Abstract
A process is described for monitoring pH in caustic liquor wet oxidation systems. An offgas carbon dioxide baseline value is established for the operating system where oxidized liquid effluent is at pH 7 or above. Offgas carbon dioxide content deviating by a selected proportion above the baseline vale indicates a drop in liquid effluent pH to 7 or less. Sufficient alkalinity is added to the raw wastewater to bring the effluent pH to 7 or above and prevent excessive corrosion to the materials of construction of the nickel-based or ferrous-based alloy wet oxidation system.
