Can an internal floating roof be used for acetic acid storage tanks?
Thread Content
We are currently constructing two acetic acid storage tanks with a capacity of 1,000 cubic meters each, using 316L material. The manager said that internal floating roofs cannot be used due to the lack of a suitable sealing material. So, is it indeed not possible to use internal floating roofs?
What your leader said is correct. It is recommended to equip acetic acid storage tanks with a solid roof and a nitrogen seal, and heating should also be taken into account, as acetic acid crystallizes into a solid state at 16°C.
No. For acetic acid, attention must also be paid to insulation and heat tracing issues, as crystallization occurs easily in winter; the materials for valves and pipelines should also be 316L
