Answer the following question for a Linde liquefaction process with a nitrogen stream. a. The inlet conditions of a compressor, operating adiabatically and reversibly in a Linde liquefaction process, are 180K and 2.0 MPa. The outlet stream is compressed to a pressure of 8 MPa. What is the outlet temperature of the compressor? b. The outlet stream from the compressor in part a is cooled isobarically and then sent to a flash tank operating at 0.1 MPa. Approximately what temperature must the outlet stream (inlet to the flash tank) be cooled to liquefied 30 % of the flash tank feed stream? You may assume that the flash tank operates adiabatically.

Question

Answer the following question for a Linde liquefaction process with a nitrogen stream.
a. The inlet conditions of a compressor, operating adiabatically and reversibly in a Linde
liquefaction process, are 180K and 2.0 MPa. The outlet stream is compressed to a pressure of 8 MPa. What is the outlet temperature of the compressor?
b. The outlet stream from the compressor in part a is cooled isobarically and then sent to a
flash tank operating at 0.1 MPa. Approximately what temperature must the outlet stream
(inlet to the flash tank) be cooled to liquefied 30 % of the flash tank feed stream? You
may assume that the flash tank operates adiabatically.
