Discussion on the issues related to ammonia removal settings of the device?
Thread Content
As the title suggests, for systems that use ammonia refrigeration for low-temperature purification, should ammonia return pipelines be considered for both the low-temperature section and the refrigeration station? How should the destination for ammonia removal be determined? Thank you!
An ammonia rejection line should be installed, leading to the external liquid ammonia storage tank.
How is liquid ammonia generated in low-temperature devices, and how is ammonia removed from them?
After the plant is shut down, the ammonia with low methane content is discharged through the ammonia cooler into the liquid ammonia discharge tank, and then pumped to the refrigeration station. Gaseous ammonia is removed by nitrogen displacement; if it is to be introduced into towers or tanks, water washing is required
