Tank farm ground

Should the floor of the methanol storage area be hardened? Are there any standards for this?
Basically, the ground in the tank area needs to be hardened in order to prevent spilled materials from contaminating the soil.
The construction of the tank farm, like that of other construction sites, requires proper preparation of utilities and a level surface; these are all basic requirements.
Foundations generally consist of soil layers, dry layers, anti-corrosion layers, and so on. For toxic and volatile substances, it is sufficient that the equipment lining of the tanks has good sealing properties. Hardening – this is a process that is generally carried out in all tanks.
Hardening is necessary; the floors of storage areas for light oils, toxic substances, or heavy oils all require hardening. Reason: 1. When a leak occurs in the tank area, it is possible to recover as much of the spilled oil as possible, thereby minimizing losses. 2. It can effectively prevent the land in the tank area from being polluted, and even protect the sources of water supply from contamination. 3. In the event of a leak, the spilled oil can be dealt with centrally, preventing it from flowing away. In particular, in the event of a fire, it ensures concentrated firefighting, preventing the spread of flames that could cause fires in surrounding areas.
In my opinion, it is not necessarily necessary to harden the ground in tank areas!!! Firstly, hardening can generate radiant heat, which increases the loss of stored materials； Second, it increases costs ； Third, some organizations grow grass internally (requiring it to remain green and not exceed 15 mm in length). For reference only! ! :handshake :victory:
Let me share my suggestions. Actually, I’m not entirely sure what the regulations say regarding this issue, but in practical design and production, it doesn’t really matter whether the area is hardened or not. From a production perspective, hardening the area keeps it clean and makes cleaning easier; if it’s not hardened, weeds will grow, which poses a safety risk. But it’s relatively easier if it involves construction and renovation.
For liquid hydrocarbon storage areas, hard flooring is required by regulations; as for oils and liquid chemical products, whether hard flooring is necessary depends on the properties of the products and local environmental protection requirements. “The \"Design Code for Oil Depots\" stipulates that in areas with suitable temperatures, a 0.15m thick evergreen grass lawn can be laid in the tank area, which helps to lower the surface temperature and reduce evaporation losses. In fact, in countries like the United States, there is no hard flooring in the tank areas.
What exactly does “three connections and one leveling” refer to? I haven’t debuted yet; please give clear instructions so I can learn*
Hardening depends on the medium being stored; if there is contamination, hardening is necessary, and methanol must be hardened
It generally needs to be hardened, and good drainage is essential; water accumulation after rain can affect daily operations.
