May I ask how to simulate the vaporization of liquid nitrogen using a PRO II heat exchanger?
Thread Content
It is known that the heat exchanger has two flow streams: liquid nitrogen and low-pressure steam. The cold stream – liquid nitrogen: inlet pressure of 101 bar, temperature of -190°C; outlet pressure of 101 bar, temperature of 30°C, flow rate of 2 m3/h； Hot stream – low-pressure steam: inlet 7 bar, 165°C; outlet 1 bar, 60°C. Determine the flow rate of the low-pressure steam Could you please advise on how to use a heat exchanger for calculations? The attachment I uploaded is what I created, but it results in an error and it’s not possible to obtain a solution. Please help.

Chenxh123’s calculation is correct. Could you please point out why there’s an error in my file and how to fix it? Thank you
May I ask chenxh123, how should this example be simulated using ASPEN?
