thermodynamic evaluation of the kalina split cycle
Modeling the High-Pressure Ammonia−Water System with WATAM
The Kalina power cycle uses an ammonia−water mixture as the working fluid in the 283−866 K temperature range and at pressures up to 22 MPa. Modeling of these cycles typically accomplished with a process simulator requires accurate descriptions of the phase behavior of this binary. Therefore 58 previously published Pxy isotherms in the 203−618 K temperature range were used to evaluate
