I have a project involving the recycling of glacial acetic acid, as this substance solidifies below 17°C. So I have been looking for information on the transportation and storage of glacial acetic acid recently. Glacial acetic acid is transported via approximately 130 meters of piping to the storage tank after product preparation. I plan to use 316L material for the pipelines; according to what I’ve found, 304 material does not have as good corrosion resistance at high temperatures. For heat tracing, a steam pipe is placed next to the 316L pipeline, and the two pipes are wrapped together to provide insulation. The material for the storage tank is also planned to be an internal coil-type tank made of 316L material. Due to the large capacity of 15T, an internal coil is selected. (Electrolytic glass storage tanks were considered, but they were ruled out due to their high cost.) A 50-series pneumatic diaphragm pump is planned to be used for transporting the materials. Let’s discuss whether this is feasible or if a more scientific approach could be used.
Intermittent operation of the pneumatic diaphragm pump is also possible
The acetic acid storage tanks in our company are made of 304 stainless steel, so it won’t have a significant impact on quality. We are also internal coil heaters, but our coils are installed at a somewhat high position; heating is not possible for capacities below 150 tons

If it is a tower, the pressure difference created by the tower and its height can be utilized; after the product has been cooled to a certain temperature through condensation, it can directly enter the storage tank without the need for a pump. It is advisable to use 316L material for storage tanks, as acetic acid is quite corrosive; using a lower-grade material may affect certain parameters of the acetic acid product.
