  • Method for removing the rubber lining from a rubber-lined vessel
    Patent number: 4257820
    Abstract: A method for removing the rubber lining from rubber-lined vessels. A pool of solvent is maintained in the bottom of the vessel and heated to produce vapors which will penetrate the rubber lining and attack the adhesive bonding agent which attaches the rubber lining to the vessel wall. This vapor attack is maintained until the adhesive bonding agent is sufficiently weakened to allow sufficient air to be blown between the rubber lining and the wall to separate them.
