Can concentrated sulfuric acid storage tanks, as extremely hazardous media, be laid underground? Please tell me, teachers?
Obviously not, there is a leak that cannot be dealt with.

Please refer to AQ 3020-2008 Steel Normal Pressure Storage Tanks Part 1.: Buried horizontal circular single-layer and double-layer storage tanks for storing flammable and non-flammable liquids that pollute water. Structural requirements for underground storage tanks. Since buried storage tanks are installed underground, they are difficult to maintain, and some leaks are not easy to find. In view of these characteristics, structurally avoid multiple outlets on the tank, firstly, to reduce welds and avoid corrosion of concrete on welds, and secondly, to concentrate the pipes on the equipment as much as possible.
What are the reasons for wanting to bury concentrated sulfuric acid storage tanks underground? Concentrated sulfuric acid does not belong to Category A or B flammable liquids, but its fire hazard is classified as Category B because of its oxidizing properties. What other benefits can there be to laying underground besides increasing the cost of some anti-leakage and anti-seepage measures?
Personally, I think it is best not to bury it in the ground. Once a leak occurs, it will be a troublesome matter whether it is detecting or repairing it. As 4L said, what are the benefits of burying it in the ground?
What if a leak affects groundwater?
In addition to the difficulty in detecting leaks in buried installations, welding flaw detection, tank bottom cleaning, and disposal of residual acid after disposal are all troublesome.
If it is to make a concrete pool, put ceramic tiles on it, and put the acid-base tank underground, it is a good idea and it is definitely safer than above ground. If the jar is actually buried underground, both the inside and outside will corrode at the same time. This method is not advisable.
Installation methods such as direct burial underground, above-ground installation, and underground tanks are available in reality. Since direct burial underground is chosen, leakage prevention must be considered first. With the current structural design and anti-corrosion technology (measures), this is not a problem at all. As for cleaning, inspection and maintenance work, there is no big difference between above ground and underground work.
