Latest Patents

Kiguchi held a patent for a method for the recovery of ethylene oxide. This method involves the recovery of ethylene oxide from gas produced during the catalytic gas-phase oxidation of ethylene with a molecular oxygen-containing gas. The process includes subjecting the bottom liquid of an ethylene oxide stripper to a flashing treatment, which separates the liquid into vapor and liquid phases. The vapor-phase part is then introduced into the bottom of the ethylene oxide stripper in a compressed state, while the liquid-phase part is circulated to the absorber. This innovative approach not only enhances the efficiency of ethylene oxide recovery but also utilizes thermal energy effectively.
