METHOD OF OPERATING PURE OXYGEN WET OXIDATION SYSTEMS

摘要

A method is disclosed which comprises operating steps required for safely operating wet oxidation reactors in which combustible substances are oxidized at elevated temperatures and pressures using pure oxygen. The steps satisfy the criteria that a potential of oxidation is established prior to introducing oxygen and maintained until after oxygen flow is stopped; that an inert gas, either from an external source or generated in situ, is present in the reactor from before oxygen flow is introduced until after oxygen flow is stopped; and that the oxygen introducing means is made clean for oxygen use from prior to the introduction of oxygen flow until after the oxygen flow is stopped.
