Linde process of gas liquefaction employs__________________?
Correct answer: B. Adiabatic expansion through a throttle valve (Joule-Thomson expansion)
- A. Exchange of heat with colder stream
- B. Adiabatic expansion through a throttle valve (Joule-Thomson expansion)
- C. Adiabatic expansion against a piston or in a turbine
- D. Merely compressing the gas beyond its critical pressure
Explanation
The Linde process cools compressed gas by regenerative heat exchange and Joule-Thomson throttling, which is approximately isenthalpic rather than turbine expansion. Option b identifies the characteristic throttling step.
