Who has experience storing 30% ammonia solution? Let’s share our experiences. The higher the concentration of ammonia solution, the more volatile it is. Should an ammonia storage tank be designed as a pressure vessel? If so, a safety valve must be installed. Where should the outlet of the safety valve lead? `
30% ammonia solution suffers from excessive pressure loss at atmospheric pressure, so it is generally not produced; when stored under pressure, more robust safety facilities are required
Solution: 1. Set up a dedicated line to the torch； 2. Install an ammonia dilution tank; the outlet of the safety valve of the storage tank leads to this dilution tank. Water is filled into the dilution tank to dilute the ammonia gas released when the safety valve activates, and the ammonia-water mixture in the dilution tank is then sent to the acidic water stream for disposal.
Storage at atmospheric pressure is not recommended, as ammonia has extremely high volatility
