Mercaptan oxidation in aqueous waste     Fig. 1. Mercaptan destruction rate.   Tert butyl mercaptan (TBM) and dimethyl sulfide (DMS) are oxidized to destruction in an aqueous-waste solution containing methanol (MeOH), monoethylene glycol (MEG), ammonia and hydrocarbon sources using advanced oxidation process (ozone, hydrogen peroxide and uV). The aqueous solution in the trial mimics the expected waste stream from a gas-transport pipeline. Background to the problem. PSE Kinsale Energy required a process to dispose of an aqueous waste stream in a gas-storage project. Injection gas constitutes odorized natural gas containing 4.7 ppmv and 1.3 ppmv of TBM an
