Principle
A stream of gas is fed to a throttling point, where the gas (CO2 or N2) undergoes adiabatic expansion. The differences in temperature established between the two sides of the throttle point are measured at various pressures and the Joule-Thomson coefficients of the gases in question are calculated.
