Can vertical atmospheric storage tanks be sandblasted for rust removal while still containing material? The tank contains media such as methanol and benzene. Thank you to all the experts:handshake :handshake
As a supplement: if it’s possible, what points need to be taken into consideration?
Working with materials present is dangerous, as it generates an open flame and poses a risk of fire and explosion
Surely not, are you outside the tank or inside it? If it’s outside the tank, it’s not advisable to use it even if it’s well-made, as that will generate heat and sparks. If it’s inside a tank, it’s even worse – the operators can’t get in.
Absolutely prohibited! ! ! ! ! ! ! ! ! ! ! ! ! ! !
When handling the storage and transportation of oils, it is essential to be aware of the properties and hazards associated with these liquids. Sandblasting outside a light-duty tank is an extremely dangerous activity – even more so than smoking near the tank. If sandblasting is carried out at night, it creates a scene similar to fireworks, with sparks flying everywhere; the consequences of these sparks coming into contact with oil or gas that has leaked from the tank are imaginable, and such incidents will definitely be reported as accidents. If you are a leader, do not give orders that violate regulations. If you are an employee, do not violate operating procedures.
Cool thermal insulation sealant should be applied to the outer wall of the tank. So, what’s the best way to remove rust? handshake
The main issue is that proper management wasn’t applied during the initial construction phase; the rust removal process wasn’t thorough enough, which led to rust formation and peeling on the outer surface of the tank. As temperatures rise, the cooling insulation material loses its effectiveness, causing the temperature inside the tank to increase and resulting in greater wear and damage. Now we’re asking the construction team to carry out repairs, but there’s still material inside the tank – how can this be dealt with? Urgent! ! !
Direct sandblasting is not possible, as it generates heat that causes the medium inside to evaporate. Manual rust removal using grinding wheels is also not an option; it is better to pour out the medium from the tank before carrying out anti-corrosion measures
In areas with stored materials, open flames and live electrical work are not allowed. Only after pouring out the contents should it be processed!
No. This will introduce new impurities, making the materials more difficult to separate.
Of course not, regardless of safety concerns, it’s at least impossible to operate it. . . It’s better to clean the tank thoroughly first before proceeding
