are many expar-imemal data for the mixture. 

Once you have specified the components present in your simulation, you can now set the fluid package for your simulation. The fluid package is used to calculate the fluid/thermodynamic properties of the components and mixtures in yoiu simulation (such as enthalpy, entropy, density, vapour-liquid equilibriiun etc.). Therefore, it is very important that you select the correct fluid package since this forms the basis for the results returned by your simulation.

Several studies have been devoted to determine the COP and limitations of absorption system operating conditions [21-23]. In order to evaluate the refrigeration absorption system performance, relative to different previously presented configuration, we have developed a numerical program. The calculating procedures of the fluid thermodynamic properties and the performance coefficient were obtained using MAPLE computer tools.

The recently proposed Peng-Robinson equation of state ( 1) incorporates the best features of the Soave (2) treatment of the Redlich-Kwong ( 3) equation into a new model which has some significant advantages over earlier two-parameter equation of state models. The purpose of this contribution is to indicate how the equation performs when it is used for calculating fluid thermodynamic properties for systems of industrial Interest.
