Relining of scrubbers in flue gas desulfurization plants

Rubber lining is used as a corrosion protection material in European flue g as desulfurization plants, for scrubbers, tanks, pipe systems, etc. Althoug h these rubber linings can last more than years, relining still is necessar y. The difficulty of shutting down power station units requires that the ti me scale of this replacement be kept to a minimum. High-pressure water syst ems have proven successful as an efficient method for removal df the old li ning. The working steps and time scale are demonstrated for one such relini ng case.
