The patented Zimmermann process involves flameless or wet combustion in aqueous solutions or dispersions. In aqueous dispersions, this process can oxidize a range of organic and industrial wastes to carbon dioxide and water by adding air or oxygen. The wet-air oxidation process (this term preferred by the patentees) does not require de-watering prior to combustion and oxidizes the combustible matter in the liquid phase by applying heat and pressure.
The advantages of this process are that it creates no air pollution and generates sterile, easily filtered, and biodegradable end products. The inherent cleanliness of the fully enclosed system and the potential to generate or recover steam, power, and chemicals are other advantages.
The disadvantages include the need to use stainless steel construction materials and the complex equipment that requires high capital investment and well-trained operators.
