Title: Innovations by Sandra J Meischen
Introduction
Sandra J Meischen is a notable inventor based in Florence, AL (US). She has made significant contributions to the field of environmental technology, particularly in the control and measurement of mercury emissions. With a total of 3 patents to her name, her work has implications for both industrial processes and environmental protection.
Latest Patents
One of her latest patents is a method to control mercury emissions from exhaust gases. This invention relates to a method that catalyzes the oxidation of Hg(0) in a flue gas stream prior to standard emissions control equipment. The oxidized mercury is more condensable than Hg(0), making it easier to remove from the gas phase. This method utilizes a porous bed of gold-coated material that catalyzes the oxidation of Hg(0) in the presence of HCl in the exhaust stream.
Another significant patent by Meischen is focused on the determination of total mercury in exhaust gases. This invention includes a system and process to reduce oxidized mercury in exhaust gas to elemental mercury, preventing its reoxidation before photometric measurement. The process involves a reactor heated to about 800°C, where hydrogen is introduced to thermally reduce oxidized mercury species to elemental mercury.
