Can an ammonia tank be installed underground?
Thread Content
Due to limited space and safety distance considerations, can ammonia storage tanks be buried? The ammonia is 20% concentration and the volume is 50 cubic meters; what type of tank should be used? Is an absorption device necessary for the exhaust gases? What precautions regarding corrosion and leakage prevention need to be taken for buried tanks? Everyone is welcome to discuss
For the 20% ammonia storage tank, what fire classification is used to define it? What is the basis?
Passing by, underground ammonia tanks? I haven’t seen it, so I can’t give an opinion. Please check the relevant standards; it’s quite difficult. Corrosion protection is definitely necessary, and ammonia is hard to handle – it will be tough to arrange proper ventilation
In the specifications for desulfurization and denitrification in power plants, it is recommended that ammonia be classified as Category C
It’s best not to do it underground; safety requirements are becoming increasingly strict, and this could turn into a big problem in the future.
For the 20% ammonia storage tank, what fire classification is used to define it? What is the basis? There are specifications for desulfurization and denitration in power plants, which recommend class C ammonia. Could you tell me which specification makes such a recommendation?
I am working on a project related to cement plants – a project aimed at eliminating excess inventory. The plan is to bury the ammonia storage tanks directly underground, install vent valves, and recycle the exhaust gases. According to Article 4.1.2 of the \"Technical Code for Denitrification Engineering in Cement Plants\" GB51045-2014. The fire separation distances for reductant storage facilities shall comply with the relevant provisions of the current **standard, the Code for Fire Protection Design of Buildings GB 50016. Among them, the fire separation distance for urea storage facilities shall comply with the fire resistance requirements for Class C buildings, while the fire separation distance for ammonia storage tanks and urea solution storage tanks shall follow the regulations applicable to Class C liquid storage tanks. According to Article 4.2.1, Note 6 of the Code for Fire Protection Design of Buildings GB50016-2014 (2018 edition), for horizontal tanks storing Class A, B, or C liquids that are buried directly underground, when the capacity of a single tank is no more than 50 m3 and the total capacity is no more than 200 m3, the fire separation distance from buildings can be reduced by 50% as specified in this table.
