Abstract
For one of cubic equations of state, the Redlich-Kwong, the inverse curve, which characterizes a change in a sign of the Joule-Thomson coefficient, has been constructed. The range of reduced pressure and temperature corresponds to the values intrinsic of technological changes in production and transport systems of natural gas.
