Abstract:
1. A catalytic wet oxidation system, comprising: a wet oxidation unit; a source of an aqueous mixture comprising at least one undesirable constituent fluidly connected to the wet oxidation unit; a pH sensor configured to detect and monitor a pH level of the aqueous mixture; a source of a catalyst soluble in the aqueous mixture at a detected pH level fluidly connected to the wet oxidation unit, positioned between the source of the aqueous mixture and the wet oxidation unit; and a controller in communication with the pH sensor, configured to 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 the catalyst to maintain the pH level in the predetermined pH solubility range and to maintain the catalyst in a soluble form.
