Latest Patents
Natunen's latest patents include a "Method and apparatus for controlling metal separation" and a "Method for removing mercury from gas." The first patent relates to a method and apparatus for controlling continuous metal removal in conjunction with a zinc preparation process. This invention involves measuring the redox potential and acidity or basicity in one or more reactors, allowing for the adjustment of process variables based on measurement results. The redox potential measurements are taken from the sludge produced in the reactor, ensuring accurate control of the metal removal process.
The second patent addresses the removal of mercury from gas containing sulfur dioxide and oxygen, as well as sulfuric acid vapor. This method involves washing the gas with a water solution containing selenium ions, which leads to the formation of metallic selenium. This process effectively precipitates mercury in the gas and vapor, either as a selenide or as a dichloride of mercury and selenium, all while maintaining a low washing temperature below 50°C.
