His innovative approach has led to the development of a patented process that enhances the efficiency of ethylene oxide extraction.
Latest Patents
Michele Sfregola holds a patent for a process aimed at the purification of ethylene oxide. The patent describes a method for purifying crude ethylene oxide present in a dilute aqueous solution. This solution results from the extraction of ethylene oxide from a gaseous stream obtained through the catalytic oxidation of ethylene. The purification process involves desorption, liquefaction, and distillation in a fractionating column, followed by a final desorption treatment to eliminate absorbed non-condensable gases. The fractionating column is heated by the condensation of water vapor evolved during desorption, resulting in a liquid stream of ethylene oxide rich in acetaldehyde. This stream is treated to convert a portion of the acetaldehyde into high-boiling products, which are then distilled and returned to the fractionating column.
