CATALYTIC WET OXIDATION SYSTEMS AND METHODS

A system and method for the treatment of process streams. A catalyst medi ates a wet oxidation process at elevated temperatures and pressures for trea ting at least one undesirable constituent in an aqueous mixture. A catalyst may be selected for its solubility at a detected pH level of the aqueous mix ture. Alternatively, a pH level of the aqueous mixture may be adjusted to so lubilize a selected catalyst and/or maintain the selected catalyst in a solu ble form. A controller in communication with a pH sensor may be configured t o generate a control signal to adjust the pH level of the aqueous mixture in response to the pH sensor registering a pH level outside a predetermined pH solubility range for a selected catalyst.
