Under fire conditions in the liquid ammonia vaporizer and reactor, the ammonia release rate through the safety valve is 3000 kg/h. What should be done after the safety valve activates? ? ?

According to GB50160: Ammonia gas must be treated after the safety valve activates. But if absorption is used, the tower becomes too large. Is there any good solution? ? ?
Use specialized ammonia combustion torches and systems.
Add a tank; fill the tank with water. Connect the outlet of the safety valve to the bottom of the tank, using a perforated pipe at the bottom. When the safety valve activates, most of the gas is absorbed by the water, and the remaining exhaust gases are sent to an absorption tower； Pump circulation for towers
Such a large leakage amount is quite significant. Conventionally, as soon as the safety valve activates, the source is necessarily shut off remotely; therefore, even if an absorption tower is used, it does not need to be very large.
