Process of removing carbon dioxide from a chlor/alkali plant tail gas stream

A process for reducing the corrosion of nickel metal in an alkali metal hydroxide evaporator equipment which comprises the step of impressing a total protection potential directly upon the nickel metal material in alkali metal hydroxide evaporator that is in contact with an aqueous alkali metal hydroxide solution during evaporation of that solution; said total potential being sufficient to reduce the amount of corrosion of the nickel metal to an oxide that may dissolve in the alkali metal hydroxide solution.

A process for the removal of mercury from industrial waste streams is disclosed wherein the waste stream is a nitrate based solution that has been decomposed by the addition of hypochlorite. The method involves adding a reducing agent to reduce the hypochlorite and/or adjusting the pH by the use of a strong acid to less than about 2.0, converting any residual chlorine to a soluble unreactive salt, adding a soluble precipitating agent, such as sodium sulfide, to the solution in a ratio to the mercury present of greater than 1:1 to about 2:1 to precipitate out the mercury as a mercury compound. The solution is then filtered to remove the precipitated mercury compound.
