NettetJoule Thomson Effect Definition. When a real gas is subjected to adiabatic expansion process, where no heat is exchanged with the surroundings, it looses its temperature. This cooling effect of gas expansion is known as the 'Joule Thomsone effect'. This is even applicable to real gases when the Z factor or compressibility factor is used. So ... NettetA frozen valve can lead to production downtime and frustration. Due to the Joule-Thomson Effect, if enough pressure is reduced across a valve, the condensation can freeze, causing significant problems for your production. Our recommendation to prevent this is to use a catalytic heater on the valve b...
