AmsterCHEM REFPROP CAPE-OPEN

REFPROP is a program that uses equations for the thermodynamic and transport properties to calculate the state points of the fluid or mixture. These equations are the most accurate equations available world wide. Their high accuracy is obtained through many coefficients in the equations, and thus the calculation speed will be slower than other equations such as Peng-Robinson cubic equations. The equations are generally valid over the entire vapor and liquid regions of the fluid, including super-critical states; the upper temperature limit is usually near the point of decomposition of the fluid, and the upper pressure (or density) limit is defined by the melting line of the substance.
