Abstract
The properties of the Joule-Thomson coefficient are discussed in general for pure gases, and the possibility of a nonlinear effect in binary mixtures is analyzed using the First Law of Thermodynamics and some common cubic equations of state. It is shown that although theoretically a binary mixture of gases may exhibit a Joule-Thomson effect different from the molar-weighted mean of the pure-component effects, the possibility of observing a positive difference is very low.
