How to convert 3MPA, -4°C liquid ammonia into 0MPa, -33°C gaseous ammonia, with a liquid ammonia flow rate of 55 t/h
The operation of feeding produced liquid ammonia into an atmospheric-pressure liquid ammonia tank
No, it seems there is a refrigeration unit that circulates coolant to maintain the temperature
If necessary, you can go to Baidu to read this article; registration is required
You can refer to this post; everyone, please help me review the flowchart for the liquid ammonia plant: https://bbs.hcbbs.com/thread-1539194-1-1.html (Source: Haichuan Chemical Industry Forum)
Does the landlord want gaseous ammonia? This requires a vaporizer, and the cooling capacity can also be reused. After being depressurized, high-pressure liquid ammonia enters the vaporizer; heat is supplied by circulating chilled water. The heated ammonia then goes into the separator, while the liquid ammonia returns to continue vaporizing. The gaseous ammonia is sent to the end users
"3MPA, -4℃ liquid ammonia. I thought liquid ammonia didn’t have such a high vapor pressure; is pressure applied using a pump? This liquid ammonia can be heated and vaporized through a vaporizer, and a considerable amount of it is available for heat recovery. This is a simple issue that falls under routine operations; however, dealing with such a large volume of liquid ammonia isn’t something an amateur can handle – professional design is required
This should be the process in an ammonia synthesis plant; liquid ammonia is stored in tanks to maintain a low temperature. I’ve seen several documents indicating this parameter, and it seems to be a requirement for pipeline transportation
