Joule Thomson Effect

Joule Thomson Effect

Joule Thomson Effect

(OP)
Is joule thomson cooling effect much effective (more heat is dissipated) if cooler feed is applied?

RE: Joule Thomson Effect

More heat is dissipated....

Like if I start with 20C and it cools down to 10C. (10C differential)

While if I start with 15C and it cools down to 0C. (15C differential)

Much more heat is dissipated if I started with the upstream with lower temperature.

RE: Joule Thomson Effect

This is basic thermodynamics. You should be carefull using an answer for any design since "results may vary". However, as a rule of thumb NG will see a ½ºC dT pr. bar pressure drop disregaring initial T in the P range 0-100 bar. Condensation will e.g. change this.

Best regards

Morten
