Abstract
A method for converting a retrograde substance from a liquid to a gaseous state comprising bringing the substance to a defined initial state of pressure and volume, and relaxing to a defined final state. The defined states correspond to regions on the pressure-volume diagram of the substance, the initial state lying to the lower volume side of a boundary defined by the branch of the critical isentrope lying to the greater pressure side of the critical point, and by the stability limit of the substance. The final state lies to the greater volume side of this boundary.
