In 2004, we started to develop a group contribution method aimed at estimating the temperature-dependent binary interaction parameters (k ij (T)) for the widely used Peng−Robinson equation of state (EOS). This model was called PPR78 (predictive 1978, Peng Robinson EOS), because it relies on the Peng−Robinson EOS as published by Peng and Robinson in 1978 and because the addition of a group contribution method to estimate the k ij value makes it predictive. In our previous papers, 12 groups were defined: CH3, CH2, CH, C, CH4 (methane), C2H6 (ethane), CHaro, Caro, Cfused aromatic rings, CH2,cyclic, CHcyclic = Ccyclic, and CO2. Thus, it was possible to estimate the k ij value for any mixture that contains alkanes, aromatics, naphthenes, and CO2, regardless of the temperature. In this study, the PPR78 model is extended to systems that contain nitrogen. To do so, the group N2 was added.

In 1958 the Bureau of Mines Helium Activity proposed a policy for the conservation of helium, vitally needed in the nation's atomic energy and space programs. During the summer of 1960 a helium conservation bill passed both houses of Congress and was signed by the President on September 13, 1960. The resulting legislation, which becomes effective March 1, 1961, calls for the construction of additional plants, either by private companies or the U.S. Bureau of Mines, to produce crude helium from natural gases now going to fuel markets. This impure helium will be
