Latest Patents

One of his latest patents involves installations for processing a product in a gas medium. This installation comprises a blowing chamber where the heat treatment of the product occurs, along with a recovery chamber that surrounds the blowing chamber. Notably, one or both horizontal walls of the recovery chamber are designed to feature a flattened outer duct, which allows treatment gas to be admitted into the recovery chamber, and a flattened inner duct, which facilitates the discharge of a portion of the treatment gas from the recovery chamber. Another significant patent details a process for regenerating an adsorbing material. This process involves the calcination of volatile compounds in a first contacting column, where the material is suspended by an oxidizing gas stream and heated to a high temperature. The gaseous products desorbed in this first column are then re-adsorbed by cooling in a second contacting column, primarily aimed at regenerating alumina particles that have absorbed tars and fluorine-containing compounds.
