Why is the pressure maintained at 0.3 MPa after nitrogen purging in the synthetic ammonia refrigeration cycle? Asked a fellow traveler!
The original poster didn’t make it clear – are there any follow-up tasks you need to carry out?
The operating pressure of the ammonia cooler in the refrigeration unit is 0.3 MPa; the equipment must not be exposed to excessive pressure
1. There is no fixed standard for this holding pressure; it only needs to be determined with considerations for safety and energy savings. 2. What is your cooling water pressure without it? Is it to prevent leaks inside the heat exchanger, so that cooling water does not enter the system and oxidize the catalyst?
