Latest Patents

Oonishi holds a patent for a "Controlled process for xenon concentration." This invention involves feeding liquid oxygen from the main condenser of the upper rectifying column of an air liquefying/separating unit into a xenon condensing column. The process allows for the evaporation of liquid oxygen in varying amounts, corresponding to fluctuating inputs. The system effectively controls the level and pressure of the liquid in the xenon condensing column, ensuring that quantities of liquid oxygen are vented at a constant level. The vented liquid oxygen is then converted into high-pressure oxygen gas, which is evaporated and supplied to a xenon absorptive column, ultimately recovering it as liquid oxygen through heat exchangers. Oonishi has 1 patent to his name.
