Title: Inventor Spotlight: Stephen Z. Masoomian
Introduction
Stephen Z. Masoomian is a distinguished inventor based in Houston, Texas, known for his innovative contributions to environmental engineering and waste management. With a total of two patents to his name, Masoomian has developed advanced processes and apparatuses aimed at improving the treatment and regeneration of spent caustic solutions.
Latest Patents
Masoomian's latest patents showcase his ingenuity and commitment to environmental sustainability. The first patent, "Spent Caustic Pretreatment and Enhanced Oxidation Process," details a meticulous method for pre-treating spent caustic streams prior to oxidation. This process employs countercurrent multi-stage elevated temperature solvent extraction to remove dissolved organic materials, thereby yielding a pretreated spent caustic stream significantly free of organic contaminants. This stream is then subjected to wet air oxidation and ozonolysis, resulting in a wastewater stream with notably low Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD), effectively neutralized to a pH of 8.5 to 9.0.
His second patent, "Apparatus for Treating and Regenerating Spent Caustic," pertains to an apparatus designed for treating spent caustic solutions at ambient temperatures. This invention combines the oxidation of spent caustic using an air/ozone gas mixture with ultraviolet irradiation, culminating in a filtration process that enhances the quality and resource recovery from spent caustic solutions.
