Rubber Liner Removal from Vessel

[pmureiko]

I need advice on removing the rubber liner from a water demineralization vessel that is being scrapped. The liner was to protect the carbon steel wall from acid. The salvage company can't take the vessel with the liner in it.

One firm offered a 40,000 psi water blaster to blow the liner off at $400/hr and 30 hr to complete. I'm confident that will work, but don't want to spend $12,000 for a vessel that will be throw away plus being an outrageous cost.

Try contacting a used equipment vendor and sell them the lined vessel. Make money instead of spending.

Altenatively try heat. If you still have information on the linear find out what temp it was installed at. Heating it above that temp should make it delaminate.

We had a rubber lined treatment tank in our acid waste neutralization system. It came from the factory new with a rubber liner spec'd to handle a cocktail of various acids. No one thought to include the small stream of alcohol and solvent that we passed through in the same waste stream.

The additional solvent and alcohol neatly removed the entire liner from the new tank within two days. Total content of solvent and alcohol couldn't have been more than 4% solution in water.
