Abstract
A process for separating dissolved corrosive gases from aqueous solutions, e.g., scrubbing waters from a coking operation, is disclosed. The process involves directly contacting the solution with a hot liquid heat exchange medium, such as drops of heating oil, to drive off the dissolved gases. Residual ammonia in the solution is thereafter separated out by blowing steam into the treated solution.
