Latest Patents

Deborah's patent, titled “UF₆ - Recovery Process Utilizing Desublimation,” is a pioneering method that allows for the recovery of UF₆ through sophisticated techniques. This invention involves directing a stream of substantially pure gaseous UF₆ through an externally chilled desublimer, converting it into an annular solid ring that adheres to the interior walls of the desublimer. Once an adequate amount of solid UF₆ accumulates, the desublimer is heated to liquefy the solid, allowing for efficient recovery of the liquid. A significant advancement of her process is the incorporation of a small percentage of non-condensable, nonreactive gas, such as nitrogen, which notably reduces mechanical stresses during the heating operation. This modification not only enhances safety but also lowers operational costs and extends the service life of the desublimer and its auxiliaries.
