Feasibility of tank transfer after liquid ammonia tank leakage
Thread Content
After a liquid ammonia tank leaks, pressure is applied to the leaking tank, using the pressure difference to transfer its contents into the spare (emergency) liquid ammonia tank. Pressurizing the leak tank could increase the leakage rate, preventing the spray from diluting it. Is there such a container that, in the event of a leak from an ammonia tank, allows for pipes to be connected to the leak site in order to transfer the leaking ammonia into this container? Thank you all for helping me understand
It’s not suppression, right? It should be pumped out using an ammonia pump and sent to the backup tank
A double-shell magnetic pump is used, with a flow rate range of 0.1–1000 cubic meters. It features dual isolation sleeves for protection: if one layer fails, the second layer continues to provide protection, triggering an alarm to ensure safety. It can be installed on the ground with a NPSH of 0.5, and it allows the presence of a certain amount of solid particles. Technical exchanges are available if needed
In the case of a liquid ammonia storage area in a factory, it is considered to be a major hazard source. Around the liquid ammonia tanks, there are not only accident dikes but also a range of monitoring and alarm systems as well as sprinkler systems. It is basically impossible to pour the leaking tank into the spare (emergency) liquid ammonia tank by applying pressure! The emergency response plan for liquid ammonia tank leaks must be highly rigorous, and it is essential that it be practical to implement. Therefore, it is generally not feasible to transfer the leaking liquid ammonia into a container after connecting a pipe to the leak site following a liquid ammonia tank leak! !
I successfully reversed the tank for this issue at the beginning of this year. There are two liquid ammonia storage tanks, A and B, at the site. A problem occurred with the primary valve of tank A; therefore, gaseous ammonia from tank B was pumped into tank A using a discharge compressor (two-position four-way valve), which increased the pressure in tank A and forced the liquid ammonia to move into tank B. Two tanks, with the gas phase connected by a compressor and the liquid phase in direct contact. Once the ammonia dumping is complete, there will be a small amount left in tank A; by then replacing it with nitrogen, it can be completely emptied.
