“…A summary of the coefficients used with the B-W-R equation is presented in Table AIII. The coefficients of hydrogen are those developed by Motard and Organick (1960) except for the values of y. The values shown for 7 are an extrapolation of Motard and Organick's values at lower temperatures.…”

The fugacity of hydrogen in mixtures with ammonia and propane was determined directly from a physical equilibrium method using a palladium-silver semipermeable membrane, at temperatures between 71 and 121°C (160 and 250°F) and pressures up to 102 atm (1500 psi). Measurements at low hydrogen concentrations were emphasized in order to investigate the region of higher nonideality of the gas mixtures. The data obtained were used to evaluate the predictive properties of a number of equations of state. These included both the original and a modified Redlich-Kwong, Black, Martin-Hou, Benedict-Webb-Rubin, and the virial equations.

The vapor‐liquid equilibrium of the hydrogen—n‐butane system at elevated pressures

The vapor‐liquid equilibrium of the hydrogen–n–butane system was studied at temperatures between 54° and 121°C and at pressures up to 167 atm. The fugacity of hydrogen in the vapor phase was measured directly by using a palladium‐silver semipermeable membrane, whereas p‐T‐x‐y data were obtained in a conventional manner.Henry's constants for hydrogen in n‐butane were obtained from the experimental fugacity data without making any assumptions about the vapor phase. Constant‐pressure, liquid‐phase activity coefficients for both hydrogen and n‐butane were calculated and correlated by using a modified van Laar equation.

“…Thus the data were inconsistent, a very controversial conclusion. The relevance of the situation was that another attempt to model the system was judged as flawed because of discrepancies with these data. The analysis was buried at the end of a theoretical article about the Kihara intermolecular potential model …”

This Founders Tribute issue honors John Prausnitz as an exceptional intellectual leader, scholar, and educator and summarizes his impact on chemical engineering. John's early vision of connecting fundamental molecular theory to practical thermodynamic applications with Molecular Thermodynamics was an essential element in our profession's paradigm shift from empiricism to engineering science. John's writings and lectures have transformed our core knowledge and guided its utilization into areas well outside traditional engineering bounds. Further, he has vigorously advocated for technology to be considered in the context of all of life and as a human enterprise. Finally, John's personal interactions across generations and disciplines have inspired the personal and professional development of a vast community of students, coworkers, and colleagues. In countless ways, John Prausnitz has influenced the contemporary foundation and functioning of chemical engineering and of realms beyond. © 2015 American Institute of Chemical Engineers AIChE J, 61: 2675–2688, 2015
