What should be done if brine becomes saturated with ammonia in a small compression plant?

Choosing to run the brine to the sewer and make a new batch is a prudent action when the brine becomes saturated with ammonia in a small compression plant. This saturation can lead to inefficiencies and potential operational issues, such as equipment damage or failures in the refrigeration system if the ammonia concentration is too high.

By discarding the saturated brine, you remove the problematic ammonia and avoid risks associated with its accumulation. Furthermore, creating a new batch of brine allows for maintaining optimal performance of the cooling and refrigeration systems, ensuring that they operate efficiently and safely. This proactive approach minimizes the chance of operational disruptions and protects equipment integrity.

In contrast, other options may either not address the root problem or could lead to further complications. For instance, running the brine through a cooling tower and treating it with lime might not effectively resolve the ammonia saturation issue, while simply treating the brine with lime alone would not be sufficient to eliminate the excess ammonia. Ignoring the issue altogether would likely exacerbate the problem, leading to more significant operational and safety concerns down the line.
