Chemical Engineering Thermodynamics

Which one is true for a throttling process?

  • A. A gas may have more than one inversion temperatures
  • B. The inversion temperature is different for different gases
  • C. The inversion temperature is same for all gases
  • D. The inversion temperature is the temperature at which Joule-Thomson co-efficient is infinity
Answer: Option B.

Different gases will have different inversion temperatures usually the hydrogen and helium will have very low maximum inversion temperatures so, cooling by using throttling for these gases is slightly difficult.
