Regarding the practice of having one storage tank in use and one as a backup for hazardous chemicals (ethylene oxide, liquid ammonia),
Thread Content
Dear experts, I would like to ask which standard stipulates the requirement that for storage tanks of hazardous chemicals such as ethylene oxide and liquid ammonia, one tank should be in use while another is on standby. I’ve searched for this standard for a long time without finding it, but experts say that when using our tanks for storing ethylene oxide and liquid ammonia, one tank must be in use and another must be on standby; the chemicals cannot be stored in both tanks at the same time. I just want to see what the specifications say. Thank you, experts. .
Code for Design of Tank Areas in Petrochemical Storage and Transportation Systems SH/T 3007-2014 4.3.8 The number of storage tanks for raw materials, intermediate materials, and products in chemical processing units should be no less than 2.
I saw this one; there’s a guideline stating that one should be kept as a spare. (If it’s 2, I can use them together, and there won’t be any spare ones left.) . ）
4.3.8 The number of storage tanks for raw materials, intermediate materials, and products in chemical plants should be no less than 2. This is something I’ve also seen; it mainly comes down to whether there is one available and one as a backup ? ? ?
