Abstract

A method is disclosed which avoids the formation of droplets by condensation of vapors during the expansion of a highly compressed gas through a critical orifice. The pressure drop is distributed over a sufficient number of critical orifices so as to limit the temperature drop insufficient to initiate droplet formation. One application of the method is pressure reduction of cylinder gases without droplet formation.
